Frenchman Sebastien Ogier can seal a third straight World Rally Championship crown with victory in Australia.
The Volkswagen driver has dominated this year, winning six times and finishing second twice in nine events.
Ogier (207 points) is well clear in the drivers' championship, leading Jari-Matti Latvala (114) and Andreas Mikkelsen (98).
With a max of 112 points up for grabs for the remainder of the season, Ogier is well-placed to secure the title in New South Wales.
Thursday will mark the start of the race in Coffs Harbour as Ogier aims to add to the titles he won in 2013 and 2014.
"I love Australia and am always pleased to be here," Ogier said.
"The city is great and the people here are very chilled out."
With wins in Portugal and Finland, Ogier's team-mate Latvala is the only other driver with multiple victories in 2015 and Brit Kris Meeke was victorious in Argentina.
Ogier's dominance means Volkswagen are almost certain to win the manufacturers' title, sitting on 300 points and well ahead of Hyundai (161).
