As exclusively revealed by Motorsport.com, Hill emerged over the Gold Coast 500 weekend as the runaway favourite to land the second MSR seat.
The GM has now made its 2023 line-up official, with Jack Le Brocq and Hill set to drive its two Camaros.
Hill will be one of two rookies in the Supercars field next year alongside current Super2 rival Matt Payne.
The Canberran has an impressive CV which includes winning both the Australian Formula Ford (2015) and Carrera Cup (2021) titles driving for his family-run CHE Racing squad.
This year he finally stepped out of the family team for what was his first season in a Supercar, joining Triple Eight for Super2.
He currently sits fourth in the second-tier standings with a round to go, while he also made his Bathurst 1000 debut last month with PremiAir Racing.
His rookie main game Supercars season will coincide with the introduction of the new Gen3 rules.
“It has been a goal of mine for years to compete at the highest level here in Australia," said Hill.
“We have massive potential here at MSR. The team has been building towards Gen3 for some time now.
"Everyone will have brand new cars, and I see it as a big opportunity for myself and the team to make an impact. It's the first time the playing field will have been level for years.
“I am grateful that [owner] Matt [Stone] and the team see my potential and are giving me this opportunity”
For Stone, who has made his intention to sign a rookie clear since Todd Hazelwood's impending departure went public, Hill is the ideal teammate for the experienced Le Brocq.
“It’s exciting to have another rookie in the fold here at MSR," he said.
"And in Cam, we see a lot of great potential with the experiences and success that he has had in multiple categories over the past few years.
“I think he is the perfect fit for the changing dynamic that comes with Gen3.”
Confirmation of the Hill deal is expected to lock in the field for the 2023 Supercars season, barring any unexpected changes at four-car teams Brad Jones Racing or Tickford Racing.
