Australia coach Darren Lehmann accepted his side had been second best throughout the Ashes series but insisted they had learned plenty of lessons ahead of the return series, which begins in Brisbane on 21 November.
The fifth Test at The Oval ended in a draw after Michael Clarke's enterprising declaration almost allowed England to chase down 227, with bad light ending the day four overs early to leave the hosts celebrating a 3-0 series win.
"What we've got to do is play better," said Lehmann. "England outplayed us 3-0. We had our chances in the series and didn't take them.
"Our batting's got to improve, we know that. The exciting thing for us is we are on our way up and now we've got to keep improving.
"From our point of view we've just got to keep learning those lessons and get better at home."
Lehmann said of his first series as coach: "It's been a great ride, I've liked every minute of it.
"We have to make sure we improve on the field and off it."
Australia skipper Michael Clarke played down a confrontation with umpire Aleem Dar as only a late stoppage for bad light prevented him becoming the first Australia captain to lose a series 4-0 in England.
"I can't remember what I said to him but I remember Aleem touching me, and I asked him politely to not touch me because if I touched him I'd be suspended for three matches," said Clarke.
"I just asked the question why we haven't got the meter out there and it took a few overs to get it out. That's all I can remember, coincidentally.
"From my point of view I have no issue, I just know a player is not allowed to touch an umpire...but for me personally I have no issue with it."
