Will Genia proved a constant threat in the first Test against Wales.
Australia's chief architect of Wales' downfall in the first Test, Will Genia, has demanded the Wallabies raise their game if they are to deny Rob Howley's men victory in the second Test at Etihad Stadium tomorrow.
Genia was in sensational form in last weekend's 27-19 victory at Suncorp Stadium but he is fully aware Wales will be gunning for revenge to take the three Test series into a series decider in the third and final Test.
"We understand we can't play the same way we did last week - we've got to be better if we want to win," Genia said.
"They're going to be better. We've made a huge point of that and we really emphasised that at training."
While Wales have made four changes in their bid to level the series, Australia will field an unchanged line-up in Melbourne.
"The consistency and cohesion within the structure of our attack worked really well," Genia added. "You have the same players inside and outside of you and knowing that it worked last week, you have confidence in the group and what we've done."
Wales assistant head coach Rob Howley has already proclaimed his side will have to quell the threat the diminutive halfback poses, but Genia is unfazed by the prospect of having a target on his back.
"I'll just go out there and do my job as best I can. If there is extra attention you've just got to deal with it," he said.
"I think an area where they will target us is probably our breakdown. They'll look to slow the ball down a little bit so that we don't get the momentum we had last week.
"We've had a big emphasis on that at training this week."
The GB7s women's squad is currently training at Wales' Centre of Excellence where assistant coach Richie Pugh tells WRU TV's Graeme Gillespie some 'tough calls' will have to be made when it comes to finalising the 12 spots for Rio's Olympic Games.
Wales U20's Billy McBryde is looking forward to starting his first game against New Zealand this afternoon in the World Rugby U20 Championship where his side are looking to gain revenge from last week's pool defeat to the Kiwis.
