There is water, and plenty of it, flowing into the great inland Lake Eyre, but a flood of a different kind is happening on its banks.
Tourists are flowing thick and fast into William Creek to take a look at the phenomenon that is a Lake Eyre filling, with the water levels already higher than they were for the last filling in 2010.
William Creek publican and Wrightsair director - and owner of pretty much everything else in the Oodnadatta Track outpost - Trevor Wright says the Far North of South Australia is as busy as he has ever seen it.
At the end of April, the surface of Lake Eyre was already more than half covered with water and the tourists were flowing into the small outpost.
By the start of this month, the Lake was three quarters full, significantly more than when it reached one third full in 2010, and a second flush is expected to hit the lake across the second half of June.
In William Creek, the town filled to capacity weeks ago and Mr Wright says an overflow campsite has been set up.
"It is really pumping at the moment... we are flt out with flights and across the town,'' Mr Wright said.
"It is a really positive thing for William Creek and the whole region and great to have so many people discovering this magnificent part of the world.''
