The separation of water ownership from land was brought on by the Howard government in 2004, but it has created a double-edged sword as anyone can buy water as a commodity and then hold that water in dams, year after year, while regional communities go without. Why have we allowed 20 per cent of groundwater and 15 per cent of water licences to come under foreign ownership in Australia? And I'm relating my question mainly around the Murray-Darling Basin.
