Australia fly-half Bernard Foley has claimed that opposite number Dan Biggar will be a huge threat in the Rugby World Cup Pool A decider with Wales on Saturday.
Both sides have already qualified for the quarter-finals, but the game at Twickenham will decide who wins the group.
The 25-year-old Ospreys man stood out in the Dragons' wins over England and Fiji, landing every kick at goal in a 36-point tally.
Foley told BBC Sport: "The way [Biggar] controlled the games has been outstanding, and his goal-kicking has spoken for itself.
"The way Wales use their backs to get on the front foot... and their forwards are just tireless as well, so it's going to be a really good contest for us, a great challenge."
The Wallabies will take a 10-match winning run against Wales into Saturday's encounter.
