In January 2009, heavy rainfall associated with an active monsoon trough and low pressure system, and the ensuing Tropical Cyclone Charlotte, fell along regions in northern Queensland. Subsequent flood warnings were issued for rivers situated along the coast from Cairns to Mackay. Major rivers affected included the Mulgrave, Russell, Haughton and the Don. Cairns airport received 189 mm of rain over a three hour period, with many coastal areas receiving in excess of 300 mm over 24 hours.

The heavy deluge caused damage to infrastructure, houses and buildings.

The Insurance Council of Australia estimated the 2009 damage at $19m. This is the combined total for Tropical Cyclone Charlotte and Tropical Cyclone Ellie. (see separate entry for North Queensland floods 31 January 2009)
