Ian Bell has admitted England had not scored enough runs in their first innings of the First Test as the Ashes got under way in Brisbane.

Warwickshire batsman Bell did his best to lift England to a competitive total with a classy 76, but the tourists were eventually dismissed for 260, with Australian fast bowler Peter Siddle boasting figures of six for 54, which included a stunning hat-trick.

"It was certainly under par," said Bell. "But we have to give credit to Siddle. He bowled a brilliant spell.

"It was the right decision to bat but it did a bit today."

Bell was glad to have taken his form from the warm-up matches into the Test series and paid tribute to England batting coach Graham Gooch for helping him improve his batting.

"It was nice to get runs on day one of an Ashes series and hopefully we come back tomorrow and have a good day.

"The experience I have gained over the last couple of years I have put into my game recently and hopefully I can carry on this form for a while now.

"Graham Gooch has really helped my cricket. He has put some things into my game and hopefully I can carry on like this with my form now."

Asked if he was content to bat down the order or coveted another chance at number three, Bell replied: "I am enjoying my role at number six.

"My record isn't great at number three. It is something I would like a shot at again but I have to work my way up."

Siddle, meanwhile, hailed an "amazing" 26th birthday as he helped his side take control of the First Test.

The Victorian became the 11th Australian to take a Test match hat-trick when he had Alastair Cook edging to slip for 67, then had too much pace for both Matt Prior and Stuart Broad to leave England struggling on 197 for seven.

"It's obviously good to wake up to your birthday in the morning and obviously to have that happen has been amazing, and hopefully the start of a good Ashes for us," a delighted Siddle said.

"The plan was pretty similar all day, to pitch it up, make them play, be patient and consistent with those lines.

"I got Cook and Prior with two balls like that and I think the third was a bit of adrenaline from the crowd, I bowled it fast. It didn't really come off as the ball I wanted but I got him so there's nothing more I could ask for."

Siddle was a touch concerned his big moment could have been ruined when Broad referred his hat-trick wicket upstairs.

"A little bit," he admitted. "I knew it was most likely in line so I was happy with it."
