Telstra Rally Australia is the second international event to back the Subaru Rally Challenge.
The six-event series starts with the Subaru Rally of Canberra in May, a round of the Asia-Pacific Championship.
Canberra organisers have declared that the one-make series will have its own designated service area and that entry fees have been reduced to $1000 for the Impreza RS series competitors.
Subaru Rally Challenge patron, reigning Australian Rally Champion Cody Crocker, says the opportunity to compete at international events is a huge plus for the series participants.
"Subaru Rally of Canberra will be a great experience for the competitors to start and now there is the lure to compete in a world championship round for the top three at the end of the year," Crocker said.
"It is fantastic that Telstra Rally Australia has seen the value in the Subaru Rally Challenge and got behind it in such a meaningful way.
"The opportunity to compete in a WRC round with the best drivers from around the world present is the dream of most rally drivers."
John Berne, from New South Wales, has joined Ben Tirant, Eli Evans, Mark Beard, Steve Glenney, Trent Brand, Matt Van Tuinen, Darren Windus and Gavin Mosher as confirmed starters.
A further six cars are under construction ready for sale to competitors.
It is anticipated that at least 15 cars will start the series at the Subaru Rally of Canberra on May 8.
Orders for further cars are still being considered by Subaru Australia. Prospective competitors should call Monica Zeaiter at Subaru on (02) 9828 9227.
