Ever looked at a map of Australia and thought you had it all figured out? Big red middle, green edges, one lonely triangle at the bottom called Tasmania.
Honestly, most people stop there. They see the "Island Continent" and forget that it’s actually an archipelago on steroids.
We’re talking about 8,222 islands tucked within those maritime borders. Most of them don't even have a name on your standard Google Map. You’ve got everything from sub-Antarctic rocks where the wind literally tries to peel your skin off, to tropical specks in the Timor Sea that look like a Windows screensaver.

The Numbers That Break the Australia Map
If you look at a high-res Australia map and islands data from Geoscience Australia, the sheer scale is kinda overwhelming.
Western Australia is the secret winner here. It’s got 3,747 islands. Queensland comes in second with 1,955. Even little old Victoria has 184.
The weirdest part? If you took all the islands (excluding Tasmania, because it’s a whole state) and mashed them together, they’d cover an area about half the size of Tasmania itself. That’s roughly 32,160 square kilometers of "extra" land just floating around the edges.
- Tasmania: The big one. 68,401 square kilometers of rugged mountains and rain.
- Melville Island: Way up north. It’s huge—nearly 5,800 square kilometers—but most people couldn't point to it on a map.
- Kangaroo Island: Down in South Australia. It’s basically a zoo without fences.
- Groote Eylandt: In the Gulf of Carpentaria. Known for manganese and incredibly good fishing.
Why Your Map Probably Lies to You
Standard maps usually cut off the "External Territories." These are the outposts that make Australia’s maritime jurisdiction absolutely massive.
Take Christmas Island. It’s way closer to Indonesia than Perth. It’s famous for the red crab migration, but on a typical map, it’s just a tiny dot—if it’s there at all. Then you’ve got the Cocos (Keeling) Islands. These are 27 coral islands that look like they belong in the Maldives. They’re actually an Australian territory, sitting 2,750 kilometers northwest of Perth.
And don’t even get me started on the Heard and McDonald Islands. They’re about 4,100 kilometers southwest of Perth. It’s basically a volcanic wasteland in the Southern Ocean. No one lives there except for seals and penguins, but it’s still "Australia."

Exploring the Great Barrier Reef's Secret Spots
When someone says "islands in Australia," you probably think of the Whitsundays. Fair enough. Hamilton Island is great if you want a golf cart and a cocktail.
But there’s a whole world beyond the tourist hubs.
Lizard Island is a granite peak sitting right on the Great Barrier Reef. It’s officially a national park. The Dingaal people call it Jiigurru. It’s the kind of place where you can grab a dinghy, a picnic basket, and find a beach where the only footprints are yours.
Further south, you hit K’gari (formerly Fraser Island). It is the world's largest sand island. It’s the only place on the planet where tall rainforests grow out of sand dunes at elevations over 200 meters. Driving a 4WD along 75 Mile Beach is basically a rite of passage for any Aussie traveler. Just watch out for the dingoes. They look like dogs, but they definitely aren't.
The Remote Outliers
If you want to get really weird with it, look at Lord Howe Island.
It’s a tiny crescent in the Tasman Sea, a two-hour flight from Sydney. They only allow 400 tourists at a time. Total. It’s home to the southernmost coral reef in the world and a mountain called Mt Gower that looks like something out of Jurassic Park.
Basically, it’s what Hawaii would look like if humans hadn't paved half of it.
The Cold End of the Map
Most people think of Australian islands and think "thongs and sunscreen."
Tasmania proves them wrong.
The Bass Strait, which separates Tassie from the mainland, is one of the roughest stretches of water on the planet. It’s shallow and nasty. But once you cross it, you find islands like King Island and Flinders Island.
King Island is famous for two things: beef and cheese. The grass there is so salty and rich that the brie basically tastes like gold. Flinders Island is more rugged, full of pink granite peaks and shipwrecks. It feels like the end of the world because, well, it kinda is.
Expert Tip: If you’re heading to Tasmania’s satellite islands, don't expect a 5-star resort. Expect wind, wild seas, and some of the best seafood you've ever eaten in a shed.
Navigating the Map: Actionable Next Steps
Look, you aren't going to visit 8,222 islands. Nobody has that kind of time. But if you want to actually "see" the Australia map and islands properly, here’s how to do it without getting stuck in a tourist trap.
- Fly to Darwin for the Tiwi Islands: Go to Melville or Bathurst. It’s a completely different culture and geography than the East Coast. You need a permit, so plan ahead.
- Use the "Off-Peak" Strategy for the Whitsundays: Visit in June or July. The water is still warm enough, and you won't be fighting 5,000 other people for a photo of Whitehaven Beach.
- Book Lord Howe a year out: Because of that 400-person cap, it fills up fast. It’s expensive, but honestly, it’s the best island in the country.
- Check the Maritime Boundaries: If you’re a geography nerd, look up the "Exclusive Economic Zone" (EEZ) of Australia. It’ll show you why those tiny specks like Ashmore Reef actually matter for things like fishing rights and oil.
Download a specialized nautical map or use the Geoscience Australia interactive tools instead of just relying on your phone’s default map. You’ll start seeing the thousands of fringing reefs and islets that define the actual shape of the continent.
