The Oasis Change report published on hotspotting.com.au has attracted a remarkable level of interest around Australia. It's been featured in news bulletins on Channel 7 and Channel 9, about 25 radio stations and a similar number of newspapers.

For those who think we're exaggerating when we predict that home buyers and investors will make choices based on water supply, here's a few snippets about Brisbane's situation.

Brisbane's main water source is Wivenhoe Dam. It's down to 16.4% of capacity. Other sources are Somerset Dam, down to 27.5%, and North Pine Dam, close to empty at 13.6% of capacity. There's a very real prospect that South East Queensland, the nation's greatest growth area, could run out of water.

The State Government is trying to fast-track completion of a pipeline to bring recycled water to South East Queensland. But spiralling expenses, partly caused by efforts to speed up construction, have caused a $600 million cost blowout. It will now cost $2.4 billion.

The project will connect waste-water plants in Brisbane and Ipswich to a recycling plant at Bundamba, near Ipswich. Once purified, the water will be used to supply major power stations and industry, and eventually will be pumped into Wivenhoe Dam to top up household water supplies.

Do you see how desperate the situation is? The Queensland Government is spending $2.4 billion so that Brisbane residents can drink their own (treated) effluent.

Beyond the state capital, there are other communities is dire need of water solutions. Almost two-thirds of Queensland is drought-declared, encompassing 85 municipal areas.

This is why some families are packing up and vacating places like Brisbane in search of cities and towns with secure water supplies.
