There are around 8,000 islands off the Australian coast. Most you'll never set foot on, but a few dozen are worth booking a ferry, a flight, or in some cases a 4WD with deflated tyres. This site is a working guide to the ones that matter for travellers: how to get there, what it costs, what to pack, and what's actually worth doing once you arrive.
We started with the islands we know firsthand from Western Australia and have been working east. Each guide is updated when prices and ferry timetables change, which is more often than tourism boards admit.
