Yes — all gas work in Australia must be performed by a licensed gasfitter. This includes connecting appliances, installing gas lines, servicing heaters, and any work on gas meters or regulators. DIY gas work is illegal in all states, extremely dangerous, and will void home insurance if a gas incident occurs.

Signs include a sulphur or rotten egg smell (from added odorant), hissing sounds near gas lines or appliances, dead vegetation in an otherwise healthy garden (may indicate underground leak), and physical symptoms like dizziness or nausea. If you suspect a leak: leave the building, don't use lights or electrical switches, call your gas provider from outside.

A Certificate of Compliance for Gas (or similar document depending on state) is issued by the licensed gasfitter after completing any gas installation or repair. It confirms the work was done to code and is essential for insurance purposes. Always request this certificate — a reputable gasfitter provides it automatically.

Connecting a freestanding BBQ to a permanent bayonet point with a flexible hose is generally legal as a DIY task. However, installing the bayonet point itself, running gas lines, or connecting a built-in cooktop all require a licensed gasfitter. When in doubt, use a professional — gas incidents can be fatal.
