A plan to use recycled water, which currently runs out to sea, could double the production of food in Australia's salad bowl, avoiding future vegetable imports by shoring up domestic supply.
The Lockyer Valley Somerset Water Collaborative, west of Brisbane, said the region was among the most fertile in the world, but much of the land remained under-used because there was not enough water to produce food crops.
The collaborative was made up of representatives from local government, farming and business communities, and under its plan, recycled water currently running out to Moreton Bay would come from Wivenhoe Dam via a pipe scheme, costing $200 million to build.
