However, Quinn's investment into Triple Eight marks his biggest step yet in the Australian motorsport landscape.
He will not have a full-time role in running Triple Eight, and his investment is separate to sponsorship.
There are also no plans in place for Quinn's other companies to have involvement with the team.
"We're delighted to welcome Tony to the Triple Eight family," Triple Eight Commercial Operations Officer Jessica Dane said in a statement.
"Over the past two decades, he's established himself as one of Australia's leading businessmen, remodelling and growing household names including V.I.P. Petfoods and Darrell Lea with astounding success.
"We are flattered that someone of his pedigree approached us and sees Triple Eight as the most worthwhile investment in Supercars.
"He's also a known figure in the racing industry, where his passion has seen him tick boxes around with world as a competitor, sponsor, category owner and circuit owner.
