If you believe the situation is dangerous to life or property, call 000 immediately.
If you smell gas in your home or street:
Extinguish any naked flames or cigarettes, and switch off electrical devices if it is safe to do so.
Open doors and windows for ventilation if it is safe to do so.
If you know where your meter is and how to switch it off, switch off the gas at your meter.
Contact your local Gas Distributor. You'll find them listed on your AGL bill, or you can use the lookup tool on the Emergencies & Power Outages page to find your local distributor.
Contact a licensed gas fitter or plumber to check out the problem, or if you rent your property, contact your real estate or property manager.
