One-way trafficAustralia
11. One-way traffic
One-way traffic means that vehicles on a road or carriageway may travel only in one designated direction. The permitted direction is normally indicated by traffic signs, lane arrows or road markings.
Some road users, such as cyclists or public-transport vehicles, may be allowed to travel in the opposite direction when signs expressly permit it. A one-way road does not by itself determine the speed limit, priority or parking rules.

How should I read a one-way restriction in Australia?
Australian one-way requirements are regulated by the relevant state or territory. In New South Wales, follow the one-way street rule and any specifically authorised lane or sign arrangement.

May cyclists travel against the general traffic direction in Australia?
The NSW Road Rules provide for bicycle riding against the general direction where the applicable bicycle-lane or sign arrangement authorises it. That state example is not permission to ride against every Australian one-way street.

Does one-way traffic give me priority or a different speed limit in Australia?
A one-way restriction concerns direction. Continue to follow the applicable speed limit, signals, give-way or stop controls and junction-priority rules. Where authorised counterflow traffic exists, check for it before turning or crossing; your permitted direction is not automatic junction priority.
