"The mentality is there to attack but they put a lot of pressure on us. I've been saying on this tour we're not going to back down from trying to play attacking rugby and we won't in Cardiff either."
Wales were dispatched 33-10 by the All Blacks but managed a couple of second-half tries, giving them 20 five-pointers from 12 tests this season.
The World Cup semifinalists have lost their past six tests and desperately need to win.
If they beat the third-ranked Wallabies, they will book a place in the second tier of teams seeded fifth to eighth for next month's draw for the 2015 World Cup.
But a loss would see them drop below eighth-ranked Samoa and ninth-ranked Argentina and into the third tier of teams ranked ninth to 12th, guaranteeing a tougher World Cup pool draw.
The No3-ranked Australians will keep their top-four spot regardless of the Cardiff result.
"We've got a big job to do. In our last game of the tour we want to finish well and make a statement and they'll be looking to do the same in front of their home crowd," he said.
One area Beale is keen to tidy up is his kicking after gifting the Italian back three with some counter-attacking opportunities in Florence.
