James Horwill said the Wallabies are "very excited" about starting a new era under coach Ewen McKenzie.
With the McKenzie era having now begun, the Wallabies assembled in Sydney and set their sights on regaining the Bledisloe Cup.
And Horwill told reporters that the mood is good going into their opener against the All Blacks.
"The guys coming in here are very excited about the opportunity that's ahead of us," he said.
"It's a fresh start under a new regime and it's our turn to sink our teeth into it and get on with business.
"We don't have a lot of time to prepare for that first Test so we've got to get down to work pretty much immediately.
"Speaking to a number of players, they can't wait to get into camp and get stuck into it."
Horwill, who was captain of the Reds team which McKenzie guided to Super Rugby glory in 2011, said he was looking forward to the coach transferring his know-how to the Test arena.
"He's made it pretty clear that this is what he's wanted to do and I'm thrilled to see what he's able to do with the national side," he said.
"Everything's a little bit different in a Test team compared to a Super Rugby franchise, so I'm pretty keen to see the differences that he'll bring to the team."
