England coach Trevor Bayliss has let it be known that he is displeased with a group of players who chose to act irresponsibly on the first night of the tour.
It emerged during the first Test that an allegedly intoxicated Jonny Bairstow attempted to headbutt Cameron Bancroft in a Perth night spot.
England have been subjected to intense media scrutiny on this Ashes tours after Ben Stokes was suspended for his part in an alleged street brawl in Bristol after an ODI.
The Bairstow incident has since been brushed off by both parties and downplayed but the coach remains livid.
Bayliss said after England lost the first Test by ten wickets on Monday:"We can't put ourselves in these situations however small they are.
"They have only got themselves to blame.
"Any team will take any opportunity to get stuck into the opposition, make them feel uncomfortable wherever possible. If you put yourself in that situation you are fair game, we have to be careful we don't do that in future."

Bayliss had earlier said there would be no booze ban on the tour but that and tighter curfews now seem likely.
The coach would add: "There will probably be a tightening up of curfews.
"Players put curfews on themselves around matches, then it's up to me to say we haven't got a game for a few nights, you can head out but obviously not be stupid.
"That's the disappointing thing, we make dumb decisions at different times.
"We have to be smarter.
"Most people like going out at night and having a couple of quiet ones. You have got to be careful you don't do anything stupid. If that means not having anything to drink then so be it."
The ECB have not yet commented on possible sanction for Bairstow.
The second Ashes Test gets underway in Adelaide on Saturday and will be the first ever pink ball day/night match between Australia and England.
