Water Basics What is a Megalitre? One Megalitre (ML) is 1 million litres, or 1,000 cubic metres. One Megalitre covers approximately 1 square kilometre to a depth of 1 millimetre. One Megalitre is about equal to the volume of 1 Olympic sized swimming pool. 1

What is a Gigalitre? One Gigalitre (GL) is 1,000 million litres. One Gigalitre is approximately equal to the volume of 1,000 Olympic sized swimming pools.

Significant events since the April 2007 editions include: 1.

Skyrocketing prices of oil and energy resources.

2.

Cost increases to build power stations.

3.

Ever decreasing inflows to the Murray-Darling Basin [MDB]2 , which threaten imminent collapse to our rural communities.

4.

Rising salinity levels and falling Murray River3 inflows are killing the Coorong and Lake Alexandrina.

5.

Commonwealth plans to implement a Carbon Trading Scheme by 2010.

Another Climate Change Threat Assessment

Executive Summary This is an Action Plan to counter the critical drought crisis facing Southern Regions of our ‘Clever Country’ – Australia. This plan hinges upon: 1.

Sourcing new water for the Murray River – According to Prof. Mike Young, inflows of 2,000 Gigalitres per annum are required, just to sustain the Murray River segment of the Murray Darling Basin.

2.

A potential source for this vast amount of water has already been reported by Mr. Kenneth Davidson4 , a Senior Journalist with ‘The Age’. His proposal hinges upon piping water via submarine pipeline from Tasmania to Victoria/Melbourne.

In an effort to reduce stress on the Murray River caused by outflows along the Goldfields Superpipe [linking Bendigo and Ballarat], additional measures include: 1. Construction of a Multi-Effect Distillation (MED) Desalination Plant at Portland, Victoria. 2. Utilise 2 methods of reducing heat energy operating costs by: a. Incorporating the massive heat byproduct generated by the Portland Aluminium Smelter via Heat Exchanger Technology5 . b. Sourcing the proven geothermal resource 1,400 metres below Portland. 3. Concurrently develop water infrastructure [pipelines and pumping stations] for supplying potable water from the Portland Area Groundwater Reserves, with a total drawdown capacity of approx 60,000 Ml p/a, northward to: a. Hamilton, Mortlake and Ballarat with links to other major towns and communities along this route. Distance is approx 290 kms. b. Origin Energy has announced that it is committed to proceed with the construction of a 550 MW Gas-Fired Power Station near Mortlake6 .

c. Santos has announced plans for the construction of a 550 MW Gas Fired Power Station, at Orford7 , near Port Fairy, which will also require water for operational purposes. d. Beaconsfield Gold [ASX: BCD] has recently announced the discovery of a significant high grade copper, gold, nickel and silver deposit near the Grampians8 in Victoria [Hamilton – Mortlake highway] – the extent of the resource is still being analysed, however, if mining begins, there will be a significant increase in the demand for water for the mine, and associated population increase.

4. Ensure that a proportion of this water flows into the Murray River enabling both environmental flows and extraction downriver for the Adelaide water supply. 5. Establish consistent recharge of water into depleted Groundwater systems from the Desalination Plant.

6. Utilise this additional water for the ongoing development and maintenance of long-term drought & bushfire mitigation programmes for topsoils, groundcover and shelterbelts in the Western & Central Districts of Victoria.

We therefore need to: 1.

Secure guaranteed water resources to feed & water our population, increase groundcover and protect valuable topsoils from erosion.

2.

Switch our energy generation capacity from bulk unprocessed coal-based fossil fuels in a step-by-step method to: a. Introduction of briquette value-added coal processing that can reduce Carbon & NOX emissions by up to 50% - clean coal technology. b. Replace older Coal-fired Power Stations with Coal Seam Gas [CSG] and Liquefied Natural Gas [LNG] power generating systems that incorporate the Cogeneration Process9 , [Combined Heat & Power]10 , thereby increasing power station efficiency from 35% up to 90%. c. Accelerate the development of geothermal, wind and solar renewable energy generating systems for inclusion into the National Grid.

Another Climate Change Threat Assessment

Introduction There has been much debate about whether Climate Change is a fact or a myth. The exponential growth of scientific evidence is now clearly indicating that we are heading into a paradigm shift in global weather patterns. Much of the major scientific focus has recently been on Climate Change Effects on our Cryosphere.11 A project currently being conducted by Associate Professor Ross Edwards of the Desert Research Institute12 in the US, is to research Antarctic Ice-Cap Meltdown which is being driven by: 1. Pollution from Industry, Coal Fired Power Stations, bushfires & firestorms, including fires created for land clearing. These aerosol pollutants are then carried within air currents over the Ice-Caps where they are deposited onto Greenland, the Arctic and Antarctica. 2. Photo-chemical pollutant molecules, including Black Carbon [BC], then blanket the snow and ice-cover. 3. This film of pollution reduces the Reflectivity Index [Albedo Effect]13 of the snow, thereby increasing the heat absorption rates. Only subtle amounts of pollution are required to increase the snow-melt rates, as per the graphic below, [courtesy of Hugo Ahlenius, UNEP/GRID-Arendal].

As the Principal Investigator, Ross Edwards has been awarded funding from the US National Science Foundation14 to undertake the project. The rationale for the investigation includes: “The intellectual merit of this project is that black carbon (BC) aerosols  result solely from combustion and play a critical but poorly quantified role  in global climate forcing and the carbon cycle.   When incorporated into snow and ice, BC increases absorption of solar  radiation making seasonal snow packs, mountain glaciers, polar ice sheets,  and sea ice much more vulnerable to climate warming.”     “BC emissions in the Southern Hemisphere are dominated by biomass  burning in the tropical regions of Southern Africa, South America and  South Asia. Biomass burning, which results from both climate and human  activities, alters the atmospheric composition of greenhouse gases, aerosols  and perturbs key biogeochemical cycles.     “The broader impacts of the project are that it represents a paradigm shift  in our ability to reconstruct the history of fire from ice core records and to  understand its impact on atmospheric chemistry and climate over  millennial time scales.     This type of data is especially needed to drive global circulation model  simulations of black carbon aerosols, which have been found to be an  important component of global warming and which may be perturbing the  hydrologic cycle.”

Substantial destruction of Australian forests and biomass by bushfires in 2003 within the ACT resulted in the Canberra Firestorm15 – in this event 4 people died and over 500 homes were destroyed within the National Capital. The Gippsland Bushfires16 of 2006, which destroyed over 1 million hectares of bushland, farms and forests. This event created massive Green House Gas [GHG] emissions and the smoke plume was last seen on satellite imagery heading south-east, probably increasing the levels of BC pollution in Antarctica. For Australians, this reality is reflected in the continuation of low rainfall events in the southern parts of the continent over the past 10 years. The main thrust of the debate in how to address our chronic drought crisis has revolved around how much funding should be put into irrigation buy-back schemes. Commonwealth and State Governments are already committing hundreds of millions of dollars in Drought Relief Programmes. Whilst these measures will assist the rural community during this drought, they will never provide a solution to future low rainfall events – lack of water. The city of Ballarat, 1 hour north-west of Melbourne, is an example of how bad things can become. This graph of the Central Highlands Water17 storages within the Ballarat District provides a stark example of the ongoing crisis.

We have not yet reached the hot summer months, what then? Whilst Ballarat is not located within the Murray-Darling Basin, it is drawing water from the Goldfields Superpipe, which connects the Murray-Goulburn system to Bendigo and Ballarat. Meanwhile, the MDB crisis is worsening because of the continuing drought conditions. The Coorong area at the mouth of the River Murray is close to collapse and irrevocable damage 18 .

An article in TheWashington Post, 19 by Doug Struck in late 2007, reports that the UN has warned that we have only 7 years to end emissions growth. “To  avoid  heating  the  globe  by  the  minimum  possible,  an  average  of  2  degrees Celsius, the worldʹs spiralling growth in greenhouse gas emissions  must  end  no  later  than  2015,  and  the  report  said,  and  must  start  to  drop  quickly after that peak.   By  2050,  carbon  dioxide  and  other  atmospheric  polluting  gases  must  be  reduced by 50 to 85 percent, according to the estimates.”  

In another article in ‘Science’ magazine, by Thomas Stocker, 20 from the Physics Institute of the University of Bern, Switzerland: “Levels of atmospheric carbon dioxide are the highest they have been in  650,000 years, according to the first in‐depth analysis of tiny air bubbles  trapped in an ice core from East Antarctica.   In two articles analysing air from the ice core published in the journal  ʺScienceʺ today, European researchers have extended the greenhouse gas  record back to 650,000 years before the present, adding 210,000 years to  previous records.   One study chronicles the stable relationship between climate and the  carbon cycle during the Pleistocene Era, 390,000 to 650,000 years before the  18

This would require a drastic reworking of industrial processes, transportation, agricultural practices and even the buildings people live in, according to this report.

Current Situation The Big Picture The average rainfall trends for the past 50 years for Australia are clearly displayed in the Bureau of Meteorology Map (BOM) below.

It is evident that many high population areas along the Eastern and Western Seaboard are receiving significantly less rainfall over the past 50 years – population and water demand is upwards – but the rainfall trend is downwards. Less rainfall will see a reduction in the harvests from Australia’s Food Bowl – declining grain harvests and decreases of livestock within sheep/cattle growing areas. This will have a serious effect on our Primary Production at a time when: • There are food riots across the globe21 as a result of dramatic rises in staple foods, droughts, hurricanes, typhoons, floods and a reduction in food production. 21

• Transport costs have risen sharply because of recent spikes in fuel and energy costs.

The Rainfall Deficiencies map from the BOM22 for the past 15 months to August 2008 clearly illustrates that the continuing low rainfall pattern continues.

This is a pattern that continues from the 2002 – 2003 drought, which had very serious consequences for the nation. The Department of the Treasury compiled a full Report on the Economic effects of this drought, as per their web reference.23

Region of Interest The Region of Interest (ROI) of this paper encompasses the Southwest, Western and the Lower Murray Basin in Victoria. The area extends from the Southern Victorian coastline around Portland, northwards to the Murray River in the Mildura/Swan Hill region. Much of this area, including the Mallee and Wimmera districts are under a continuing cycle of serious drought. The Victorian Dept of Primary Industries – Storage Level Report at the 8th of September, 2008, reflects a truly gloomy picture across Victoria, as per the map below.

Groundwater Reserves The groundwater reserves are also becoming an increasing concern. There are no rising levels in our groundwater24 reserves. This adds weight to the proposal that both surface, and aquifer resources, require a realistic replenishment plan.

The Case for Desalination “I love a sunburnt country, A land of sweeping plains,  Of ragged mountain ranges, Of droughts and flooding rains.” 27   

 

 

 

 

 

Dorothea Mackellar 

We no longer experience the same weather patterns that Dorethea Mackellar did when she penned her observations about the ‘flooding rains’ that recharge the rivers, streams and aquifers. Compelling reasons for the construction of a Thermal Desalination Plant in Western Victoria include: • High risk of rural sector collapse without new sources of water. Significant reductions of primary production exports. • An increase in farm walkouts, in an article28 entitled ‘Farmers Abandoning Drought-Hit Properties’, by Kelly Ryan, in The Australian, on 13th October, 2006. • In a CSIRO publication29 entitled ‘Climate Change Impacts on Fire Weather in South-east Australia’, by K. Hennessy, C. Lucas, N. Nicholls, J. Bathols, R. Suppiah, & J. Ricketts in 2006, there is evidence of increasing risk of Bushfires & Firestorms because of future hotter and drier weather conditions. • Litigation – In an article entitled ‘Farmers Sue State over Bushfires’, reported in The Age, by AAP on 22nd March, 2007 – class action in relation to The Christmas 2006 bushfires in the Gippsland area – launched by Slidders Lawyers30 in Melbourne on behalf of more than 500 residents who have suffered damage as a result of these bushfires and firestorms. • Erosion – Drought reduces groundcover, precious topsoils are at extreme risk of eroding during dust storms. This begins a cycle of soil degradation and loss 27

that becomes even more serious if long-term drought is followed by flooding rains. • Topsoils – This Department of Primary Industries (Victoria) paper, entitled ‘Paddock Protection & Stock Management During Dry Times’, by John Williamson 31 of Bendigo spells out the facts about topsoil loss. “In dry periods, soils become more susceptible to wind erosion as a result  of  the  removal  of  the  protective  vegetative  soil  cover.  This  is  caused  by  stock  grazing  and  the  trampling  of  the  soil  surface  degrading  the  soil  structure.   As a consequence, strong winds are able to erode soil particles, depositing  them  either  as  drifts  along  fence  lines  or  at  locations  up  to  thousands  of  kilometres away. Eroded soils and animal  manure can foul both domestic  and stock water supplies decreasing the potability of the water.”   “Sandy soils are renowned for blowing during dry periods, however all soil  types are susceptible.  Erosion  of  topsoils  by  wind  takes  with  it  nutrients  such  as  nitrogen,  phosphorous and organic carbon all of which are vital for the health of the  soil and production.”   “With every 1 mm of topsoil eroded, approximately 13 t/ha of topsoil, 130  kg/ha of organic carbon, 20 kg/ha of nitrogen equivalent to 40 kg of urea  and 8 kg/ha of phosphorous equivalent to 100 kg of superphosphate are  lost.   Phosphorous  and  some  nitrogen  can  be  replaced  through  fertilizer  however  organic  carbon  and  nitrogen  take  years  of  appropriate  management to build‐up in soils. 

Desalination Plants There are several types of desalination plants. The major ones include: 1.

Multistage Flash Desalination (MSF) – a thermal process – seawater is first heated under high pressure before being fed into the 1st ‘flash’ chamber, where rapid pressure release causes the seawater to quickly boil. This ‘flashing’ process evaporates some of the seawater, and the process continues through more ‘flash chambers’, each with a step-down in 31

ambient pressure. The water vapour generated in this process is condensed and collected from tubing cooled by the seawater feed. Only a small percentage of the incoming seawater-feed is evaporated and collected. This method produces about 84% of the world’s potable water from Thermal Methods. Most of these plants have been built in the Middle East where energy reserves are plentiful. The main problem with these plants is high construction, materials & operating costs. The ‘flash’ chambers require the best quality stainless steel in tubes and chambers32 , to prevent scale buildup, thereby reducing effectiveness. 2.

Multi-Effect Distillation (MED) – also a thermal process – similar to the MSF process, however the seawater-feed is not heated under high pressure. In the MED chambers, reduced ambient pressure is used to boil water at lower temperatures. Saltwater boils at slightly above 100O C at Standard Temperature and Pressure (STP). With the reduced pressure effect within the MED Chambers, it boils at about 65O C 33 . This significantly reduces the energy and therefore the operating costs to run the facility. Higher numbers of chambers (Effects) equates to higher performance ratios.34

3.

Reverse Osmosis (RO) – a non-thermal filtration process using membrane technology – saltwater is pumped at high pressures of 800 to 1,000 psi through a semi-permeable membrane. There are numerous stages involved in the pre-treatment process, depending on the contamination levels of the saltwater-feed – i.e. suspended solids and divalent ions like Calcium and Magnesium. This process is prevalent in the US, where energy costs are too high for thermal processes.35

Of these processes, MED would appear to provide the best value with its low temperature operational costs, particularly when Cogeneration and Geothermal resources are combined within the Energy Cycle. There is also the requirement that sterile water be used for aquifer recharge due to a seabourne virus within Victoria that causes ganglioneuritis, a herpes-like disease that is killing the wild abalone.36 This may appear to seriously compromise any desalination effort by a filtration process using Reverse Osmosis (RO) methods. Strict quarantine protocols will be required for any process where water is directly injected into aquifers during the recharge process. 32

Energy Costs The on-going operational energy costs for an MED desalination plant should be drastically reduced by using the 2 significant heat resources within the Portland area: 1.

Heat byproduct of the smelting process at (PA) Portland Aluminium. Management at PA have expressed an interest in this concept.

2.

Portland Geothermal Bores. A number of bores had been in service from the early 1980s. The Portland #14 bore flowed under artesian pressure of up to 90L/sec at approx 60O C.37 Other bores produced 74 O C. Whilst this bore has been recently decommissioned, this site has proven potential for redevelopment.

3.

The full report by SKM (Sinclair Knight Merz) provides 10 pages of detail about the Portland Geothermal Bore field.

Full costings for such a plant are dependent upon plant type, size, and energy sources, however, the 2 papers listed below provide comprehensive details: • A paper by Neil M Wade38 of the UK, entitled ‘Distillation Plant Development and Cost Update’, compares the various available desalination processes. • Conference paper by J.E. Blank, G.F. Tusel & S. Nisan, entitled, ‘The Real Cost of Desalted Water and how to Reduce it Further’39 , presented at the Conference on Desalination Strategies in South

Mediterranean Countries – Cooperation between Mediterranean Countries of Europe and the Southern Rim of the Mediterranean on 21–25 May 2006, at Montpellier, France.

The authors have researched those major Desalting processes [including RO, MED] that will be operating in 25 years. There are direct links between each process, the cost of energy, oil and type of Power Generation used, to provide Industry with informed options that suit their particular needs.

Why Portland Portland Aluminium Smelter This facility generates in excess of 340,000 tonnes of Aluminium per annum. The smelter is managed by Alcoa and uses approx. 10% of the total State electricity supply in Victoria, and is one of the highest export earners for Victoria. Some vital statistics about average datasets for Australian Aluminium production40 include: Energy costs are about 30% of operating costs Electricity levels of approx 15 KWh required per Kg of metal produced. Requires approx 3 Megalitres of water per tonne of metal produced. Green House Gas (GHG) emissions of approx 2.5 tonnes CO2-e per tonne of metal produced. Greenhouse gas emissions are becoming an increasing area of concern with activist groups adopting a more militant stance toward industry. Many industry leaders are seeking ways of both effectively reducing their greenhouse gas emissions and ‘value-adding’ other goods and services by utilizing by-product development. This will then achieve acceptable results to both communities and the corporate ‘bottom-line’.

Bushfire Risk There is little point in providing groundcover and shelterbelts if we are unable to protect our crops, livestock, forests and communities. Events such as the Ash Wednesday, Canberra, Grampians and Gippsland bushfires clearly highlight the increasing risk of devastating fires in the Southern parts of Australia. “The  impact  of  periodic  extreme  fire  weather  is  amplified  by  the  “corner  effect”  as  cold  fronts  round  the  eastern  boundary  of  Victoria  and  violent  southerly  changes  stream  northwards,  sometimes  governed  by  stationary  high pressure cells in the Tasman.”   “The  combined effect  is  to  place Victoria  into  one of  the  acknowledged  most fire dangerous parts of the globe.”   “From  a  community  perspective,  this  physical  and  meteorological  arrangement  has  historically  manifested  itself  in  severe  fire  seasons  through substantial loss of life, sometimes involving many fatalities, heavy  loss of assets and extensive areas subjected to intense fire.” 41

The Victorian Country Fire Authority employs strategies and tactics that may utilise: • Modern Fire Appliances, including 4 Wheel Drive units. • Bulldozers. • Spotter aircraft. • Sophisticated satellite imaging technologies. • Fixed and rotary wing aerial water-bombers – crop-dusters and Elvis. • Small unit Strike Teams As detailed in the Commonwealth Parliamentary Select Committee Report42 , there have been serious problems in our ability to combat bushfires – perhaps it is time to increase equipment and resources to safely meet the increased fire threat – introduce Armoured Strike Teams.

Background – Armoured Warfare The first successful use of armour by Australian Commanders occurred in World War I in the campaigns on the Western Front. Development of Armoured Warfare Strategies and tactics was a result of the stalemate and significant loss of life created by the defensive trench systems that were used across the entire Western Front. An Australian Commander who saw the need for a new style of warfare that could be successful against defensive lines of trenches was General Sir John Monash. His key to success may be summarized as follows: “…..the true role of infantry was not to expend itself upon heroic physical  effort, not to wither away under merciless machine‐gun fire, not to impale  itself on hostile bayonets,  …..but on the contrary,…..  …to  advance  under  the  maximum  possible  protection  of  the  maximum  possible array of mechanical resources, in the form of guns, machine‐guns,  tanks,  mortars  and  aeroplanes;  to  advance  with  as  little  impediment  as  possible; to be relieved as far as possible of the obligation to fight their way  forward.”  43

Whilst many believe that the tactics that Monash developed and prosecuted would only apply in war-fighting, it is perhaps time to apply some of his wisdom toward more successful methods in fighting bushfires and wildfires. In fire-fighting tactics, we are already using a large number of ‘mechanical devices’, such as ‘fire trucks/tankers’ and ‘aeroplanes’ like firebombers and helicopters, [Elvis], to fight bushfires – but, is it now time to introduce tanks?

Problems in Fighting Bushfires Apart from the report, ‘A Nation Charred – Report on the Inquiry into Bushfires’, there have been coronial inquests [Canberra Firestorm], and reports by CFA members, farmers and graziers on the difficulties encountered in battling bushfires.

Some of problems identified include: • Poor fire trail management44 “The  Committee  witnessed  the  poor  state  of  fire  trails  in  the  Kosciuszko  National Park where it inspected a section of the Grey Mare fire trail on 21  May 2003 in the company of Rural Fire Service (RFS) Group Captains, the  Fire Control Officer and his Deputy from the region.”   “During  this  inspection  the  Committee  experienced  the  great  difficulty  of  travelling  over  deep  channels,  or  ‘tank  traps’  as  they  are  known  locally,  that  were  deliberately  built  into  the  trails  after  the  fires  to  discourage  access.” 

• Safety concerns in accessing the Fireground.45 “A representative of the Central East Regional Conference of the Rural Fire  Service  Association  (RFSA)  and  Captain  of  the  Round  Corner  Bushfire  Brigade in Baulkham Hills, Mr Ross Jones, stated that:  “I have personally  refused to go down trails because I believed them to be unsafe … especially  with regard to the fire behaviour that could be expected to impact on us.”

• Safety concerns in times requiring hasty withdrawal.46 “The  Director  of  the  Victorian  Association  of  Forest  Industries  [VAFI]  explained  the  significance  of  maintaining  fire  trails  to  adequate  specifications;   The difference between one bulldozer width and three…[is]  that you….  1. 

Cannot turn a fire truck around as easily, 

2.  Are  still  going  to  have  the  overstory  touching  and  the  fire  can  move across there and..  3. 

Cannot start a backburning operation safely.” 

• Deliberate sabotaging of firetrails.47 “Another  experienced  volunteer  fire  fighter  from  the  area  stated:    “National Parks hired a friend of mine, who is a bulldozer driver, to make a  fire  trail  on  the  eastern  side  of  Mountain  Lagoon  impossible  to  use  …   When the fire was in operation, because the Mountain Lagoon Fire Brigade  had the authority they hired my mate with the bulldozer to clean [the trail]  up.    Before he had even moved away again, National Parks hired the same man  to go back and rip it all up again.” 

• Fire fighting vehicles – Modified off-the-shelf fire-fighting tankers. o There are several problems in using standardized, commercial, truck cabs and chassis units as a basis for frontline Bushfire Vehicles. These shortcomings have been detailed in a paper by Bruce Paix 48 , entitled “Improving Burnover Protection for Australian Bushfire Appliances,” in 1999. In this paper, weaknesses were identified in the following vehicle elements: o Vehicle Cabins: Windows and Door Trims – commercial truck cabs have flammable vinyl/synthetic interiors. 46

These can ignite and/or smoulder, giving off toxic vapours and smoke, forcing the fire-fighters to abandon their vehicle, which may well be their only refuge. o Fuel Tanks – Commercial trucks often have unprotected fuel tanks, which may increase vulnerability. o Airbrake lines – One notable feature of truck braking systems is that any drop in air pressure in the lines due to damage will cause the brakes to “lock-up”. An occurrence on the fireground, or burnover, effectively immobizes the truck and the crew is at extreme risk. o Flammability of other Vehicle Parts – includes tyres, fuel lines and hoses. In some cases these have caught on fire and led to the complete destruction of the truck. o Mechanical Failures – engines have failed to start or run when they are subjected to intense heat and smoky conditions. Burning embers have got into the engine and burned out the turbocharger, again immobilizing the vehicle o Sudden Bushfire Changes – Bushfire characteristics such as intensity, direction, sudden wind gusts or wind shifts have suddenly changed, resulting in entrapment of fire-fighters and their vehicles.

Australian Built Fire King Perhaps the most exciting element within the proposed new Armoured Strike Team is the Fire King, as it has already been proven as World Class. This vehicle is probably the best 4WD/AWD fire-fighting vehicle in the world, and is currently in service with the South Australian (SA) Forestry Department as their most effective fire-fighting asset. The authors have tested this vehicle in the Mount Gambier Forestry area. The Fire King easily traversed steep gradients over very soft sands encountered along firebreaks and easily traversed overland areas that would have bogged/stopped any normal 4WD vehicle.

The Fire King, in self protection mode, during terrain evaluation tests at Mt Gambier, SA. Crew access is via a central door at the rear of the cabin, eliminating the risk of fire burning through door seals as can happen with traditional vehicle configurations. Emergency exits are through side cab windows, clearly seen in this photo.

Major features of the Fire King include: 1.

Already proven to be a world class fire-fighting vehicle.

This vehicle is the result of additional development from the outstanding military variant – the Bushmaster, used by the ADF.55 56

4.

Extensive testing by the CSIRO under controlled, monitored and consistent heat loads for 20+ minutes – proven vehicle survivability by driving off the burnover test pad.

5.

Run-flat tyre inflation system. Should the tyres be staked/punctured, the on-board compressor maintains adequate tyre inflation enabling vehicle to withdraw safely.

6.

Maximum protection of crew from fire – state-of-the-art armour plate & glass/windscreen that can withstand 1,000 deg C. temperatures. During CSIRO burnover testing, the cabin temperature rose by no more than 15 deg C above ambient air temperature.

7.

Approx weight empty – 10.2 tonnes: Weight full – 14.2 tonnes.

8.

Max speed – 100 km/h. (restricted by Forestry SA). Constant road speed easily maintained due to superior power of the engine plant, an intercooled turbo-charged Caterpillar diesel of 300 hp.

9.

Water carrying capacity of 3,000 litres (firefighting) + 700 litres (reserved for vehicle protection).

10.

Low centre of gravity – the design of the vehicle allows the water tank to be fitted deep within the monocoque chassis, lowering the centre of gravity in comparison to current pumper/tanker configurations – lessening the chance of rollover.

11.

The independent suspension design allows the Fire King to travel across the roughest terrain whilst retaining excellent stability and crew comfort offroad. The 6 speed automatic transmission, with power steering, enables any CFA member to safely handle this vehicle in any terrain.

12.

Options for fit-out include purchase of the cab-chassis from Thales. If the rear of the Fire King layout, as currently utilized by Forestry SA for plantation firefighting, is not suitable for CFA requirements, then the current unit used on current CFA vehicles could be fitted to the Fire King, subject to engineering specifications.

Conclusion The need for action Climate Change will create a labyrinth of issues in the coming years. The whole problem of GHG emissions will not be solved by focussing on any single element. It requires a focus on all the elements, how they interrelate with each other, and how we have had substantial influence upon the situation in which we now find ourselves. These basic elements include: • Earth • Fire • Wind • Water • Air Many commentators state that Australia is really a ‘very small fish in a very big pond’, and therefore cannot have a leadership role in driving positive outcomes in combating Climate Change. The Murray-Darling Basin is not just a story about purchasing back water licences, any more than it is about asking farmers and communities to accept that their river systems are beyond salvage. It will require effort on a national scale, not seen since the Snowy Mountains Hydro-electric Scheme. There are currently 32 Australian companies involved in developing geothermal resources, and many others working in clean coal, solar & wind renewable energy projects. Additionally, there are the social issues of responsible environmental and water management that will be thoroughly scrutinized by the public and the press. The drought story continues to unfold. Many of our forests, farms, rivers, communities and cities will soon die of thirst or become devastated by bushfires in the coming summer seasons – unless we act. Water is the key element and we need to make a start now.
