Living next to a gas line is generally not dangerous when the infrastructure is intact, maintained and undisturbed. The main risks are an active gas leak and accidental damage during digging or construction, not proximity alone.
What determines the risk?
The line’s type, condition, pressure and location, as well as nearby activity, affect the risk:
- Transmission pipeline: Moves gas over long distances, often at high pressure.
- Distribution main: Supplies the local network, commonly beneath streets.
- Service line: Connects the distribution main to a property’s meter.
- Private gas pipework: Generally runs from the meter to appliances, although the distributor should confirm the exact responsibility boundary.
There is no universal safe distance from a gas line. Requirements depend on the asset, site and proposed work. Pipeline markers indicate only a general route, not the exact location or depth. Easements may restrict digging, building or planting.
Before digging near a gas line
Obtain current underground-service information through Before You Dig Australia before any excavation, including landscaping, fencing or drainage work. Plans may show only an approximate location, so follow each asset owner’s instructions and arrange professional onsite locating where required. Read how concealed gas pipes are located safely before planning work near a suspected route.
Before disturbing soil:
- Check available property plans and easement conditions.
- Submit a Before You Dig Australia enquiry and review every response.
- Confirm whether locating, permission or operator supervision is required.
- Never expose, test, move or repair gas infrastructure yourself.
Gas work is hazardous and regulated. Network assets must be handled by their operator, while private gasfitting work in NSW requires an appropriately licensed professional.
If you suspect a leak or damaged line
Possible signs include a sulphur-like gas odour, hissing, visible pipe damage or unexplained dying vegetation near a buried route. A leak may not always produce an obvious smell. Check who to call if you smell gas in a public area so the correct network operator can respond.
- Stop work and move everyone well away.
- Avoid flames, smoking, electrical switches, vehicles and phone use near the suspected leak.
- Do not touch, cover or attempt to repair the pipe.
- From a safe location, call 000 if there is fire, injury, immediate danger or a major gas release.
- Contact the relevant gas distributor’s emergency line and stay away until emergency services or the operator says it is safe.
Once the operator or emergency services says the area is safe, contact our licensed Sydney gas leak service if the issue concerns private gas pipework rather than the network. A qualified gas fitter can test the private installation and advise on repairs.
