Matthew Wade concedes Peter Nevill is currently the better wicketkeeper, but he is confident brutal batting can keep him in Australia's one-day side.

Wade is in a unique position among the squad currently in the West Indies for an ODI tri-series, which continues when Australia face South Africa in St Kitts at 3am AEST on Sunday.

The Victorian is the only player assured of playing all six games in the tournament, or seven if Australia reach the final.

With Nevill Australia's current preferred 'keeper in Tests and T20s, Wade's performances in the Caribbean could play a major role in deciding which gloveman takes part in the next limited-overs tour in Sri Lanka later this year.

"I feel like in the one-day game I've got the ability to win games with the bat," Wade said in St Kitts on Friday.

"I think you need a little bit more balance - keeping and batting - in one-day cricket.

"I'm the man for the job.

"I've been in the one-day team consistently since the end of the (2015) World Cup, so I feel like I've had a good amount of games to back it up and feel comfortable."

It is an intriguing selection showdown that has played out since Brad Haddin's retirement last year.

Not since the overlap between Adam Gilchrist and Ian Healy's careers has Australia had separate ODI and Test keepers.

Wade was dumped in favour of Nevill for the World Twenty20 in April, a decision that prompted speculation Wade was out of favour with selectors.

"They went with the best keeper in the country," Wade said.

"That is Peter Nevill at the moment. We all know that, that is why he's the Test keeper.

"I was pretty comfortable with that selection."

Meanwhile, Proteas skipper AB de Villiers is eyeing a second consecutive win over the world's No.1 ODI side, believing it will give his side a chance to gain a mental edge over Australia ahead of this summer's three-Test series.

"Any victory against an opposition leaves a little bit of a scar," de Villiers said.
