The West Australian Government has extended its partnership with V8 Supercars to guarantee a round at Barbagallo Raceway for at least the next three years.
The deal, between Tourism WA, the WA Sporting Car Club and V8 Supercars, locks in a Perth event until at least 2018.
The V8 Supercars have competed at Barbagallo Raceway every year (bar 2010) since 1978 - so the extension keeps a long-time staple on the calendar.
The news comes on the same day the 2016 Championship calendar was released, with Perth dates scheduled for May 6 to 8 next year.
WA Premier Colin Barnett announced the news on Inside Supercars this evening.
"Great news for motorsport fans, particularly in Western Australia," Barnett said.
"We are delighted to announce the West Australian Government, through Tourism WA, has reached an agreement with V8 Supercars and also with the WA Sporting Car Club for another three years ... for V8 Supercars at Barbagallo Raceway in Perth.
"It is a terrific agreement and great news for motorsport fans in Western Australia."
V8 Supercars Chief Executive Officer James Warburton - who featured on the Inside Supercars panel - was pleased to keep the national category in WA.
"Absolutely fantastic," Warburton said.
"I'd like to start by thanking Premier Barnett - we've had a fantastic association with Barbagallo Raceway and Tourism WA.
"But it's not just the event itself, it's the facilities there and what it does for motorsport. As much as we only go there one weekend a year, the reality is that circuit and the continued investment in the infrastructure there is something that all West Australian motorsport codes can enjoy.
"It's a wonderful event and we're delighted, Premier, and look forward to getting back to WA on the first weekend of May."
Barnett said WA was proud of the facility it has developed, and sees the V8 Supercars Championship visit as one of the key parts of its events calendar.
"Fifteen million dollars has been spent on Barbagallo Raceway and it's not only great for the drivers, but the spectators - facilities are terrific now and we're very proud of that," Barnett said.
"Motorsport is very popular here ... we get a great crowd along and [have a] huge following.
"For West Australia and tourism, great national television coverage. Also the international coverage is a huge boost for Western Australia as we build up our events calendar."
Next year's calendar sees not only a return to the usual favourite tracks, but a new event to be staged in Malaysia with the KL City Grand Prix to host a Championship round in August.
