Floods and storms occurred across south-east Queensland and northern New South Wales, causing damage to cars and homes. The Gold Coast recorded rain totals of 368 mm in a 24 hour period. The New South Wales Premier declared Lismore, Byron Bay, Tweed Heads and Ballina natural disaster zones. 

Flood warnings were issued for major rivers from mid-north New South Wales to southern Queensland. In the northern New South Wales town of Lismore the Wilson River peaked and as a precaution, approximately 3000 residents were asked to evacuate their homes.

Thousands of people in northern New South Wales remained stranded by the flood waters days after the storms and were reliant on food and medical drops by boat and helicopter.

The Insurance Council of Australia estimated the 2005 damage at $25 million, with the 2011 estimated normalised cost of $37 million.
