Quick Answer

Smartraveller says you need both an IDP and your Australian licence (a digital licence may not be accepted), and you must be 18. Belgium drives on the right with priority to the right at many junctions, the alcohol limit is 0.05 as at home, and a 10 km/h overspeed costs EUR 58.

Belgium is compact and easy to cross in a day, but for an Australian it asks for one big mental flip on arrival, and then drops you into some of the busiest motorway junctions in Europe. Before the driving, the paperwork: Smartraveller says that to drive you will need both an International Driving Permit and a valid Australian licence. It adds that a digital licence may not be accepted and that rental companies may ask for both documents. You must be at least 18. If you register as a resident with a local commune you must swap to a Belgian licence, but that is a longer-stay matter.

The side switch, then the junction rule

Australia drives on the left; Belgium drives on the right. The first hour is where mistakes happen: pulling out of a car park, taking a roundabout that now runs anticlockwise, or a reflex glance the wrong way at a junction. Belgian traffic is dense, and the Brussels ring (R0) is a fast, multi-lane loop with merges coming thick and fast. If you can, take your first proper drive somewhere quiet before tackling the ring.

Smartraveller flags a second trap that has nothing to do with sides. Belgium uses priority to the right: drivers must give way to vehicles approaching from the right at intersections. The advice says this is often a surprise to foreign drivers and results in accidents. On a quiet residential street with no signs, the car emerging from your right has the right of way, even if your road looks like the main one.

Speed limits against Australia

AustraliaBelgium
Towns50 km/h50 km/h (Brussels default 30)
Rural100 km/h70 in Flanders, 90 in Wallonia
Motorway110 km/h120 km/h

The rural row is the one to learn. Where you would do 100 on an Australian open road, Flemish country roads are signed at 70, and the Brussels region defaults to 30 km/h in town. Belgium is crowded with fixed and average-speed cameras.

What a mistake costs

A first-band overspeed (10 km/h over) is EUR 58, 20 over EUR 116, and 30 over EUR 179 or a court appearance. Phone use and a red light are each EUR 174, and an unbuckled belt is EUR 116. The speeding fine calculator can estimate anything heavier. Compared with the Australian scale, where a 10 over fine can start at AUD 200 and carry demerit points, the euro figures look modest, but the cameras mean you are far more likely to be caught.

Alcohol and the car

The limit is 0.05, the same as most of Australia, so there is no surprise, but enforcement is heavy. Belgium also requires more in the boot than Australia does. A warning triangle, reflective vest, first aid kit and fire extinguisher are all mandatory, and roadside checks happen. A hire car should carry them, but count them before you drive off.

Other things Smartraveller notes

  • Road conditions and road safety are very good throughout the country.
  • Strike action is an ongoing issue; it can be announced at short notice and cause severe disruption on roads and at airports.
  • Only use licensed taxis; assaults and robberies have occurred in unlicensed ones, and the Uber app is available.
  • Electric scooters are capped at 25 km/h, with no passenger allowed.

Emergency numbers

Australia’s 000 does not work here. In Belgium dial 112 for any emergency, 101 for the police or 100 for an ambulance or the fire service. There is also an official emergency services app for people who cannot call.

Read the full rules on the Belgium driving guide, and use the driving permit checker to confirm your own paperwork.

Frequently Asked Questions

Yes, but carry an International Driving Permit alongside it. Smartraveller's Belgium advice says you need both documents, that a digital licence may not be accepted, and that car rental companies may require both. You must be at least 18. Arrange the IDP in Australia before you fly.

Check if your licence is valid

The right. Coming from left-driving Australia, your first day is the risky one. Roundabouts flow anticlockwise and the Brussels ring road throws fast, dense multi-lane merges at you from the off.

Belgium's limit is 0.05 BAC, the same as most of Australia, but enforcement is heavy and a 10 km/h overspeed already costs EUR 58. Cameras are everywhere.

Check your blood alcohol limit

At intersections without signs or markings that say otherwise, you give way to vehicles approaching from your right. Smartraveller warns that this often surprises foreign drivers and results in accidents.
