With raw tearaway bowler Shaun Tait blooded in a crucial Ashes cricket Test, the Wallabies are being called upon to follow suit and gamble on untried troopers in their Bledisloe Cup "dead rubber".

Respected coaches Chris Hickey and Alec Evans are urging a fresh injection of talent for the final Tri-Nations clash against the All Blacks at Auckland's Eden Park on Saturday week.

Australian Under 21 coach Hickey called for Eddie Jones to relent from picking George Smith or John Roe at No.8 and instead give consistent Perth-bound Brumbies back-rower Scott Fava an overdue Test opportunity.

Queensland forwards coach and former Wallabies assistant Evans has meantime gone into bat for 20-year-old, 110kg back Lloyd Johansson to be a shock starter at inside centre.

With little else to be lost after four straight Test defeats, the well-respected pair believe the time is right for Jones to experiment and find an uncut gem with the 2007 World Cup looming on the horizon.

"Sometimes you have to be prepared to take a little bit of a gamble," Hickey said.

"It's a little bit like Tait in the Test match against England.

"A (dead) Test like this would be a good opportunity to try a few things.

"Look at Scott Fava, he's been the form No.8 in the Super 12 for the last few years but hasn't ever got a chance in Test rugby.

"Now we're in a position to have a look at a few players, they should be given a go."
