Matt Giteau was taken aback to learn that England's rugby chief had sent an apology to Australia's high commissioner in London after he and Wallabies captain Stirling Mortlock were booed and jeered at Twickenham.

RFU president Brian Williams wrote to high commissioner John Dauth apologising for the "bad manners" shown by England fans towards the Wallabies goalkickers during last Saturday's Test, which Australia won 28-14.

Despite England fans doing their best to put Giteau off, the sharp-shooting five-eighth slotted a record six penalties and a conversion from eight attempts, while Mortlock also nailed a crucial penalty from close to halfway.

Giteau said on Tuesday he had no idea an apology had been issued by the Poms, nor did he think one was necessary.

"It's pretty common. I think whenever you play at most stadiums, you generally boo the opposition," he said as the Wallabies prepared to take on France this Saturday in Paris.

"When you're kicking, you try to zone as many things as you can out. It wasn't something that I took personally.

"(But) I suppose it gives you a little bit more satisfaction when you do kick the goals."

Giteau, enjoying career-best form with the boot, said he'd be happy for crowds to continue jeering him if it helped him maintain his amazing strike rate this season.

The 26-year-old has landed 50 shots from 58 attempts in 2008, including 16 straight at one point, at a conversion rate of 86 per cent.

"I feel as though I'm striking the ball better and more consistently. That's the biggest thing," Giteau said.

"There's been times where I may have kicked well one week and the next week been a little bit inconsistent.

"This year, in particular, I've been really pleased with how consistent I've been."

Giteau said he hadn't altered his style this year and was merely practising what former Wallabies kicking coach and good friend Ben Perkins had preached during his stint with the national team.

"Rhythm and authority are the two things Ben taught me," he said.

"Things don't change a real lot. I think can get complicated at times. But it doesn't need to be.

"It's just being consistent and trusting your run-up. I suppose if you do miss a kick, it's very easy very to fall into a trap and change something straight away.

"But I think this year I've tried to focus on the same thing each kick and so far it's worked for me."
