Gas Leak in Melbourne? What to Do Before the Plumber Arrives

A gas leak is one of the few household problems where speed and calm decisions genuinely matter. Natural gas is widely used in Melbourne homes for heating, cooking and hot water, and while it's safe when appliances and pipes are in good order, a leak needs to be treated seriously every time.

How to Recognise a Gas Leak

Natural gas is naturally odourless, so a smell is added to it to make leaks easier to detect. It's often described as rotten eggs or sulfur.

Signs to Look and Listen For

• A rotten egg or sulfur smell inside or around your property.
• A hissing or whistling sound near a gas pipe or appliance.
• A dead or discoloured patch of grass or plants over an underground line.
• Bubbling in standing water near gas lines outdoors.
• Pilot lights that keep going out, or a yellow or orange flame instead of blue on a gas burner.
• Physical symptoms, such as headaches, dizziness, nausea or unusual tiredness that improves when you leave the house.

If you notice any of these, treat it as a possible gas leak. It's always better to be safe than sorry.

What to Do Immediately If You Smell Gas

Step 1: Don't Create a Spark

Gas is flammable. Even a small spark can be dangerous in the wrong conditions. Avoid:

• Light switches (on or off)
• Lighters, matches and candles
• Appliances and power points
• Doorbells and garage door openers, where you can
• Using your mobile phone inside the property

Step 2: Open Doors and Windows, Only if It's Quick and Safe

Ventilating can help disperse gas, but don't delay your exit to do it. If you can open a door or window on your way out, do so.

Step 3: Turn Off the Gas at the Meter, if Safe

If you know where your gas meter is and can reach it safely, turning off the gas isolation valve can stop more gas entering the property. If you're unsure, or the smell is strong, just get out. Don't take risks.

Step 4: Evacuate Everyone, Including Pets

Get everyone out of the building and move away, ideally upwind. Don't go back in for belongings.

Step 5: Call for Help From a Safe Distance

From outside and well away from the property, call:

• Your gas distributor's emergency line. The number is on your gas bill and on your distributor's website, so it's worth saving it in your phone now.
• 000 if you believe there's immediate danger, a strong smell, or anyone is feeling unwell.

Step 6: Wait for Clearance

Don't go back inside until emergency services or the gas distributor have confirmed it's safe.

Step 7: Call a Licensed Gasfitter

Once the immediate danger has been dealt with, you'll need a licensed gasfitter to find and repair the source of the leak. A reputable plumber in Melbourne who is also a licensed gasfitter can inspect your appliances, pipework and connections, and certify the repairs.

What Not to Do

• Don't try to find the leak yourself with a flame or lighter. Ever.
• Don't turn appliances on or off to see if that helps.
• Don't ignore a faint smell. A small leak can become a big one.
• Don't attempt DIY gas repairs. Gas work is regulated and must be done by licensed professionals in Victoria. Unlicensed work is dangerous and can be illegal.
• Don't relight pilot lights repeatedly if they keep going out. There may be a ventilation or safety issue.

Carbon Monoxide: The Other Gas Danger

Gas leaks aren't the only risk. Faulty or poorly ventilated gas appliances can also produce carbon monoxide, which has no smell, colour or taste. Symptoms can include headaches, dizziness, nausea and confusion. If you suspect carbon monoxide poisoning, get into fresh air and call 000.

Warning signs of an appliance problem include:

• Soot or black staining around the appliance
• A yellow or orange flame (rather than blue)
• Pilot lights that frequently go out
• Excess condensation on windows near gas heaters

Regular servicing of gas heaters, ovens and hot water systems is the best way to reduce these risks.

After the Emergency: What Happens Next?

Once you've reported the leak and the area is safe, a licensed gasfitter will typically:

1. Inspect your appliances, pipework and connections.
2. Test for leaks using appropriate equipment.
3. Repair or replace faulty components.
4. Test the system again and confirm it's safe.
5. Provide any required compliance documentation.

Don't use gas appliances again until you've had the all-clear.
