When you ride a bicycle, motorised foot scooter or a personal mobility device a segway, you must wear an Australian Standard (AS) approved bicycle helmet. You must securely fit and fasten it. An approved bicycle helmet means a helmet that complies with AS 2063 or AS/NZS 2063.

You may only carry passengers on your bicycle if the bicycle is designed to carry passengers. If you carry a passenger on your bicycle, they must also wear an approved helmet, securely fitted and fastened. However, if they are a paying passenger on a 3 or 4 wheeled bicycle, they do not have to wear a helmet.

You do not need to wear a helmet if you have a doctor's certificate stating that, for a specific amount of time, you cannot wear a helmet:

• for medical reasons
• because of a physical characteris that makes it unreasonable for you to wear one.

If you have a doctor's certificate, you must carry it with you when you ride without a helmet.

You also do not need to wear a helmet if you are a member of a religious group and are wearing a headdress customarily worn by your group, that makes it impracal to wear a helmet.

Attaching a camera

There is no law that prohibits the attachment of a camera to a bicycle helmet, as long as the helmet remains compliant with the above mentioned standards, and is an approved attachment (according to the helmet manufacturer).

You may use a camera mounted on your bicycle or a body mounted camera as an alternative.

Bicycle equipment

Every time you ride, your bicycle must have:

• at least 1 working brake
• a working bell, horn or a similar warning device.

Bicycle equipment for night time and unsafe weather

If you ride at night or in weather conditions that make it difficult to see, you must display (either on the bicycle or on you):

• a white light (flashing or steady) that can be clearly seen at least 200m from the front of the bicycle
• a red light (flashing or steady) that can be clearly seen at least 200m from the back of the bicycle
• a red reflector that can be clearly seen at least 50m from behind the bicycle—when a vehicle's headlights shine on it.
