Jason Gillespie says he doesn't want to coach Australia's cricket team, while describing Justin Langer's messy exit from the job as "heartbreaking".

Gillespie, who is South Australia's coach and a former coach of English county sides Sussex and Yorkshire, had been touted as potential replacement for Langer.

"I am not putting myself up for any job," Gillespie said.

"It's nice to be thought of in that way but it's certainly something I am not even thinking about entertaining."

Gillespie has reached out to former Test teammate Langer, who quit on Saturday as Australia's coach.

"Everyone has been pretty disappointed with how it has all played out — pretty heartbreaking to see, to be honest," Gillespie said.

"But unfortunately, it is what it is.

"Justin has handled himself very well … the decision has been made and whatever decision they make, they make.

"But I think everyone is of the opinion that things probably could have been handled better.

"He is OK.

"He felt he had something to offer Australian cricket. Cricket Australia felt differently.

"So move on, that's part and parcel I suppose of being in professional sport and being a coach."

Gillespie praised Langer's four-year tenure as national coach.

"Justin will go on and do wonderful things that we all know he can," he said.

"He has done a fine job with Australian cricket the last four years and we all wish him really well because he will succeed in whatever he puts his mind to."
