Australian Road Rules for Motorcyclists

Lane filtering versus lane splitting

These are two different things, and only one of them is legal. Lane filtering is riding between two lanes of stationary or slow-moving traffic travelling in the same direction, at low speed. Lane splitting is doing the same thing faster, and the jurisdictions that have legislated a filtering speed limit have made splitting a separate offence. Transport for NSW puts the boundary at 30 km/h: filtering is permitted below that speed, and riding between traffic above it falls under a lane splitting offence with demerit points attached. The Northern Territory lists lane splitting and edge filtering — moving to the kerb or shoulder to pass traffic — as things a rider must not do.

In Victoria the same boundary applies. When lane filtering was introduced in 2015, the government confirmed riders could filter where it was safe at no more than 30 km/h, and stated that lane splitting — weaving between traffic at speeds greater than 30 km/h — would remain illegal. Western Australia's Road Safety Commission describes filtering as a manoeuvre at no more than 30 km/h and notes that riding between lanes faster than that is illegal. If you remember one number from this article, make it 30.

The conditions sitting on top of the speed limit matter as much as the limit itself. Filtering is only for fully licensed riders in every jurisdiction that permits it, never for learners or provisional holders, and it is routinely banned in school zones, between traffic and the kerb, and next to parked cars.

Where filtering is allowed, state by state

Filtering is legal in every state and territory, but the exceptions are not uniform, and two of them are genuinely surprising. The ACT bans filtering in any 40 km/h zone and past heavy vehicles and buses. Queensland goes the other way and allows something most riders do not know about: on roads with a speed limit of 90 km/h or more, a fully licensed rider may use the road shoulder past stationary or slow traffic at 30 km/h or less, provided it is sealed, there are no roadworks, it is not a tunnel, and it is safe. The rest of the state-by-state variance is covered in rides out of Brisbane, where the Queensland shoulder rule comes up first.

Helmets and the fines attached

Helmet law is the least negotiable rule on this list, and it is enforced with specific penalties rather than general ones. The Northern Territory publishes a table of motorcycle offences: not wearing a helmet attracts $100, a helmet that is not securely fastened $80, carrying a pillion or sidecar passenger without a helmet $80, and wearing a deteriorated or unapproved helmet $60. The NT requires an approved helmet meeting Australian standards for riders and passengers on roads and public places.

Approval standards are consistent across the country in substance. Transport for NSW requires helmets on NSW roads to comply with AS/NZS 1698 or UN ECE Regulation No 22, and to be labelled accordingly. Queensland lists the Australian standard plus ECE 22.05 or 22.06, and adds that where a helmet is Australian-standard approved, the visor or goggles must be approved to AS 1609.

• An approved helmet is required in every state and territory, for riders and passengers
• The chinstrap has to be fastened, not just present
• Pillion passengers need their own approved helmet
• A damaged or degraded helmet can be an offence in its own right
• If you are buying overseas, check the labelling standard before you rely on it

Licences when you cross a border

Australian licences are recognised across borders, but recognition comes with a time limit that tourists and long-trippers regularly pass without noticing. Transport for NSW states that interstate and New Zealand licence holders can drive or ride in NSW on their existing licence for up to three months, provided the licence is current, they are not disqualified or suspended, they carry the licence, and they can show genuine visitor status if asked. Stay longer than three months and a NSW licence is required to keep riding on NSW roads.

Visitors from overseas get a similar window, and the vehicle classes they can ride are the ones covered by their own licence class rather than a separate visitor entitlement. The practical consequence for a long lap of the country is simple to plan for and easy to forget: if you are in one state for more than a few months, check that state's conversion requirements rather than assuming your home licence still covers you.

Tolls and how motorcycles are charged

Motorcycles are handled as their own vehicle class on Australian toll roads, and the payment mechanics differ from a car. Linkt, which operates the tag and pass accounts used on the Sydney and Brisbane toll networks, states that motorcycles do not need tags to travel on toll roads, but that a motorcycle must be linked to a valid toll account or pass by registration plate. If it is not linked, each trip through a toll point attracts a video matching fee, which is waived if the trip is later transferred to a valid account.

That has a practical consequence for hire vehicles, borrowed bikes and interstate trips: the plate matters more than the tag. Linkt also notes that tolls depend on the vehicle's class and the toll road used, so the amount varies by route rather than being a single national figure.

If the trip is a road trip rather than a riding trip, the arithmetic changes — campervan hire in Brisbane is the same coastal highways with one toll class and no helmet, which is worth knowing if some of your group are riding and others are driving.

Registration of a visiting bike

Riding into another state on your own registration is fine; keeping the bike there is where the rules tighten. Transport for NSW states that a vehicle temporarily in NSW may keep its interstate or overseas registration provided the home registration is current and the number plates and labels required by that home state are displayed. If the vehicle is kept or garaged in NSW, it must be registered in NSW, and driving it otherwise is treated as driving an unregistered vehicle — a matter NSW Police may act on, particularly where the operator holds a NSW licence or is a NSW resident.

The detail that catches travellers is the definition of "kept". Long stays with the bike parked at one address for weeks at a time look much more like garaging than a vehicle passing through, and the penalties for an unregistered or uninsured vehicle are significant.

• Temporary visits can stay on home-state plates if that registration is current
• Number plates and labels must match the home state's requirements
• A bike garaged in another state normally has to be registered there
• Check the home state's own rules too — it may object to the bike being garaged interstate
• Keep registration documents with you for the trip

Riding in national parks

Park access is a state-by-state matter, and it often comes with a fee per vehicle rather than per person. NSW National Parks charges motor vehicle entry fees at 45 of its more than 890 parks and reserves, and states that the fee relates to motor vehicles rather than people, so each motor vehicle brought into the park — motorbikes included — is charged, while walkers and push bike riders enter free. At Kosciuszko National Park, entry is $29 per 24 hour period from the start of the June long weekend to the end of the October long weekend, and $17 through the rest of the year. If the trip is longer than a park visit, planning a motorcycle trip in Australia puts the park rules alongside permits and fuel.

Queensland's park rules are written around what the bike is doing rather than what it is. Trail bike riding is allowed only on some roads and tracks, riders must be licensed, bikes must be fully registered — conditionally registered bikes are not permitted — and normal road rules apply on roads inside parks and forests. Signs may restrict or prohibit vehicle access, so read them as the rule rather than as a suggestion.

• Expect a per-vehicle entry fee in fee-collecting parks, payable on the bike
• Check park alerts and closures before you ride in
• Stay on formed roads unless a track is specifically open to vehicles
• In Queensland, licensing and full registration are conditions of park riding

Wildlife signage and the quiet traps

Animal warning signs are not uniform across the country, and the timing behind them is the part riders need. Main Roads Western Australia reports that analysis on the Great Northern Highway found approximately 83 per cent of cattle-related crashes occur at dawn, dusk or night-time, and advises slowing down and watching surroundings carefully if even one animal is visible, because you cannot hear stock on the road. Treating a warning sign as valid for the next several kilometres, rather than for the exact spot where it stands, is the habit worth building.

The quieter traps are the ones with no sign at all: the ACT's 40 km/h filtering ban, Queensland's shoulder-riding rule that only applies above a certain speed limit, the Northern Territory's separate edge filtering offence, and the three-month point at which an interstate licence stops being enough. None of these are hard to comply with once you know they exist, which is exactly why interstate riders get caught by them.
