Pat Cummins says Australia are yet to play the “complete game” at the Cricket World Cup, despite their 33-run victory over defending champions England.

Adam Zampa took 3-21 to bowl England out for 253, being dismissed inside their 50-over allocation for the fifth match in a row after a 75-run partnership from Steve Smith and Marnus Labuschagne helped Australia set a total of 286.

Australia, having lost its opening two matches to India and South Africa, are now on a five-game winning streak at the tournament.

With matches to come against Afghanistan and Bangladesh, the five-time champions are odds on to make the semifinals.

“It’s been great. The boys have played brilliantly, every game we’ve found a way to win,” Cummins said at the post-match presentation.

“I feel like every game we’ve improved a little bit. I still don’t think we’ve played the complete game but we’ve had different matchwinners.

“We have a lot of pride.

“We knew at the start of the tournament we weren’t at our best.”

Cummins paid Zampa particular credit, with the leg spinner again controlling Australia’s bowling innings with another assured performance, as well as scoring a rapid 29 off 19 balls to help drive up Australia’s total.

With Australia almost certain to make the semifinals, Zampa said the best was yet to come.

“I hope so,” Zampa said when asked if Australia could yet improve at this World Cup.

“We put on a really competitive total, but it was going to be tough to defend.

“The ground felt really dewy, really wet. Length control, attacking the stumps, trying to guess what the batter was going to do was really important.

“The ball has come out as well as it ever has.”

With 19 wickets at an average of 17.15, the 31-year-old is now the leading wicket-taker at the World Cup.

“Adam Zampa’s been bowling beautifully,” Cummins said.

“He scored 30-odd, took a hanger out there, he’s a match winner. You always feel he’s close to a wicket.

“Maxy [Glenn Maxwell] and Mitchy [Mitchell Marsh] are going to be back at some stage.

“We’ve got a squad where everyone can perform if they need to.”

For England though, the inquest will now begin on what has been an atrocious title defence in India.

The defending champions and reigning T20 World Cup winners have lost six games for the first time in a single Cricket World Cup and remain rooted to the bottom of the ladder.

“I feel like we are having the same chat after every game at the minute,” a crest-fallen Jos Buttler said.

“There were improvements again today. We got back to more like how we can play but still short of it to lose by 30-odd.

“It certainly feels like a low point. I’ve had a few but definitely as a captain.

“To be stood in this position having arrived in India with high hopes is incredibly tough and disappointing. It hurts a lot.

“We haven’t done ourselves justice.

“Coming into the tournament we fancied ourselves to have a real go and push whoever it was going to be all the way.

“We’ve let ourselves down. We’ve let down people down at home, who support us through thick and thin and we wear that on our own shoulders.”
