The Eggleston Motorsport driver had his first taste aboard the V8-powered Hilux last week, completing a day of testing at the Eastern Creek circuit.
“I am so excited to race a SuperUte this weekend,” McLean told Supercars.com.
“I’ve been looking for ways to expand my racing skillset and this opportunity came up, so I jumped at it.
“I had some running in the Hilux last week and we were fast, so I’m really looking forward to what I can put together this weekend.
Haltech V8 SuperUtes Series Manager Luke Sieders added: "Unfortunately Ben Walsh is unable to travel to NSW with the current border restrictions in place, but luckily Matt reached out to us at the right time.

"We are really excited to be able to give Matt some quality track time to help him with his preparations for the upcoming Super2 round in Sydney.
"It's great for SuperUtes to help develop young talent on their way to the Supercars Championship, through offering relevant racecraft in a cost-effective way."
