Everything you need to know before picking up the keys -- licence rules, insurance, fuel policy, deposits, and the driving habits that are different here.
In most states and territories, visitors on a tourist visa can drive on a valid overseas licence for the length of a normal holiday, provided it's current and in English. If your licence isn't in English, you'll need either an International Driving Permit (IDP) issued in your home country, or a certified English translation -- carry it alongside your original licence at all times, not instead of it.
The Northern Territory limits visiting drivers to 3 months on an overseas licence -- relevant if you're combining a long touring itinerary with time in Darwin or Alice Springs. Rules do shift from time to time, so if your trip is longer than a few weeks, it's worth a quick check with the relevant state transport authority before you travel.
Most rental companies require drivers to be at least 21 years old, with a young driver surcharge typically applying under 25. Some vehicle categories (4WD, larger vans) may set the minimum age at 25. A valid credit card in the driver's name is required for the security deposit -- debit cards are often not accepted for this purpose.
When we arrange your rental, this is generally what to expect:
Rental companies place a temporary hold on your credit card as a security bond -- this is not a charge, but the funds are unavailable to you until the car is returned undamaged and the hold is released. Bond amounts vary considerably:
| Vehicle type | Typical bond range (AUD) |
|---|---|
| Small/medium car | $300 -- $750 |
| SUV / larger car | $500 -- $1,500 |
| 4WD / campervan | $3,000 -- $7,500 |
The bond release can take 5-10 business days to reflect back on your card after return, depending on your bank -- this is normal and not a sign of a problem, but worth knowing so it doesn't catch you out mid-trip.
Standard rental rates include basic Collision Damage Waiver (CDW), but this comes with an excess -- the amount you're liable for if the car is damaged, typically $2,000-$5,000 depending on the vehicle. Most companies offer an excess reduction package (sometimes called "excess waiver" or "premium cover") that lowers this liability to a few hundred dollars or zero, for a daily fee.
We recommend confirming excess reduction cover before you drive off, particularly for self-drive itineraries that include unsealed roads, the Red Centre, or Tasmania's mountain roads.
The overwhelming majority of rentals in Australia run on a "full to full" policy -- you receive the car with a full tank and are expected to return it full. Returning with less than a full tank means the company will charge you to refill it, usually at a noticeably higher rate than the bowser price, plus a service fee.
| Rule | Detail |
|---|---|
| Side of the road | Australia drives on the left. Take extra care at intersections, roundabouts, and after fuel/rest stops -- it's easy to briefly forget, especially at quiet intersections. |
| Speed limits | Default limits are typically 50 km/h in built-up areas, 100 km/h on the open road, and up to 110 km/h on motorways -- always follow posted signage, as limits vary by state and specific road. |
| Mobile phones | Hand-held phone use while driving is illegal nationwide. Hands-free (Bluetooth, mounted, voice-activated) is permitted for full-licence holders. |
| Drink driving | The legal limit is 0.05 BAC for full licence holders. The safest approach for visitors is simply not to drink at all before driving. |
| Seatbelts | Mandatory for every seat, every trip, no exceptions -- fines apply per unbelted passenger, including in the back seat. |
| School zones | Drop to 40 km/h during school zone hours (generally 8-9:30am and 2:30-4pm on school days) -- actively enforced by camera. |
| Roundabouts | Give way to vehicles already in the roundabout, approaching from your right. |
Kangaroos, wallabies, and wombats are a genuine road hazard, particularly at dawn and dusk in rural and regional areas. Our strong recommendation: avoid driving in rural areas after dark wherever your itinerary allows, and if an animal does appear on the road ahead, brake firmly in a straight line -- do not swerve. Swerving to avoid an animal causes far more serious accidents than the animal strike itself.
Sydney, Melbourne, and Brisbane all have electronic tolling with no boom gates or cash payment -- tolls are captured automatically by overhead cameras reading your number plate. Most rental companies automatically enrol your vehicle in a toll pass and either bill tolls to your card after return or charge a small daily service fee while you're using toll roads. Confirm this arrangement at pick-up so you're not caught by surprise on your statement afterwards.
If your itinerary includes outback or remote touring (Red Centre, Kimberley, remote Western Australia), be aware that fuel stops can be hundreds of kilometres apart. Always fill up when you see a station rather than waiting until you're low, carry extra drinking water, and let someone know your route and expected arrival time. Standard 2WD rental vehicles are generally not permitted on unsealed outback roads -- check your rental agreement's terms before leaving sealed roads, as damage sustained off the permitted road network is typically excluded from insurance entirely.
| Situation | Who to call |
|---|---|
| Police, fire, ambulance (life-threatening emergency) | 000 (Australia's universal emergency number) |
| Non-urgent police report (e.g. minor accident, no injuries) | 131 444 (Police Assistance Line) |
| Breakdown / mechanical issue | The 24-hour roadside assistance number printed on your rental agreement -- always call the rental company first, not a random towing service |
| Accident involving another vehicle | Exchange details, photograph both vehicles and the scene, then call your rental company and (if required by their policy) the police non-urgent line |
Save your rental company's 24-hour assistance number in your phone before you drive off, and keep a photo of your rental agreement in your phone's gallery. In an emergency, your rental company can usually organise a replacement vehicle and recovery faster than a general breakdown service can.
Self-drive works brilliantly for parts of an Australian itinerary -- Great Ocean Road, wine regions, coastal drives -- and less well for others, particularly long outback stretches where fatigue and distance between services become real factors. When you enquire, tell us which sections of your trip you'd like to self-drive; we can advise honestly on where it adds to the experience and where a private transfer or guided day tour makes more sense.
Tell us which regions you'd like to explore by car -- we'll advise on the best route, rental options, and where a guided day instead makes more sense.
