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.
