Sadly, even if the heavy rains were to cease immediately, there is already a mighty reckoning travelling south towards the NSW border and beyond along the Condamine River. The 10 metres pulse that has devestated Chinchilla and Dalby is a far rarer event than the rains which have falled east of the Great Divide and the tropical rains of the far north.

Rain around Bundaberg east of the Great Divide will move straight out to sea - ensuring the worst water visibility around the Whitsunday Islands for the last 10 years. Imagine snorkelling through a mild green chicken curry - you get the picture.

The northern rains will eventually find their way into Lake Eyre which not so long ago was a 20 year event. 2011 however marks the third year in a row that Lake Eyre will be full.

The Condamine River and other similar Murray Darling tributaries do not handle flooding well, its to rare an event, thats why the flooding they are currently experiencing is record breaking. The further the rains move along towards the Murray and ultimately the Coorong down at South Australia before entering the southern ocean the more diluted the effects will be. This year though theres more water than even the greediest NSW cotton farmer could ever dream of.

The Queensland town of Saint George looks set to suffer major flooding in a few weeks depending on how well the dam at Beardmore can contain the water - no one really knows, it's never really been tested. Beyond that there are around another dozen towns and settlements set to receive the deluge in around a months time

...but what happens if the rain doesent stop?
