Australia hold the Tri-Nations fates of Great Britain and New Zealand in their hands, but the Kangaroos are focussed purely on getting back into the winners' circle.
The Kangaroos watched the Kiwis' 34-4 thumping of the Lions from their Brisbane hotel but insist they are more interested in
achieving the two wins needed to reclaim the Tri-Nations title.
Australia are in the final after two wins over New Zealand to start the series and now play Great Britain in Brisbane on Saturday in a match that will decide their opponents in the final.
An Australian victory will ensure a re-match of the 2005 final with the Kiwis, while a Lions win will result in an Australia-Great Britain decider in Sydney on November 25.
The British would also carry a significant psychological advantage into the final should they qualify, having already beaten the home nation this series.
Kangaroos forward Andrew Ryan said Australia would treat next weekend's clash at Suncorp Stadium as a must-win.
"It's going to be a massive clash and win at all costs for both sides," said Ryan.
"It's just important for us after losing last week to try and get things back together, get things happening on the field and get the win.
"We were not really too concerned on last night's result, we knew we would have to play better than we did last week regardless and it's going to be a challenge no matter what happened.
"We've got two massive games to go and hopefully we will play well and get two wins."
But Ryan said it wouldn't be a complete disaster if they lost to the Lions - thereby avoiding another clash with the Kiwis, whom Ryan described as "impressive" in Wellington.
"It'd be good to get a win but it won't be the end of the world if we don't.
"I thought Lions captain Jamie Peacock was pretty good against New Zealand but they made a few errors they did not make last week.
"The Kiwis were pretty impressive. They were really intense and ripped in and it obviously showed on the scoreboard.
"Their intentions were pretty clear from the start.
"They've had a couple of weeks where it has been brewing up and they unleashed on the Lions."
