You’ve probably looked at a world map and seen that massive chunk of land sitting on the left side of the Australian continent. Honestly, most people just glaze over it. It looks like a big, orange rectangle with a few jagged edges. But when you actually start looking at Western Australia on map, the sheer reality of its size starts to feel a bit ridiculous.
It’s huge. Like, "four times the size of Texas" huge. Or "larger than the entirety of Western Europe" huge.
If you were to drive from the bottom corner up to the top, you’re looking at a 3,000-kilometre trek. That’s basically like driving from London to Istanbul, except instead of crossing dozens of borders and hearing ten different languages, you’re mostly just seeing red dirt, road trains, and the occasional emu looking at you like you’ve lost your mind.
Where Western Australia Sits in the World
Geographically, this state is an island within an island. It occupies the entire western third of the Australian landmass. To its north and west, you have the Indian Ocean stretching out toward Africa and Southeast Asia. To the south is the Southern Ocean—next stop, Antarctica.

Then there’s the "back door." To the east, WA is bordered by the Northern Territory and South Australia. But "border" is a loose term here. It’s mostly just an imaginary line (the 129th meridian east) running through some of the most inhospitable desert on the planet.
Most of the 3 million people who live here are crammed into the southwest corner. Specifically, Perth. If you look at a population density map, the rest of the state looks practically abandoned. It’s one of the loneliest places on Earth, and that’s exactly why people love it.
The Weird Truth About the Borders
Interestingly, the land border isn't even a perfectly straight line. Because of some 1920s surveying errors, there’s a tiny strip of land where the borders don't quite meet, creating a "no man's land" called the Surveyor Generals Corner. It’s a geeky map fact, but it proves that even on paper, this place is hard to pin down.
Breaking Down the Regions (What the Map Doesn't Tell You)
When you look at Western Australia on map, it’s usually divided into nine or ten official regions. But let's be real—to a traveler or a local, it’s basically split into three distinct "vibes."
The Tropical North (The Kimberley)
This is the top bit. It’s rugged, red, and wet. During the monsoon season (December to March), the maps essentially change because half the roads disappear under water. You’ve got the Bungle Bungle Range—these weird beehive-shaped mountains—and the Horizontal Falls, which are literally waterfalls that flow sideways because the tides are so aggressive.

The Arid Heart (The Pilbara and Goldfields)
This is the engine room of Australia. If you see a map of global iron ore exports, it starts here. It’s ancient land. We’re talking 3.5-billion-year-old rocks in the Hamersley Range. It’s where you find Karijini National Park, which is basically a series of terrifyingly beautiful cracks in the earth filled with turquoise water.
The Mediterranean South (The Wheatbelt and South West)
This is the "civilized" part. It’s where the wine is. If you find Margaret River on the map, you’re looking at world-class surf and even better Cabernet. The tall Karri forests here are so dense they actually show up as a dark green smudge on satellite imagery, a stark contrast to the rusty orange of the rest of the state.
Why the Scale Matters for Your GPS
One thing that kills tourists is underestimating the map. You see two towns that look "close" together.
"Oh, it's only a few centimeters on the screen," you think.
Wrong.
In WA, "just up the road" can mean a six-hour drive. If you're planning a trip, you have to account for the fact that there are stretches of road, like the Nullarbor Plain, where you’ll travel 146.6 kilometres without a single turn. It’s the longest straight stretch of road in the world.
The Underwater Map: Ningaloo vs. Great Barrier Reef
Everyone knows the Great Barrier Reef on the east coast. But look at the western edge of the map, near Exmouth. That’s Ningaloo Reef.
The big difference?
On the east coast, you need a boat to see the reef. At Ningaloo, the reef is right there. You can literally walk off the beach into the water and be surrounded by whale sharks and manta rays. On a map, it looks like a thin white line hugging the coast, but in reality, it’s 260 kilometres of accessible coral.
Navigating the "Empty" Spaces
There’s a common misconception that the interior of Western Australia is just "nothingness." That’s a total lie.
If you look at a specialized geological map, you’ll see the Yilgarn Craton. It’s one of the most stable, ancient pieces of the Earth's crust. It’s why the state is so flat—it hasn’t had a major mountain-building event in hundreds of millions of years. It’s just been slowly wearing away, leaving behind the weird, beautiful formations like Wave Rock or the Pinnacles.
Practical Steps for Your WA Adventure
If you’re actually planning to move or travel across this massive map, here’s the reality check:
- Download Offline Maps: Do not rely on 5G. Once you leave the Perth metro area, your phone becomes a very expensive paperweight for navigation. Use apps like Hema Maps or WikiCamps.
- Watch the Fuel: On the map, look for the "Roadhouses." These aren't just gas stations; they are life-support systems. If you see one, and you’re at half a tank, you fill up. No exceptions.
- Respect the Seasons: Don't go to the Kimberley in February unless you want to be trapped by floods. Don't go to the Wheatbelt in January unless you want to melt.
- The "Sandgroper" Factor: Locals call themselves Sandgropers. It’s a nod to the fact that much of the coastal map is literally just sand. Wear a hat.
Western Australia is one of the few places left where the map still feels like a bit of a mystery. Even with satellites and Google Street View, there are corners of the Kimberley or the Great Victoria Desert that feel fundamentally untouched. It's a place that demands respect, mostly because of its sheer, humbling scale.
To get started on a real itinerary, your first move should be checking the official Main Roads WA website for current road closures. In a state this size, the map changes daily based on fires, floods, and roadworks. Map out your distances between fuel stops before you even think about packing a bag.
