Prop Cian Healy is expected to miss the start of the 2014 RBS 6 Nations after undergoing surgery on his injured ankle on Wednesday.
Ireland were based in Auckland for last year's summer tour and trained at Mt Smart Stadium, where they will have their squad sessions this week.
Full-back Geordan Murphy said: "It's only a six-day turnaround. Training will be important this week, we've got to do a good bit of homework.
"We know the quality that Australia have and the style of play they have, so it's going to be a huge game for us."
The Ireland team and replacements to play the Wallabies will be announced on Wednesday at 1.15pm New Zealand time/2.15am Irish time.
