Robbie Deans has foreshadowed a fast, furious and dramatic Tri-Nations decider which will bring the best out of his underdog Wallabies on Saturday night.

Coach Deans vowed Australia would relentlessly attack the All Blacks at a sold-out Suncorp Stadium in an attempt to break a seven-year Tri-Nations drought.

Not even giving a moment's thought to the last-start 53-8 humiliation by South Africa, the Kiwi mastermind said his men would play to the potential they've only shown in glimpses in his first year in charge.

"We've seen glimpses of it but this is a one-off encounter with everything at stake so I think you will see more than just a glimpse (on Saturday) night," he said.

"The key in this game is going to be (attacking) relentlessly because the All Blacks will be doing that. They will be attacking relentlessly for 80 minutes.

"But that's not something that daunts us, that's something that excites us.

"It will be fast, it will be furious, it will be physical and will be intense and there will be drama, there will be drama galore. It will resemble nothing that has gone on before."

The Wallabies have shown snippets of their best and worst against New Zealand this year, starting with a sublime 34-19 win in Sydney before collapsing 39-10 in Auckland.

An upset by the five-point underdogs would not only signal one of the biggest turnarounds in Australian Test history, it would keep them alive in the four-Test Bledisloe Cup series and clinch the Wallabies' first Tri-Nations title since 2001.

"We came up short in the intensity and physicality (in Johannesburg) and there's no doubt that's what's coming," Deans said.

"The All Blacks have got the Tri-Nations and the Bledisloe Cups. They have owned both of them for a long time and they're not going to let them go easily.

"We haven't had them for a long time and there's a message in that alone and that's the question we have to answer (Sunday)."

Aiding the Wallabies is a strong home-ground factor, particularly at Suncorp Stadium which the Australians regard as their favourite venue.

They've lost just once in Brisbane in the last 11 years, albeit 13-9 to the All Blacks in 2006, and have a 9-4 advantage over NZ in their last 13 matches on home soil.

Flanker George Smith, set for a crucial breakdown battle with NZ skipper Richie McCaw, underlined the obvious when he emphasised the Test was "hugely important for Australian rugby".

Not only has the ARU's trophy cabinet been relatively bare since 2003, Australia needs a fist-pumping triumph to rejuvenate the code.

The Wallabies were helped with inspirational flanker Rocky Elsom shaking off a virus to train strongly ahead of his farewell Test before linking with Irish club Leinster.

The twin selection of battering rams Stirling Mortlock and Ryan Cross in the Australian midfield suggests a direct game.

Winger Lote Tuqiri hoped significant advantage line gains would lead to more space out wide but Deans stressed Mortlock would show his wares as a converted ball-player.

"We won't be one-dimensional," Deans said. "If we come along and just crash-bash that won't be enough.

"To think that will be sufficient would be foolhardy, so there will be some subtlety as to where and how we attack, and we've given that a lot of thought."

The All Blacks have cleared reserve prop John Afoa to play after overcoming a shoulder injury.

The high-stakes clash will be preceded by a curtain-raiser between the Australian Schoolboys and Fiji U18s.

The young Australians were presented with their jerseys by their positional counterparts in the Wallabies side after being allowed in the inner sanctum to soak up a Test team address by 1984 Grand Slam-winning skipper Andrew Slack.
