Australia captain Steve Smith says his team are confident they can counter India's quality spin attack in their Champions Trophy semi-final in Dubai on Tuesday.

Adam Zampa led the rout with figures of 4-12 as the outclassed Namibians were bundled out for just 72 off 17 overs.

That fourth wicket came off the last ball of his four-over spell when he bowled Bernard Scholtz comprehensively for a duck to become the first Australian male to reach the milestone of 100 T20 International wickets.

"Pleasing to get the win on the board. I feel refreshed and a lot of energy," said Warner.

Most cricketers would argue that good preparations make for good World Cup campaigns but after an injury-plagued buildup and a string of other setbacks Australia spinner Adam Zampa might have a different take.

While Ponting has been impressed with the way India have gelled as a team, the former World Cup winning captain shied away from including any players from the host nation when asked to name his top three players of the tournament thus far.

The stellar show boosted Australia's chances of making the semi-finals with their fifth straight victory.

Australian spinner Adam Zampa admitted he "saw red a little bit" but insisted he was within his rights after attempting a controversial "Mankad" run-out in the domestic Twenty20 Big Bash League.

Leading Australian spinner Adam Zampa has Covid but is still available for selection for their Twenty20 World Cup match against Sri Lanka later on Tuesday in Perth, the hosts said.

Australia's search for a successor to Shane Warne is yet to bear fruit nearly a decade after he retired, so Adam Zampa is naturally wary about comparisons with the leg-spinning great.
