Wales could face the full might of Australia's All Blacks destroyers in Cardiff on Saturday.
Wallabies coach Robbie Deans has revealed a clean bill of health among his squad, despite the game's punishing nature in Hong Kong two days ago when Australia prevailed 26-24 in an epic encounter.
"We will pick what we deem to be our best line-up against Wales to hopefully perform and get a result," said Deans, after arriving in the Welsh capital on Monday.
"It appears we have come through the New Zealand game unscathed and have the potential to name an unchanged side, which makes a change.
"Continuity is starting to serve us. Those who played in Hong Kong have done their chances of being selected on Saturday no harm."
Australia crushed Wales 33-12 at the Millennium Stadium a year ago, but recent Test history shows it has not always been a happy hunting ground for the Wallabies.
They lost 21-18 in 2008 - Wales' only win from nine attempts against Tri Nations opposition under coach Warren Gatland, were held 29-29 two years before that and suffered a 24-22 loss in 2005.
"Confidence and belief are good if well-founded and well-applied," added Deans.
"If we were to make any presumptions about Saturday it would be to our disadvantage. The result (against New Zealand) will benefit the side - there is a fair bit of relief.
"But Wales played very well in New Zealand in the summer, far better than the scoreboard indicated. They played a lot of good rugby, but they did not get a lot of reward for it."
