Now a boffin from the Commonwealth Department of Climate Change and a proff from the ANU are warning us all that sea levels may rise even further than expected before the century ends.
With "700,000 homes located within 3km of the coast and less than six metres above sea level" Australia is running out of time.
"Speaking on the first day of the Coast to Coast 2008 Conference in Darwin, Dr Mummery said there were "major information gaps'' in Australia.
Preliminary modelling has found that if there is a rise in sea levels, 269,505 houses could be at risk in NSW and 2,875 houses in the NT.
Dr Mummery - from the federal government's Department of Climate Change - said a rise of only one metre could put a number of Gold Coast properties at risk and impact on canal development."
You don't have to be Einstein to see how things might shape up for the NSW North Coast on these projections.
So where're the maps, Morrie?
We know you have them - fork 'em over so we can all plan an orderly retreat from the sea if need be.
