Every rider has done the maths at a red light. Thirty cars deep, forty degrees, clutch hand cramping, and a metre of clear tarmac running down the white line. Filtering is one of the genuine advantages of riding a motorcycle in this country. It is also one of the fastest ways to collect a fine and demerit points if you do not know your own state's rules.
Here is the short version, state by state, plus how to do it without ending up in a panel.
Filtering versus splitting: they are not the same thing
This distinction matters, because one is legal and the other almost never is.
-
Lane filtering is moving between stationary or slow-moving vehicles at low speed, usually approaching or sitting at an intersection.
-
Lane splitting is riding between lanes of traffic that is moving at speed, often on a freeway.
Every Australian jurisdiction that permits filtering permits it at low speed only. None of them permit splitting through fast-moving traffic. If the cars are doing 60 and you are threading between them, you are not filtering.
The rules that apply almost everywhere
Across the states that allow it, four conditions turn up again and again:
-
You must hold a full, unrestricted licence. Learners and provisional riders are excluded in every state that permits filtering. This is the single most commonly broken rule.
-
There is a hard speed cap, typically 30km/h. Above that speed you are no longer filtering in the eyes of the law.
- No filtering in school zones during operating hours.
-
No filtering between a vehicle and the kerb, a parked car, or the edge of the road. Passing on the left of traffic is treated differently to filtering between lanes, and is generally prohibited.
Some states add further restrictions around heavy vehicles, bicycle lanes, and roundabouts. Check your own.
State-by-state snapshot
New South Wales. Filtering is permitted for fully licensed riders at up to 30km/h. Not permitted in school zones during operating hours, alongside kerbs or parked vehicles, or past heavy vehicles such as buses and trucks.
Victoria. Permitted for fully licensed riders at up to 30km/h, between lanes of stationary or slow-moving traffic. Not permitted between a vehicle and the kerb, in bicycle lanes, or in school zones during operating hours.
Queensland. Permitted for fully licensed riders at up to 30km/h. Queensland also permits riders to travel on the shoulder or emergency stopping lane in some circumstances at up to 30km/h, which is unusual nationally and worth reading carefully.
South Australia. Permitted for fully licensed riders at up to 30km/h between lanes, with restrictions around kerbs, school zones and heavy vehicles.
Western Australia. Rules have changed in recent years. Confirm the current position on the Department of Transport site before you rely on it.
Tasmania and the Northern Territory. Both have their own positions that differ from the mainland east coast. Check the local authority rather than assuming NSW rules travel with you.
Australian Capital Territory. Broadly aligned with the NSW approach for fully licensed riders.
Because the rules diverge, the practical advice for anyone riding interstate is simple: assume the strictest interpretation until you have checked.
How to filter without getting hurt
Legal and safe are different questions. A filtering crash is usually low-speed, but low speed still means going down on your hip, knee and hands on hot bitumen next to a wheel.
Read the wheels, not the mirrors. Front wheels turning is your first and best warning that a driver is about to move into your gap. Mirrors tell you where a driver's head is. Wheels tell you what the car is about to do.
Assume no one has seen you. Filtering puts you in the exact blind spot most drivers never check. Move as though every gap could close.
Watch for door and phone movement. In stationary traffic, drivers open doors, throw cigarettes and reach for phones. Any of those things can put an obstacle in your lane in half a second.
Cover the brake and stay in first. Keep the bike in a gear that lets you accelerate out of trouble, not stall into it.
Do not filter into a gap you cannot exit. Get to the front of the queue and take a lane properly. Being stuck mid-pack when the lights change is the worst position on the road.
Pull mirrors in on a wide bike. Adventure bikes and cruisers with bar-end mirrors need more clearance than you think. Clipping a mirror at 20km/h is enough to unsettle you into the next lane.
The gear question
Filtering is the definition of a low-speed, high-contact-risk environment. You are close to hard objects, moving at a speed where an off means sliding, not flying. That is exactly the scenario abrasion resistance and hip and knee armour are designed for.
It is also the scenario where riders most commonly wear nothing protective, because the ride is short, urban and slow. The commute is where most riders crash. Kitting up for it is not overkill.

The bottom line
Filtering is one of the real perks of two wheels in Australia, and the law recognises it in most of the country. Know your state's rules, hold the right licence, keep it under 30, stay out of school zones, and read front wheels rather than mirrors.
Then dress for the tarmac, not the trip.
