You’d think it’s a simple question. Most people just shout out "Six!" and move on with their day. But if you’re actually standing in the middle of Canberra or flying over the red dirt of the Darwin outback, that answer feels a bit thin. Honestly, the whole "how many states" thing in Australia is a bit of a trick question because it depends on whether you're talking about legal definitions, where people actually live, or those tiny islands in the middle of nowhere that technically fly the Southern Cross.
Basically, Australia has six states. That’s the official number baked into the Constitution. But then you’ve got these things called territories. There are ten of those. Most Aussies only care about two of them—the Northern Territory (NT) and the Australian Capital Territory (ACT)—but there’s a whole lot of weirdness happening in the others, like Jervis Bay or the frozen stretches of the Australian Antarctic Territory.
Australian states how many: The Core Six
When people ask about the states, they’re usually thinking about the big players. These six started as separate British colonies before they decided to team up in 1901. Each one has its own parliament and its own set of rules.
New South Wales (NSW) is the big boss in terms of population. It’s home to Sydney, the Harbour Bridge, and a massive chunk of the country’s money. It was the first colony, established back in 1788. If you've ever seen a postcard of Australia, there’s a 90% chance it was shot here.
Then you have Victoria. It’s the smallest mainland state but it’s packed tight. Melbourne is the heart here, and people take their coffee and AFL (Aussie Rules Football) way too seriously. It actually split off from NSW in 1851 because they found gold and suddenly became rich enough to want their own house.
Queensland is the "Sunshine State." Think Great Barrier Reef, humid summers, and a very laid-back vibe. It’s huge. If you’re driving from Brisbane to the tip of the north, you’re looking at days of travel.
Western Australia (WA) is basically its own country. It takes up a third of the continent. It’s so far away from the east coast that people in Perth sometimes feel more connected to Singapore than Sydney. Most of the country's iron ore and gold comes from here, keeping the national economy afloat.

South Australia (SA) is the wine capital. Adelaide is the main hub. Fun fact: it was the only state that wasn't started by convicts. They were "free settlers," and they’ll remind you of that if you ask.
Finally, there’s Tasmania. The island state. It’s cold, rugged, and beautiful. It’s often left off maps of Australia by mistake, which drives the locals absolutely nuts.
Why territories aren't states
This is where the confusion starts. Why isn't the Northern Territory a state? Why is Canberra in a "Territory"?
The main difference is power. States have their own rights under the Constitution. The federal government can’t just walk in and tell New South Wales how to run its schools or hospitals (usually). But territories are different. The federal parliament in Canberra has the "plenary power" to override territory laws.

The Northern Territory (NT) is massive but barely anyone lives there compared to the states. Because of that low population, it hasn't quite made the jump to statehood, even though they’ve tried.
The Australian Capital Territory (ACT) exists for one reason: Sydney and Melbourne couldn't stop fighting over who should be the capital. So, the government picked a spot in the middle of a sheep paddock, carved it out of NSW, and built Canberra.
The "Secret" Internal Territory: Jervis Bay
Hardly anyone mentions Jervis Bay. It’s a tiny slice of coast about three hours south of Sydney. Technically, it’s a third "internal" territory. Why? Because when they built Canberra inland, the government decided the national capital needed its own port and access to the sea. NSW handed over a bit of land, and now it’s a weird legal bubble that’s mostly a naval base and a stunning national park with some of the whitest sand you’ve ever seen.
The seven external territories
If you really want to win a pub trivia night, you need to know about the ones offshore. Australia owns a bunch of islands and a massive chunk of ice.
- Ashmore and Cartier Islands: Uninhabited reef islands near Indonesia.
- Christmas Island: Famous for millions of red crabs migrating across the roads.
- Cocos (Keeling) Islands: A tropical paradise with a very distinct Cocos Malay culture.
- Coral Sea Islands: Mostly just birds and weather stations east of the Great Barrier Reef.
- Heard Island and McDonald Islands: Sub-Antarctic, volcanic, and incredibly hard to get to.
- Norfolk Island: This place has its own history, settled by descendants of the Bounty mutineers.
- Australian Antarctic Territory: Australia claims nearly 5.9 million square kilometres of Antarctica. Most other countries don't officially recognize this claim, but we still run the research stations.
The weirdness of state borders
The lines on the map look straight, but the reality is messy. Take the town of Albury-Wodonga. It’s one community split by the Murray River. One side is NSW, the other is Victoria. During the COVID-19 lockdowns, this was a nightmare. People couldn't cross a bridge to go to work or buy milk because the state governments had different rules.

Even the time zones are a mess. In summer, Queensland doesn't do Daylight Saving, but NSW does. If you stand on the border in Coolangatta, you can literally walk across the street and gain or lose an hour. It’s a headache for businesses and anyone trying to catch a flight.
How many states actually matter for your trip?
If you're planning a visit or moving here, the "how many" question is really about geography. Most people stick to the "Eastern Seaboard" (NSW, VIC, QLD). But if you want the "real" Australia, you’ve got to head to the NT or WA.
The Northern Territory is where you’ll find Uluru and Kakadu. It’s the spiritual heart of the country. Western Australia is where you find the Ningaloo Reef, which is arguably better than the Great Barrier Reef because you can just swim to it from the beach.
Actionable insights for your Australian journey
- Check the rules: If you’re driving across borders, remember that things like fishing licenses, U-turn rules, and even school holiday dates change from state to state.
- Watch the clock: Always double-check time zones if you're traveling between October and April. South Australia is 30 minutes behind the east coast, and WA is two to three hours behind.
- Don't ignore the ACT: People joke that Canberra is boring, but the national galleries and museums are world-class and mostly free.
- Flying is often cheaper than driving: Australia is huge. Driving from Perth to Sydney takes about 40 hours of actual road time. Sometimes a $200 flight is better than $600 in petrol and three days in a car.
