Wallabies coach Robbie Deans says starting well in the inaugural Rugby Championship is a big priority as he contemplates back-to-back games against the world champion All Blacks.

Australia host New Zealand in Sydney on August 18 on the opening weekend of the four-team tournament and face the All Blacks again in Auckland seven days later.

Should they lose both games, not only would the Wallabies' decade-long Bledisloe Cup drought be extended but their quest for the Rugby Championship crown would be on life support.

The Wallabies enter the tournament as the last Tri-Nations champions, but remain ranked second in the world behind the All Blacks.

Deans was adamant New Zealand's World Cup win last year would not be an excuse for Australia to settle for second spot.

"There's no wriggle room. You enter every game to win it," said Deans on Monday at the announcement of his first train-on squad for the Championship.

"We're starting in the deep end and two fixtures back to back against the All Blacks.

"That's going to be a big priority for us, starting well."

Deans said the June Tests gave a good indication of what to expect from the 2012 All Blacks under new coach Steve Hansen.

Ireland went desperately close to securing a first ever win over the All Blacks in their second Test but copped a belting as the Kiwis responded in the third match and swept their three-Test series.

"The Irish got close to them and had a great opportunity in the third outing to show how close they were, or possibly get a result, and they got the message that the All Blacks not only consider themselves to be No.1 but are No.1," said Deans.

Deans's 27-man train-on squad comprises players from all Australian Super Rugby franchises except the Queensland Reds who are involved in the finals series beginning this week.
