Australia's women aren't shying away from their chance to make history as they approach the Rugby Sevens World Cup in South Africa.

They go in to the Cape Town-hosted tournament looking to complete their 'triple crown' and add a World Cup to the Commonwealth Games gold medal and World Series title they've already claimed this year.

And the men are also coming in hot, fresh from claiming their maiden World Series title just last week in Los Angeles as Australia enters the Cup with both number-one ranked sides.

Women's captain Charlotte Caslick says her side have no excuses if they couldn't seal the major milestone.

"We can't go away from this tournament being like 'oh we're World Series champions, we're Commonwealth Games champions', we want to have all three of those medals," she told reporters.

"We've definitely spoken about it, like everyone we want to win every tournament we compete in but we're not shying away from the fact that's our goal and what we're aiming towards.

"It would be pretty epic to be the first team to do that.

"The resilience they've shown since the disappointment of Tokyo and the way they've bounced back this year and the growth that they've had as a group of girls, it's just been a pleasure to watch them play and play alongside them."

The women are seeking a second World Cup having claimed the 2009 edition while the men have never won the tournament.

But they'll come in confident, having pipped their rivals to the overall World Series crown with bronze in Los Angeles, beating Samoa 21-7.

"We should take that confidence we've built through our performances on the World Series, we know we're capable of beating those top teams," men's captain Nick Malouf said.

"We are one of those top teams now.

"As good as the World Series (was), we really want to put a cherry on top for the season and that would be winning the World Cup this weekend in Cape Town."

The women open their campaign on Friday night (AEST) when they battle Madagascar in the round of 16, while the men kick off early Saturday morning against the winner of Hong Kong and Uruguay.
