Sri Lanka's cricket governing body decided to send controversial off-spinner Muttiah Muralitharan to Australia for expert assessment after he was reported for a suspect bowling action.

"He will be filmed by the University of Western Australia before professor Bruce Elliot and Daryl Foster," Sri Lanka Cricket said in a statement.

"Professor Elliot is also a member of the ICC Human Movement Panel," the statement said.

Muralitharan was reported by match referee Chris Broad after the third and final Test against Australia in Colombo on Sunday.

In contention is Muralitharan's new delivery, the "doosra" which spins away from the right-handers.

Muralitharan finished the three-Test series against Australia with 28 wickets to take his tally to 513, needing seven more to break retired West Indies paceman Courtney Walsh's world record of 519.

Prof Elliot studied Muralitharan during the initial complaints about his bowling in 1995 and 1998 and concluded his bent-arm action created the "optical illusion" of chucking.

He said earlier this week he wasn't surprise by the latest reporting because of the attention given to Murali's doosra ball.

"People had expressed worry to me and I had said 'yes it would seem logical that he had his action tested'.

"When he got tested before he didn't have that ball. It's not something that we've looked at."
