Mitchell Starc revealed a bantering fan inspired his hostile spell against England at Lord’s on Tuesday.
Starc's wife Alyssa Healy, who is a key member of Australia Women's team, shared the incident on Twitter, claiming an England supporter had fired up her husband with his banter before the game.
Starc confirmed he had been targeted but insisted the jibes weren't really personal.
"I was still half-asleep. It was some bloke in a suit, having a go at my strapping tape and having a go at my bowling. I was just hungry," he said after taking four wickets in Australia's 64-run win over their old rivals at Lord's.
"He was just having a laugh at my strapping tape and what I was eating. I had a few poached eggs, three I think.
"It's all been good fun throughout the tour around the crowds and at the hotel. It's just part and parcel of a World Cup."
Starc believes Australia’s thumping win was the perfect preparation for the World Cup knockout stages.
Australia dominated England right from the start to thump the tournament favorites and Starc expects the impressive performance to hold them in good stead later on in the tournament.
"It's an interesting one. It's a World Cup. I guess playing at Lord's today, where the final is going to be, is great for us," he said.
"Obviously we are into the semi-finals now so we have to make sure we play some good cricket, finish as high as we can in the group and hopefully get into that final."
Starc urged his team not to hold back and do well against New Zealand to make a strong statement once again.
"Now we've got to play New Zealand, which is going to be tough for us," he said.
"They have gone under the radar. No-one has really spoken about them too much but they keep winning games.
"They are playing some fantastic cricket. Kane Williamson is obviously their lynch-pin and they have good bowlers who swing it. It's another big game."
