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."
As the countdown continues for RWC2015, Tournament Chief Executive Debbie Jevans visited the Millennium Stadium to discuss preparations for the eight matches and reveal the positive news that 100,000 tickets for games at the home of Welsh rugby have sold in the last seven days.
Jason Harries is targeting a first win on the World Series circuit this season with Wales. The series returns to action this weekend in Dubai where Harries is part of a team hoping to build from its efforts in round one in October.
Wales skipper Jevon Groves says his side have addressed a few points from Gold Coast and aim to 'hit the ground running' in the next two rounds of the World Series, kicking off with this weekend in Dubai before heading off to South Africa next week.
Wales Sevens manager Steff Thomas is hopeful his side can build from a quarter-final spot in the opening round of the World Series in Australia when his side take part in the forthcoming double header in Dubai and South Africa.
