Lehmann: Only four players assured of spots

Updated: 

Australia coach Darren Lehmann promised changes for the third Test against South Africa, with most of his players to be sent back to domestic cricket.

All of Australia's 11 in Hobart bar Josh Hazlewood, Mitchell Starc and Joe Mennie will feature in the Sheffield Shield.

It comes in the wake of the hosts' embarrassing loss by an innings and 80 runs to South Africa in the second Test on Tuesday.

The majority of the team will return to domestic cricket starting Thursday, with Lehmann calling on players to put their hands up.

"We've got to make sure we're going in the right direction for Australian cricket because at the moment we haven't been," Lehmann told a news conference.

"We've got to win some games, we've got to stop the rot, if you like, to start with and then obviously start to play some good cricket again.

"It's a really good chance for all the players that are playing Shield cricket this weekend to put their hand up."

After being bowled out for 85 in the first innings, Australia lost 32-8 in the second in the huge loss.

Seemingly only pacemen Hazlewood and Starc, opener David Warner and captain Steve Smith are assured of spots.

"Guys that have played in this Test match, obviously some are disappointed in their performances and they get a chance to play the Shield game to put their hand up," Lehmann said.

"Obviously we've got some world-class bowlers, I thought Hazlewood was great, Starc's obviously getting back to his best and then you've got Smith and Warner.

"Outside of that, everyone has got to make some runs and take some wickets so it's a really important four days of Shield cricket.

"The lads know, they're keen to get out of here, get ready to play for that game and prepare the best they can.

"Spots? I don't know. As a selection panel at the end of the day, performance is going to count but then you have to have an eye to the future as well so it's that juggling act."
