Australia is, depending on how you measure it, either the sixth-largest country on Earth or a continent with a coastline. Most international visitors arrive expecting to drive from Sydney to Melbourne in an afternoon, look at a map, and reckon a road trip across to Perth sounds breezy. Five hours later they've recalculated, sat down with a cold drink, and accepted that they need either a much longer holiday or a flight.
This guide is the actual driving primer non-Australians need: left-hand-side basics, the real time and distance scale of the country, what to do when you encounter a road train, the wildlife situation, fuel station logistics, and the small etiquette things that mark you as someone who's done this before.
The left side: easier than you think, harder than you expect
Australia drives on the left. The steering wheel is on the right side of the car. If you've never done this before, three honest truths:
One: in city driving and on highways with traffic, your brain catches up within an hour. The cars around you are doing the right thing and you follow their lead. It's not a problem.
Two: the danger is empty rural roads at the start of your day. With no other cars to mirror, your brain reverts to your home country's defaults — especially when you're tired, in a roundabout, or making a turn from a stop. Most rental-car wrong-side incidents happen in the first 48 hours, in remote areas, on quiet roads. Stay alert specifically when conditions feel low-stakes.
Three: roundabouts go clockwise here. If your home country drives on the right, your instinct will be to enter a roundabout to the right. This is wrong and dangerous. Give way to the right (vehicles already in the roundabout) and enter to the left. Take five minutes to practice on a quiet one before you need to do it in traffic.
The distances are real
Some honest numbers, because Google Maps doesn't really prepare you:
- Sydney to Melbourne: 880 km. About 9-10 hours driving. People do it in a day but it's a full day.
- Sydney to Brisbane: 920 km. 10-11 hours. Same deal.
- Melbourne to Adelaide: 730 km. 8 hours.
- Adelaide to Perth: 2,700 km. Three full days, minimum. Most of it across the Nullarbor with very limited services.
- Darwin to Alice Springs: 1,500 km. Two days driving.
- Cairns to Brisbane: 1,700 km. Two days.
The interstate drives between capital cities are doable in a few days each. The cross-country drives (Adelaide to Perth, Darwin to Alice) are multi-day expeditions that require planning. Don't underestimate them. The combination of fatigue, monotony, and remote terrain is what makes Australian long drives genuinely dangerous — not the technical driving itself.
The safe rule of thumb: if Google Maps says a drive will take 6+ hours, assume you'll need a full day with stops, and don't plan to do anything meaningful at the destination that evening.
The wildlife problem (and it is a problem)
Kangaroos, wallabies, wombats, emus, and cattle on unfenced roads are not theoretical hazards. They're the leading cause of serious rental-car incidents in regional Australia. A full-sized red kangaroo hit at 100 km/h can total a car and seriously injure people inside it. Wombats are like driving into a stationary boulder.
The risks are highest:
- Dawn and dusk. Most native wildlife is crepuscular — active in low light. The two-hour windows around sunrise and sunset are when collisions peak.
- After rain in arid regions. Animals come to roads to drink from puddles in the run-off. Roads become unintentional watering holes.
- On rural sealed roads between towns. Highways with hard shoulders are statistically safest because animals see and avoid them. The danger zone is the two-lane country road between Town A and Town B, where shoulders are narrow and bush comes right up to the asphalt.
What to actually do:
- Avoid driving between dusk and dawn in regional areas if at all possible. This is the single most effective wildlife-collision avoidance strategy. It's also why locals plan their long drives to start at 6am and finish before 5pm.
- If you must drive at night, slow down. The faster you're going, the less time you have to react and the worse the impact.
- If an animal appears in your headlights, do not swerve to avoid it. The official, counter-intuitive advice from Australian road authorities is to brake straight, keep your wheels in your lane, and accept the impact. Swerving causes more serious crashes than the animal collision itself — either rolling the car or hitting a tree or oncoming traffic.
- Check your insurance covers wildlife strikes. Some basic rental cover excludes "single-vehicle incidents involving animals." Read the policy.
Road trains: yes, they're as long as you've heard
A road train is a single prime mover towing two, three, or sometimes four full-length trailers. Total length: up to 53.5 metres — longer than the cricket pitch you'll never go to. They operate on highways across the Northern Territory, Western Australia, South Australia, and parts of Queensland.
Things to know:
- Overtaking takes longer than your instincts tell you. A road train at highway speed needs about a kilometre of clear road for a safe overtake. Don't start unless you can see all the way past the back trailer to clear road ahead.
- The trailers swing. The rear trailer doesn't track the prime mover's line exactly — it cuts inside on curves. Give them extra space on bends.
- They can't slow down quickly. A loaded road train at 100 km/h needs hundreds of metres to brake. If you pull in too quickly after overtaking, you might force a brake action they can't safely make.
- Pull off the road when they're behind you on a single-lane road. If a road train is travelling faster than you and there's no overtaking lane in sight, slow down and pull onto the shoulder when it's safe. The driver will appreciate it, will probably flash their hazards at you in thanks, and you've earned a small bit of road respect that you won't get any other way.
The petrol-station gap problem
In urban and coastal Australia, petrol stations ("servos") are common. In the outback, they're not. The distance between fuel stops on remote highways can be 200, 300, sometimes 500+ kilometres. Running out of fuel between them isn't a minor inconvenience; depending on where you are, it can be a serious situation.
The practical rule for regional driving: refuel when you're at half a tank, not when you're nearly empty. The next servo may be closed, out of fuel, or further than your remaining range. Treat half-tank as your "find fuel soon" signal, not quarter-tank.
Some specific routes where this really matters:
- The Nullarbor (Eyre Highway, between SA and WA)
- The Stuart Highway (NT/SA)
- The Great Northern Highway (WA)
- Tanami Track and similar outback routes (specialised, plan very carefully)
On these routes, fuel-up at every roadhouse, regardless of how much you have left. The roadhouse menus are usually mediocre and the prices are higher — that's the cost of supplying fuel 400km from anywhere. Pay it without complaint.
Speed limits, signage, and the unexpected variations
Default speed limits:
- Built-up areas: 50 km/h unless otherwise signed (40 in some school and shopping zones)
- Rural roads: 100 km/h unless otherwise signed
- Highways and freeways: 100 or 110 km/h. The Stuart Highway in the Northern Territory has some 130 km/h sections — the highest legal limit in the country.
Police speed enforcement is taken very seriously and the tolerances are tight. Many states use unmarked cars and high-density camera networks. The traffic-fine system also includes demerit points that, if accumulated, can lead to licence suspension — foreigners are not exempt. Drive at the limit, not over it.
Country driving etiquette: the small things that matter
- The country wave. On quiet country roads, drivers often lift one or two fingers off the steering wheel to acknowledge oncoming cars. You don't have to do it. But returning it costs nothing and makes you feel like part of the road for thirty seconds.
- Pull over for faster traffic if there's no overtaking lane. Australian country drivers are patient with tourists, but they appreciate the small courtesy of being let past.
- Hazard lights as a thank-you. After someone lets you overtake or merge, a quick flash of your hazards is the universal "thanks" signal between drivers. Use it.
- Don't honk in the country. Horns in rural Australia are reserved for actual hazards. Honking in frustration marks you as urban or foreign.
Where to get a car
Major international rental brands (Hertz, Avis, Budget, Europcar) operate in every capital city airport. Booking ahead is usually cheaper than walking up, especially during school holidays and peak tourism months (December-January, June-July). If you're doing a long one-way drive (say, Sydney to Cairns), expect a one-way fee that can be significant; budget for it.
Compare across providers before you commit — the price spread for the same car class can be substantial between agencies in the same airport. A quick search through a comparison platform usually beats whatever you find by walking up to a counter.

One last unsolicited opinion
The road trip is the way to see Australia. Not because it's the most efficient — flying between capitals is faster — but because the country is mostly in the spaces between the cities. The roadhouses, the small towns, the long quiet stretches where you don't pass another car for an hour. That's the actual Australia people come for and then somehow miss. Plan a trip with at least one multi-day drive in it. You'll be tired and slightly bored at points. You'll also see the country.
