Aaron Finch's side has found a rich vein of form ahead of hosting the seventh edition of the tournament in October.

A quirk of the international schedule means India will host the following World Cup just 12 months later rather than the standard two-year gap.

Warner, who will turn 34 later this year, has conceded that continuing to play all three international formats will eventually be too demanding and with Test cricket his top priority, T20s are likely to be the first on the chopping block.

But rather than bowing out on home soil, Warner is keen to take advantage of the shorter gap and potentially finish up at the 2021 World Cup.

"I definitely would be motivated to go to the next World Cup," he told reporters in Johannesburg.

"When you've got such a great bunch of guys together and you're enjoying that journey, you don't really want to leave that.

"At the moment we're in a great place as a team and I'm just really excited to be a part of it again.

"This is my fifth or sixth World Cup, but I definitely feel like this is the team that has got the best chance of winning, especially at home."

Australia will continue their road to the World Cup on Friday night (Saturday morning AEDT) when they face South Africa in the first of three T20s at the Wanderers.

The schedule this year is dominated by white-ball matches, including T20s in New Zealand next month and England in July.

"The scheduling the last 12 months has been perfect in that sense, that we've had opportunities to play the series," Warner said.

"I think it's a testament and credit to the selectors to stick with the one kind of team. And giving guys that clarity of their roles ... it's having that clear plan when you go out there.

"You look at the past, we've picked six openers. That's not going to work. And the game plans just don't work. And I remember batting No.4 in India - it's not my position but I was able to put my hand up and say 'well, we've got to fit someone else in'.

"Now we know the roles, it's all clear, there's definitely going to be no excuses."
