A lot of the pre-Ashes talk was dominated by Ben Stokes and whether or not he'd be eligible for England Down Under.
Stokes, who is now playing for Canterbury Kings in New Zealand, and Hales have not been in action for England since September 24 after they were declared unavailable for global selection until further notice.
"Selectors were given clear guidance to name their strongest squad and have made their selections accordingly".
England do not intend to rest any Test regulars such as Joe Root, Bairstow, Moeen Ali or Chris Woakes in the ODIs against Australia but may consider a break during the Twenty20 tri-series which follows.
England cricketer Ben Stokes has been playing for Canterbury while waiting to learn if he will be charged over a street fight incident in Bristol.
"Alex Hales will now be considered for England selection following confirmation that he is no longer a suspect in relation to an incident in Bristol in September", the European Central Bank said in a statement on Monday night.
Bayliss said: "The two openers we had did very well, and it would be hard to go against (them). We've got to adjust to that at some stage". "I can't see any changes there personally".
Also back in the mix lower down the list is fast bowler Mark Wood, returning from his heel injury. There were murmurs within the camp that senior players including Joe Root, Moeen Ali and Bairstow would be rested for the ODIs but Bayliss meant to hold on to the core in preparation for the 2019 World Cup. We won't know it actually until it comes along. "Hopefully, if all goes to plan, they'll play these five Test matches and the five one-dayers as well and then we'll look at giving them a break".
"I've got absolutely no idea". Whenever he comes back that's going to be a bit of a circus for sure.
After making just two runs and had figures of 0-49 off nine overs in a defeat to Otago, he got off to a promising start in his second match.
