Australia's World Cup campaign has reportedly suffered a crippling blow just hours before the team's departure for France.
According to Australian sports website The Roar, assistant coach Brad Davis has announced he's quitting the team for personal reasons.
Davis' resignation is effective immediately, with the squad scheduled to fly out of Sydney to Paris on Thursday afternoon.
Tasked with overseeing the Wallabies gameplan, Davis had reportedly clashed with head coach Eddie Jones, who returned to take charge of the team, after Kiwi predecessor Dave Rennie was fired.
The team have yet to record a win under Jones' guidance, losing all of four of their Rugby Championship and Bledisloe Cup tests in 2023.
Davis joined the Wallabies from the financially embattled London Wasps, where he was an assistant under new Queensland coach Les Kiss. He's expected to reunite with Kiss in the same role with Queensland Reds next season.
Australia play France in a World Cup warm-up on August 28 (NZ time), before their tournament opener against Georgia on September 10.
