Australia centre Adam Ashley-Cooper insists the British and Irish Lions have yet to see the best of the Wallabies in the Test series so far.
Ashley-Cooper scored the only try late in Saturday's second Test in Melbourne as Australia secured a 16-15 win to level the series and set up a decider in Sydney this weekend.
There have been suggestions that the Melbourne game represented a grand final for the Wallabies but these have been dismissed by Ashley-Cooper.
The 29-year-old said: "I think we've got a lot more in us, I thought the game on Saturday wasn't of great standard.
"We made a lot of improvements from game one, but we certainly feel we've got a lot more improvements to make.
"I think we didn't allow them through our defensive line once. I think they had zero line breaks.
"That's a really good stat and a good reflection of how we work defensively. I think for us a lot of improvement can be made in the backs.
"Possession was a bit of a issue. We need to hold onto the ball more.
"We've got too many threats in the back-line to waste, so we're hoping to get the ball into the wider channels this week."
Ashley-Cooper reckons the Lions might now be feeling the effects of a tough tour at the end of a long season but is unsure whether that will be an advantage to Australia.
"They've had some physical encounters with all the Australian provincial teams, so no doubt they are feeling it mentally and physically," he said
"But we certainly don't see that as an advantage or a distraction. We've got two games under our belt and we're feeling really confident out of the win on Saturday."
