PERTH, Australia, Jan 30 (AFP) - Australian captain Shane Warne expects world champion one-day side Sri Lanka to bounce back Sunday in a crucial clash here after their humilating defeat by England at Perth's WACA Ground Friday.

``This is a make-or-break game for them -- and I'm sure they will bounce back,'' Warne said Saturday as the Australians went through their paces for a tri-nations tournament match they also want to win to boost their finals prospects.

``I am sure Sri Lanka's opening pair, Sanath Jayasuriya and Romesh Kaluwitharana, will come out swinging from the start like they always do.

``They are dangerous at the start ... they could get them off to a start of 90 or 100 off the first 15 overs, and if that happens, they will make a half decent score,'' said Warne

``So it is very important for us to get somne early wickets.

``We have a few tactics up our sleeve which we will use tomorrow.''

Sri Lanka must conquer Australia to have any chance of playing off in the lucrative showdown next month for a first prize of 100,000 Australian dollars (63,000 US) after being crushed by England by 128 runs under lights Friday.

Sri Lanka sent in England, who made 227-7, and were then humbled for 99, with the last nine wickets toppling for 34 runs.

England, with five wins, top the ladder with one more success than Australia. Sri Lanka are languishing with only two victories.

Sri Lanka and Australia each have three more qualifying games, while England have two.

Warne believed the WACA Ground bounce was again the demon which derailed Sri Lanka's batting aganst England.

``They have not played too many games here for a while, and England are playing some very good cricket,'' he said.

``Australia are also playing well at the moment, so it is tough for Sri Lanka.

``We are hoping for a good win so we can go to equal top in the table.''

Australia's trump card appears to be champion fast bowler Glenn McGrath, whose lifting deliveries gave him a five-wicket haul against Sri Lanka in Adelaide last Sunday.

He has been the outstanding bowler in the series, with 17 wickets at an average of 16.82.

``If we could choose where we play Sri Lanka, it would be here in Perth,'' Warne said.

``In Adelaide, we saw McGrath and our other guys bowl a bit of short stuff, so we hope it will be much the same here.''

Australia will be strengthened by the return of ace batsmen Ricky Ponting and Michael Bevan.

Warne was not prepared to become involved in the politics of the past week, sparked by Sri Lankan captain Arjuna Ranatunga's action in leading his players to the boundary and holding up play for 12 minutes in the game against England.

Ranatunga was demonstrating against Australian umpire Ross Emerson's decision to no-ball controversial off-spinner Muttiah Muralitharan for throwing.

International Cricket Council match referee Peter Van der Merve imposed a suspended sentence of six one-day internationals on Ranatunga, as well as fining him 75 per cent of his match payment, a sum of about 200 Australian dollars (126 US).

Howls of protest greeted the decision, with many in Australia and overseas describing the penalty as absurdly inadequate.

``We were not involved in the game. I think everybody was disappointed with the outcome,'' was all Warne would say.

Teams (in probable batting order):

Australia: Mark Waugh, Adam Gilchrist, Ricky Ponting, Darren Lehmann, Damien Martyn, Michael Bevan, Shane Lee, Brendon Julian, Shane Warne (capt), Mike Kasprowicz, Glenn McGrath, Adam Dale (probable 12th man).

Sri Lanka: Sanath Jayasuriya, Romesh Kaluwitharana, Marvan Atapattu, Aravinda de Silva, Arjuna Ranatunga (capt), Mahela Jayawardene, Roshan Mahanama, Upal Chandana, Chaminda Vaas, Muttiah Muralitharan, Ruchera Perera, Suresh Perera (probable 12th man).
