The 36-year-old goalkeeper is keen to become the longest serving Australia international and wants to see his country qualify for the 2010 World Cup finals.
He said: “I haven’t really put a timeframe on it, I’m just going to take it as it comes.
“My main aim is to qualify for the World Cup and then go to the World Cup and have a successful tournament again like we did in 2006.
“I’d like to set ourselves a goal to even better that.
“It’s one thing saying it and another thing doing it, but you’ve got to set yourself high standards and I believe that we can achieve those goals.
“First, let’s get there and once we get there we can talk about what the future holds for us as a team or for me as an individual.”
