Tourism WA is backing the fixture, and Supercars’ visit to Barbagallo on May 4-6.
In the very south-eastern corner of Australia, Holdsworth and rookie Stanaway headed to Hobart, to promote the Tyrepower Tasmania SuperSprint on April 6-8 at Symmons Plains near Launceston.
Among their activities, the pair took to the picturesque Huon River in a jet boat.
“It was good fun on the jet boat,” Preston Hire Racing’s Holdsworth said.
“We went down the Huon River, it was a beautiful river, and then went through the rapids and swerved in and out of the logs.
“It was good fun, an eye-opener and it’s good to get out and see a bit of Tasmania.”
Tickford Racing’s Stanaway raced at Symmons Plains in the Australian Formula Ford Championship, before taking his career to Europe.
“The first time I raced here in Tassie was back in 2009, so it’s been a while for me, but it’s at least one of the circuits on the calendar where I have raced at before,” he said.
“Obviously I’ve got to learn it slightly differently with a Supercar, but it’s a circuit that creates great racing.
“The field’s always really close and there’s a couple of really good passing opportunities; I’m really looking forward to racing there.”
Before the SuperSprints, teams will race for points and the Larry Perkins Trophy for the first time at Albert Park on March 22-25 in the Coates Hire Supercars Melbourne 400 as part of the Australian Grand Prix weekend.
