England boss Martin Johnson admitted Australia were worthy winners at Twickenham but insisted his side would learn from Saturday's 18-9 defeat.
"Overall they deserved to win but there were chances for us to do a bit more," said Johnson.
"We started very well but lost a bit of control near half-time.
"The team's only playing its first game and at times we needed to be a little bit slicker, but we'll be better for it physically and mentally next week."
Johnson, who was delighted to welcome back the "world class" Jonny Wilkinson and Lewis Moody after long-term injuries, was pleased with his side's defensive effort but less impressed by some of their choices in attack.
"In the second half Australia dominated to such an extent they're going to score points - eventually penalties or tries are going to get you," added Johnson.
It didn't feel comfortable at any stage but we blew a few opportunities and hopefully we will take those next time

"We kicked away too much ball, which gave it back to them a little bit too easily.
"I've said to the guys, we were playing a pretty battle-hardened team coming straight out of the All Blacks game and a Tri-Nations series and that probably showed.
"The southern hemisphere teams have proved pretty difficult to beat throughout the history of the game. It's not a modern thing, to beat them is always pretty tricky."
Toulon fly-half Wilkinson, who was playing his first Test for 18 months, was disappointed by the result but said it was a "fantastic feeling" to be back in action at Twickenham.
"Australia have played a lot of Test matches and they've been through a lot together," said Wilkinson.
"This is our first one - we needed a marker to find out where we need to go next. We're disappointed about some things but some things went well."
