Fuel Filter does not need to be changed at the same time of a oil change. Recommended change for Fuel filter is between 50-60k miles. Oil change recommended between 5k-15k (heavily debated - I change mine every 7.5k and new filter in between changes)
As for buying oil/filters check online. A lot the places I use are in the US so I am not sure how much shipping would be to Australia.
