England are hoping they can exploit that with Jofra Archer, even against an Australia side they know so well. Archer, who helped the hosts combat some unfamiliar faces in the Bangladesh side through his insight from the Bangladesh Premier League, will be looking to do the same against Steve Smith at Lord's on Tuesday.
England set about recovering from a harrowing 20-run defeat against Sri Lanka at Leeds on Friday that leaves their semi-final spot far from confirmed. Archer, along with England allrounder Ben Stokes, spent the Indian Premier League season with Smith as teammates for Rajasthan Royals.
Smith had a decent time of it in India, scoring 319 runs at an average of 39.87 ahead of his return to international cricket following his ban handed down to him by Cricket Australia for his part in the ball-tampering saga in March 2018. So far, he looks to have carried that form to the UK.
Since arriving with the Australia squad in March, he has struck 76 and 116 in warm-up matches against West Indies and England, respectively, continuing his form into the World Cup where he currently has 244 runs across six innings, averaging 40.66 with three half-centuries.
But as tournament leader for wickets along with Australian left-armer Mitchell Starc - both quicks on 15 wickets - the 24-year old is keen to ensure that friendship remains off the field. With the help of Stokes, he believes there are chinks in Smith's armour to relay to the dressing room. The sort of chinks that can only be picked up by training alongside someone.
"That's the thing," starts Archer, "when you play with them you pick up on things you won't normally notice when you're just playing against them. So hopefully me and Ben we can get together - I think we might bowl together at some point as well - so we probably know what to do when he's in."
A lot of guys probably don’t want to face me
There were no bragging points to carry over from the Rajasthan nets: Archer, for the most part, did not bowl against Smith. Generally, given the intensity of the cricket and the schedules, it is inadvisable for fast bowlers to go full tilt at their own batsman. "A lot of the guys probably don't want to face me or Oshane (Thomas) in the nets," said Archer with a wry smile.
Perhaps refreshingly, Archer is not someone to buy into the England-Australia hypetrain, which often can career into nonsense. That, in part, comes from a childhood rooted in the Caribbean. He appreciates the competitiveness but is confident he can be level throughout Tuesday's match and what further encounters he may be privy to this summer.
"It is a pretty intense game between them and for me I'm not too sure if it will affect me coming in without having experienced it before. It could be an advantage, me not being part of what happened before."
