Warne has launched a bid to coach Australia in the three-match T20 series against Sri Lanke early next year in a caretaker role while Darren Lehmann is in India preparing for a Test series.

Warne is considered one of the best cricket minds in the business and has the support of Australia’s cricketing elite.

Lillee said Warne would do a fine job as mentor of the national side.

"You talk to anyone and they say Warnie has one of the best cricketing brains around", Dennis Lillee told 7News.

"So as a coach surely that's the main thing. I think he would make a great coach.”

Warne had been critical of the role coaches played in the national side a view Lillee seemed to share with the spin king.

"I counted the number of people out on the ground the other day", Lillee said.

"There was 11 players and 17 support staff. Does that sound a bit out of whack?"

Cricket Australia confirmed Warne had approached them about the short-term role.

"We are speaking to a number of people about the prospect of coaching the T20 international squad against Sri Lanka as head coach and assistant coach, Darren Lehmann and David Saker, will be in India," a CA spokesperson said.

"At this stage no decision has been made on an appointment."
