Justin Langer will have a new right-hand man at the World Cup and Ashes following the sudden exit of Australia's bowling coach David Saker.
Saker has resigned, effective immediately.
Troy Cooley will serve as bowing coach on upcoming limited-overs tours of India and the UAE, but Cricket Australia is yet to make a call on Saker's full-time replacement.
Saker had been the national bowling coach since 2016.
He boasted plenty of knowledge about UK conditions, having previously worked as England's bowling coach before returning home to mentor Victoria.

But Langer was keen to bring in a fresh perspective for this year's marathon tour of England, during which Australia will defend both the World Cup and Ashes, and Saker accepted it was time to go.
"We shook hands and had a hug a day after the Test (in Canberra)," Langer said.
"We agreed it's the right time to head in a different direction in the best interests of the team.
"He and I have had a lot of conversations over the last six or nine months, so it's not really a surprise.
"In a perfect world it would have been cleaner maybe at the end of it, but the world's not always clean and works exactly as you want it to work. I'm all good with it."
Saker had previously spoken of his desire to be a potential successor to Darren Lehmann in 2017, when he filled in as head coach during a ODI tour of India.
It's unclear how much Saker's relationship with his charges deteriorated this summer, if at all, but Mitchell Starc notably had credited NSW's bowling coach Andre Adams for helping to end his form slump.
Australia's fast bowlers had plenty of knockers during their Test series against India, while Saker was publicly critical of their approach at the SCG.
Saker revealed during that match that "aggressive" and "animated" discussions took place behind closed doors.
"That's not like me usually ... I know I was not the only one. JL (Langer) wasn't happy. The bowlers know that," Saker said.
"The bowlers wanted one thing. Tim wanted one thing ... you could see there was some confusion."
