Call it the "Cheik list": the many things the Wallabies coach is adamant his team can still improve; the rugby world expects New Zealand to lift for the Bledisloe Cup decider in Auckland on Saturday after their loss in Sydney, but Michael Cheika has emphasised his side can also play much better.

"We've got such a big margin for improvement," Cheika said on Tuesday. "We're still making a lot of mistakes and our work rate can improve a lot; our physicality can improve a lot. I think that there's a lot of areas that we can improve."

Cheika is looking for daily improvement through this week so his side will be competitive at Eden Park and avoid a repetition of the 2014 fixture in which the All Blacks thrashed Australia 51-20 in Auckland a week after holding the 12-12 draw in Sydney.

"There will be a certain expectation over there that they will give it to us," Cheika said. "That's what the perception will be from their home crowd. They will be expecting that especially after last year. The way it is, is that we've just got to go out there and do our absolute best and make our Australian people proud of the way we play."

Cheika revealed he was considering changing his winning line-up without answering whether that might include the halves. Replacements Nic White and Matt Toomua were key figures in Australia's decisive late surge after starters Nick Phipps and Bernard Foley had struggled to make an impact.

Cheika suggested changes wouldn't be purely based on form as he continued to look at different combinations ahead of the Rugby World Cup in September and October.

"We'll have a look at what the weather might do over there as well and just see what the best combination for us is."

Cheika said he was keen on rotating players in and out of the line-up.

"I know that's traditionally not what people like, but I like the idea because you might lose a guy in a match or you might get an injury," Cheika said.

Israel Folau didn't do contact work because of bruised leg, but Cheika said he was fine, and prop Scott Sio finished the session early after getting a poke in the eye.

Matt Giteau was given an extra day's recovery and didn't train on Tuesday morning, with Cheika joking it was due to a "bit of old age".
