The Wallabies' Rugby World Cup plans have taken a hit following the surprise resignation of attack coach Scott Wisemantel.
Wisemantel said family reasons and business interests outside of rugby were behind his decision, which comes eight months out from the Rugby World Cup in France.
He joined the Wallabies as a senior member of head coach Dave Rennie's staff in late 2019.
Wisemantel was an assistant coach under Eddie Jones when England reached the 2019 Rugby World Cup final in Japan.
He had previously worked with Japan and Samoa, in addition to an earlier stint with the Wallabies.
"While this has been a very difficult decision, it's one that's best for me and my family at this point in time," Wisemantel said in a statement.
"The World Cup is the pinnacle of our sport and requires 100 per cent commitment and that's something I'm unfortunately unable to give at the moment.
"I've loved being with this team under Dave and wish them all the best for their season and in the World Cup later this year."
Rennie said he and Rugby Australia tried to persuade Wisemantel to stay.
"Scott's a top man and one of the best coaches I've ever worked with," Rennie said.
"He's hugely respected around the world, has a mountain of experience at International level and an incredible rapport with our players.
"While we did all we could to try and keep Scott, we respect his decision.
"He's been a massive part of this group for the past three years and we'll miss him."
Wisemantel's decision comes five months after Matt Taylor stepped down as Wallabies defence coach.
The Wallabies — who only managed five wins from 14 matches in 2022 — confirmed they had begun the process to find a replacement for Wisemantel.
