Justin Langer is yet to decide if he wants to replace Darren Lehmann as coach of the Australian men's team, saying it's a "complicated" decision given the sacrifices involved.

The 47-year-old is among the frontrunners to take over from Lehmann, who resigned last month in the wake of the ball-tampering saga in Cape Town.

Langer has long been considered the natural successor to Lehmann and the events in South Africa have brought forward the search for a replacement.

The coach of Western Australia and the Perth Scorchers, Langer said accepting the job would mean walking away from a happy family life with his wife and four daughters in Perth.

"If the opportunity came up, there would be a lot to consider," he told PerthNow.

"The complication is that I love my job. I love my job here. I love being on the board of the West Coast Eagles (football team). I love being with my family all the time.

"I am a Perth boy and I love being home. So that’s why it is complicated.

"I’m also involved with five or six charities here in WA. And walking away from all that is not that easy to do.

"I have a great life as we speak."

Ponting on coaching and the hurdles facing Australia's T20 team

Langer stood in as head coach for Australia's ODI tour of the West Indies in 2016 when Lehmann took some time off, a strong indication the former Test opener was the next in line for the top job.

The taxing nature of the role has also led to speculation that the position could be split between formats, with a separate coach for Test, ODI and T20 teams.

Langer's former captain Ricky Ponting has already expressed his interest in coaching the national T20 side, while former Australia fast bowler Jason Gillespie has previously discussed a desire to coach at the highest level. Gillespie, like Langer, has also maintained that he enjoys his current coaching roles, with the Adelaide Strikers and Sussex.

Langer, Ponting and Gillespie teamed up to take charge of Australia's T20 side in 2016 when Lehmann was on duty with the Test team.

Speaking after Lehmann's shock resignation in South Africa, CEO James Sutherland said Cricket Australia would take its time in selecting Lehmann’s replacement given Australia’s next international assignment is a five-match ODI series in England in June.

"I wish the team the best for the last Test with Darren in charge," he said.

"I know there is a lot of talented coaches in the coaching ranks back in Australia, but I also reflect on the fact that amongst international cricket there are a number of coaches that are performing very well."
