Authorities say rainfall and flooding will be the most significant threat, with 300-600mm of rain expected in some areas and localised totals reaching 700mm. Flood watches are in effect from Bundaberg to Port Macquarie, and Brisbane City Council has warned that 20,000 homes could be impacted by flooding.

Brisbane Lions coach Chris Fagan has called for the game to be postponed, as Queensland Premier David Crisafulli says he has spoken to the AFL.
