Perth Airport has two domestic terminals side by side about 12km (7.5 miles) from the Perth CBD, while the International Terminal is about 17km (11 miles) away from town. The airport has seen a huge increase in passengers in recent years, so if you're travelling at peak times, be prepared for crowds and queues.
Although the airport's facilities have been criticised for being outdated and run-down, there is more than enough by way of restaurants, shops, baby-changing facilities, prayer rooms and other standard facilities so that your stay at the airport should be fairly enjoyable and uneventful.
Perth itself is isolated in a vast and empty stretch of Western Australia. The city is quiet and safe, with miles of spectacular, uncrowded beaches close by. If you have time, head for the zoo in the CBD, where kangaroos are allowed to hop right up to visitors.
