On my web site today I noticed a Google AdWords advertisement from the Australian Government "Water for Our Future". Curiously the ad was on a posting about government web standards, unrelated to water use.
This links to a Department of Sustainability, Environment, Water, Population and Communities web page about the controversial Murray-Darling Basin Authority report "Guide to the Basin Plan", which recommends cuts to irrigation water allocations. There is an online form for providing feedback and a Australian Water Education Toolkit intended for schools. Although presenting only one side of the argument, the material is well presented, about the only lack is some form of online forums where the issues could be discussed.
ps: Two of the towns which will be effected by the water plan are Leeton and Griffith, which were designed by Walter Burley Griffin and Marion Mahony Griffin.
