LEIGH Halfpenny hopes his right boot will make all the difference at the Millennium Stadium this afternoon – and if the Australians do suffer from his unerring right boot then it will be down to the wise advice of a Welsh points machine rather than his English kicking coach.

Halfpenny, man of the series when the Lions beat the Aussies last summer, has gone 16 games without success against the three southern hemisphere big guns with Wales.

Given that the average margin of defeat to the Wallabies since 2008 is six points the chances are that the full-back could be the difference between a narrow defeat and a tense victory.

Halfpenny is notoriously diligent on the training paddock and despite his move to Toulon, where he receives the pearls of wisdom of England World Cup winner Jonny Wilkinson, it's still Wales' all-time leading points scorer who remains his mentor.

"Jonny's there for one week every month and there are skill sessions where I work on my passing with him," said the 25-year-old.

"But in terms of kicking I've worked a long time with Neil Jenkins. He's brought me through from the academies right up to international level, so you don't want to listen to too many voices because we have found a way that suits me.

"I didn't want to change that. So in terms of kicking, I've worked with Jonny, but I haven't changed anything."

Halfpenny, whose Wales tally of 395 is dwarfed by Jenkins' 1,049, doesn't seem bothered by the toughest of touchline kicks but insists he isn't immune to the pressure.

"Inside my heart is thumping like mad," he said. "The boys work hard getting the penalties and scoring tries, so, as a kicker, you want to reward your team-mates with the extra two or three points that they've worked so hard for.

"It's huge pressure but at the same time it's a privilege for me."

Halfpenny has experienced a fair share of last-gasp disappointments, notably in 2012 when his last-ditch tackle on Dave Dennis saw him out cold for Kurtley Beale's dramatic winner in Cardiff.

"We've been there or thereabouts pretty much every game against them. It's about that concentration for the full 80 minutes," he said.

"In a number of the games, Australia has beaten us on the last play or with a few minutes left so we can't switch off for one second."
