Australia have opted to bowl and named an unchanged XI for their high-stakes Twenty20 World Cup clash with West Indies in Abu Dhabi.
Aaron Finch's team will have one foot in the semi-finals if they win their final pool game of the tournament.
Australia and South Africa are locked in a tight battle to finish second in their group, having both banked three wins from their opening four matches.
The Proteas face England in Saturday's late game, with the semi-final berth to come down to net run-rate (NRR) if Australia and South Africa both win or both lose.
Australia hold a 0.289 NRR advantage over South Africa, having bounced back from a lopsided loss to England by racing to victory over Bangladesh with a record-breaking 82 balls to spare.
"Not one bit," Finch said after winning the toss when asked if run-rate would be on his side's mind.
"We don't think about that whatsoever.
"We come here to try to win."
West Indies have recalled spinner Hayden Walsh Jr in place of Ravi Rampaul.
Dwayne Bravo has confirmed this will be his final international match, while 42-year-old opener Chris Gayle is also expected to retire after this World Cup.
Australia XI: David Warner, Aaron Finch (capt), Mitch Marsh, Glenn Maxwell, Steve Smith, Marcus Stoinis, Matthew Wade, Pat Cummins, Mitchell Starc, Adam Zampa, Josh Hazlewood
