Wales hooker Richard Hibbard believes battering Australia in the physical exchanges will be the key to victory in Saturday's Test in Cardiff.
Hibbard was one of the British and Irish Lions' heroes in their 41-16 series-deciding victory over the Wallabies in Sydney earlier this year and was at the forefront of his side's physical onslaught in that Test.
The Ospreys stalwart believes a repeat of those tactics will do the trick for Wales this weekend.
"We were physical, we battered them for 60 minutes and that was the end of it, they couldn't survive after that," said Hibbard.
"We have to bring that ferocity again.
"We definitely want to win this, we're going to win this and we have to bring the intensity from the off and the physicality right across the park."
The 29-year-old is among several Wales players who can claim to have beaten the Wallabies in their careers thanks to their victories with the Lions. And he believes that will give his side a mental edge over Australia.
But he is not underestimating the visitors and acknowledge that Australia were not the same side under new coach Ewen McKenzie.
"They played well in the [Rugby] Championship and seem a different team over here, their confidence is high," added Hibbard.
"It will be a tough one, probably the toughest of the last four years."
Australia's forwards have improved as their tour progressed after they were criticised for poor performances in the scrums during the Lions series.
Hibbard expects a different Wallaby pack to take to the field on Saturday.
"They have come under a lot of fire over the years but it's one of their weapons now," he said.
"What they did to Ireland [two weeks ago] was impressive. You can't say they are a weak pack, they never were, it was a myth.
"They're a strong unit and it will be a big challenge."
