I am planning a trip to Perth, and I wondered whether I could get the kids passports renewed when I was there. Plus get the first Australian passport for my youngest. The kids won't be with me, but I figured it might be easier in Perth rather than go up to Australia house in London. They always make me drag the kids up there and it's a real pain.
I figured I could do it by post from Perth, or even go into the immigration office. Probably easier by post. Might even be cheaper.
