Walsh received his first taste of full-time V8 Supercars action with Erebus in 2015 having been a proven performer in the category's breeding ground, the V8 Supercars Dunlop Series, as well as a V8 Supercar co-driver in recent years.
After his rookie year was cut short, he returned to the wheel of a Supercar to co-drive with Tim Slade at Brad Jones Racing last year, impressing in all three PIRTEK Enduro Cup events.
He returns to the Freightliner Racing Holden in 2017 looking to avenge disappointment at Bathurst, where brake problems hampered a strong run.
Walsh earned the right to test himself against the best after finishing as runner-up in the Dunlop Series Drivers Championship in 2013 before backing that up with a third place finish overall in 2014.
Ipswich-born Walsh commenced his career in Formula Ford, where he set a national record for winning nine consecutive races on route to finishing runner-up in 2007.
A stint in Europe followed where Walsh raced competitively in British Formula Ford for Australian Team, Borland, and in the Western European Championship Formula Renault 2.0 for HiTech Junior alongside the likes of current Formula One star Daniel Ricciardo.
His performances saw him recruited as a rookie test driver for A1 Team Australia where he matched it with other rookie drivers before the series concluded.
Walsh returned to Australia and after a brief period away from racing, returned to Australian Formula Ford before a successful foray into the Dunlop Series, firstly with Miles Racing before joining Matt Stone Racing.
