The news follows confirmation earlier today that Le Brocq will depart Matt Stone Racing at the end of the current campaign.
The 31-year-old, who scored his second victory in Supercars at Hidden Valley in June, is now locked in at Erebus alongside championship leader Brodie Kostecki for 2024.
He becomes the latest domino to fall in the driver market amid Shane van Gisbergen's impending switch to NASCAR.
Le Brocq has long ties to Erebus, having ran in F3 and Australian GT as an Erebus Academy driver early in his career. He also made his main game Supercars debut as an Erebus enduro co-driver in 2015.
“We have witnessed Jack’s journey and some of his achievements firsthand, and we’re thrilled to welcome him back to the family,” Erebus CEO Barry Ryan said.
“Obviously, we still have five rounds remaining this season, and right now our focus in on winning the drivers’ and teams’ championship.”
Remarking on his return to the Erebus fold, Le Brocq said: “Erebus is a team that has been instrumental in my career, and I am excited to re-join them next season.
“I look forward to contributing to Erebus’ ongoing success in 2024, though my immediate focus is on giving my all for the remainder of the 2023 season with my current team.”
