Coverage: Ball-by-ball Test Match Special commentary on BBC Radio 5 live sports extra, Radio 4 LW, BBC Sport website and app.
Of the 16 players in England's squad, seven were involved in the Ashes, while only four played all five Tests.
One thing they do have in their favour is a relatively settled unit.
"Everyone has been playing plenty of cricket so it won't be a case of England being rusty".
"Whatever's been thrown at me, I feel like I'm confident enough to play my shots, no matter what the standard", Harvey said.
In his first top-flight senior game, the 17-year-old lifted his fourth ball over third man for six off Wood and struck three more maximums before Rashid had him stumped for 59. However, with the coloured jersey on, the English team will not let Australians take the charge from first match itself.
"I know he felt as if he didn't quite have the rhythm but, certainly today, his control was magnificent", Morgan said.
While the likes of Joe Root, Moeen Ali, Jonny Bairstow and Chris Woakes all head into Sunday's first one-day worldwide in Melbourne bearing the bruises of the Test reverse, others are bringing a fresh dynamic.
The rejig has been caused by the absence of Stokes and the return of Hales, who was suspended at the end of last summer after both were caught up in the street fight in Bristol.

Trump had certified the deal twice before, and senior officials have grudgingly said Iran is complying. Trump had faced a Friday deadline to decide on whether to waive the sanctions.
"We want to get the feeling around the one-day group a lot more positive and upbeat in order to play this brand of cricket".
"You can't replace Ben Stokes, but you can go some way to filling his spot with the variety England have got in their limited-overs set-up", said Taylor.
But there is already disquiet in some quarters that with so much emphasis on how best to prepare for the next Ashes series in Australia in 2021, two years of planning will effectively be put in place by a coach who will not be there to see the job through, and whose successor might have different ideas anyway. The all-rounder claimed 2-28 from 10 overs in the warm-up victory over a Cricket Australia XI this week. Chris Woakes has been Mr Reliable.
Eoin Morgan has leapt to the defence of England head coach Trevor Bayliss, praising him for lifting the pressure off the squad.
Bayliss led England to the World T20 final and to the Champions Trophy semi-final and has overseen significant improvements in the one-day game. "I'm just looking forward to getting in amongst it". "As does Paul Farbrace - he's very positive and they are a good combination".
Maxwell had a coffee with Smith on Friday after the Australian skipper publicly called on the dynamic allrounder to "train smarter" and focus on substance ahead of flair.
"That gave me a fair bit of confidence", he said. "It is astonishing - he would be my first player on the team sheet".
