Australia’s white-ball stars are in top form ahead of the World Cup.

Australia has issued a warning ahead of the ICC Men’s Cricket World Cup by sweeping South Africa 3-0 in their T20I series in Durban.

The five-time World Cup champions completed the series sweep with another dominant performance on Sunday, cruising to a five-wicket victory behind opener Travis Head’s career-best T20I innings of 91.

Head was named Player of the Match after hitting eight fours and six sixes in 48 balls as Australia chased down South Africa’s respectable total of 190/8 with more than two overs remaining.

Head was named to Australia’s preliminary World Cup squad for this year’s 50-over showcase last month, and his maiden T20I half-century against the Proteas demonstrated that he could play a significant role in the event.

“It’s nice to be back and contributing,” said Head.

“There have been few opportunities in this format for a long time.” I’d been struggling to find my tempo and how I wanted to approach things at the top.”

Mitch Marsh was named Player of the Series for his 186 runs, and the Australia captain could play a key role in his team’s World Cup push in India if he can replicate his hard-hitting form against South Africa.

Marsh’s first series as Australia’s new T20I captain, and the 31-year-old was overjoyed that his team could cruise to a series victory.

“I’m really proud of a pretty young group coming over here and winning the series 3-0,” Marsh said.

“It was a fantastic team effort.” We had done our homework and were ready to play.

“We had a little bit of luck at times, but as a team, we had a really positive mentality.”

While South Africa missed pace duo Kagiso Rabada and Anrich Nortje throughout the series, white-ball coach Rob Walter made no excuses for his team’s poor performance.

“There’s no getting around it – their batting ability was superior to what we had to offer with the ball,” Walter said.

“We learned a hard lesson about not executing our skills.” It was a wake-up call for the bowling unit.”

The teams will now get some valuable 50-over practice ahead of the World Cup when they play a five-match One-Day International series in South Africa over the next two weeks. The first match of that series will be played on Thursday in Bloemfontein.
