Money and Australian Universities
“There are many dangerous beasts in this world. Betrayed partners, taipans and Collingwood supporters all score highly. But above all, never come between a sandstone university and a trough of money.” The Australian Financial Review, pg 54, February 26, 2009.
Better Planning for Extreme Floods Possible: A Note from Stewart Franks
DESPITE increased understanding of a number of different climate processes and their impact on a range of different timescales, this knowledge is not being used to inform planning and decision making. This is because long-term climate risk is often viewed only in statistical terms.
For instance, engineering techniques for estimating flood risk, where records exist, are largely based on simple statistics of their historic occurrence rather than on any real understanding of the processes that actually cause them.
In essence, if we have 100 years of flood record, then the largest flood measured represents, more or less, the hundred year flood level. This hundred year flood level is probably the most important of hydrological statistics in terms of its use in planning management. It is the yardstick by which decisions are made.
The problem with a simple statistical representation of risk is that it implies a static climate – the expected flood risk is equally likely in any year, irrespective of the actual climate processes that may or may not be dominating at that particular time. If this were the case, we would expect to see an equal spread of floods throughout our historical records. In Australia and in fact many other parts of the world, this is not so.

The Humble Axe and Chainsaw: A Note from Ian Mott
CHEAP, simple to use and extremely effective fire management tools that are owned and operated by almost every householder who is exposed to the risk of wildfire are the humble axe and the chainsaw. But the various native vegetation “protection” laws around Australia have effectively outlawed their use, even in the most extreme emergencies.
Indeed I have lost count of the number of published images of the Victorian fires that provide clear and damning evidence of our legislator’s role in the manslaughter of so many innocent Australians. Almost every image of a burned out home also exhibits the unmistakable signature of ill-informed social engineers who have abused their legislative powers to compel, what is now clearly proven to be, one of the most destructive social changes ever forced upon a minority community.
The facts clearly establish the case that the Victorian and other state governments around the country have made a direct contribution to the character, scale and intensity of the wildfires, and the death and destruction they have caused. They made critical choices as to the form and content of seemingly unrelated legislation which has banned the use of some of our most readily available and effective fire risk management tools.
And they have not just implemented that legislation in a manner that has prevented efforts to improve fire management and lower the associated risks. These people have established a policy architecture that has actively discouraged, on pain of penalty, rural people from preventing the state sponsored deterioration of fire management conditions and all the increase in risks associated with it.
In the days when large fires were fought and defeated by men and women without machinery, pumps, water bombers or GPS, the axe was an essential tool for reducing the height of the fire face at key defensive positions. My own father, the late T.R. Mott, spent most of the 50 years of volunteer firefighting, that earned him an Australia Medal, carrying the day with axe and hoe.
