"I'm looking forward to it," said James, who played in six of the seven matches during his country's triumphant World Cup campaign.
"For me, I'm just grateful for another opportunity to go out there and show what I can do.
"I'm just going to go all out and try to perform in the next two Tests."
James, who will line up against Matt Giteau this weekend, knows his side need to improve on the recent defeat to New Zealand, even if he is slightly unsure as to how Australia will play on Saturday.
"We've got to be patient and put a few phases together.
"Last week we were too rushed and kept trying to score off first phase. If we can be patient and cut out the errors, we should do well.
"It's difficult to analyse the Wallabies at this stage because they can change their game week in and week out and so it's hard to know what to expect.
"You always want to judge yourself against the best and in the Tri-Nations you are playing against the two best fly-halves every weekend and it is something very exciting."
