The 2009 Repco Rally Australia was the 20th Rally Australia and the tenth round of the 2009 World Rally Championship season. The rally consisted of 35 special stages and was won on the road by Citroën's Sébastien Loeb. However, Loeb's win was short-lived as his Citroën along with those of his teammate Dani Sordo, and Sébastien Ogier were given one-minute time penalties for irregularities with their cars' anti-rollbars. Ford's Mikko Hirvonen inherited the win, for his fourth win in succession.

Rally Australia is an automobile rally event which was held in Coffs Harbour as the final leg of the World Rally Championship (WRC) until 2018.
