Giteau's contract with the ACT Brumbies and the ARU comes to an end after this year's World Cup, with the 28-year-old playmaker already heavily linked with a big-money move abroad.
Giteau could play a huge role for the former world champions when the Lions come calling in two years time but his refusal to commit his future to his country is only heightening speculation that he could be tempted to move overseas.
But while the 91-times capped former scrum-half knows speculation will continue unless he commits to the ARU, he is adamant that his concentration will be on playing for club and country rather than worrying about his future.
"For me, it's about worrying about this year and seeing how my enjoyment and things like that go. I'll see if I need something fresh and wait to see how this year pans out," Giteau told the Sydney Morning Herald.
"Talk and speculation about my future doesn't worry me. I want to be heavily involved in both the new season with the Brumbies and the Wallabies because it's a World Cup year as well.
"I feel really good. I've got no injuries and on the tour I probably didn't play as many games as I have previously so that probably freshened me up.
"For me the hunger is still there. I've been doing training before I'm due back and that's how you know the hunger is there. I think if (the Brumbies) can play some good rugby, we're as good as anyone.
"I'm just focussing on the Brumbies and then whatever happens, happens."
