The trio will drive an Audi R8 LMS GT3 in the Pro-Am division, carrying #44.
Andrews is an experienced head in sports car and GT racing, having won the LMP3 class in the 24 Hours of Daytona in 2021.
The Miami-based Australian has split his efforts across LMP2, LMP3, and GT3 racing, competing almost exclusively in the IMSA SportsCar Championship.
This year Andrews will return to the Daytona 24 with Lone Star Racing in the GTD division.
There, he’ll join Lone Star Racing in a Mercedes-AMG GT3 with Dan Knox, Eric Filgueiras, and Ralf Aron.
Pires and Zalloua raced in GT World Challenge Australia this year, Pires claiming second in the Am standings.
“Super excited to have another crack at the 12 Hour we have had some bad luck in the last few years so hoping the mountain chooses us this time,” said Pirez.
“We are stepping up to ProAm but feel that we are more ready than ever to give it a red hot shot.”
Zallou added: “It’s exciting to be going back to Bathurst in the new-look Geyer Valmont Racing Audi R8.
“We are excited to have Scott join the Geyer Valmont Racing team for this year’s race.
“I am sure he is coming to win, so we are ready for the challenge and as always keen to take it to the bigger and more high-profile teams and drivers.”
