A lot of chemists in Oz take passport photos as well as many Kodak or other processing outlets, so I wonder if places like Boots would or at the very least there must be Kodak shops in major centres. The criteria is very strict for passport photos so taking them yourself would be risky as it would delay your application if they get rejected.
Your supposed to look like a crim in your passport anyway, so the customs official can stare at you and make you squirm and feel guilty even though you're perfectly innocent, it's how they get their kicks!

Sorry...it's late and I'm just adding my useless two cents worth to pass a bit of time of day because it's nearly time to go home.
