Warning Signs of a Gas Leak
Most gas leaks show themselves in one of five ways. The faster you recognise these gas leak symptoms, the better the outcome.
1. The Smell of Gas
If you notice a strong smell like rotten eggs or sulphur in your home, this is the most common sign of a gas leak. Gas itself is odourless, so the smell is added to help people detect leaks more easily. The stronger the smell, the larger the leak is likely to be. If you notice it, act first and investigate second.
2. Hissing or Whistling Noises
A hissing or whistling sound near a gas appliance or pipe is another indicator that gas is escaping from somewhere. If you hear this sound, it’s time to take action quickly.
3. Dead or Dying Plants
Gas leaks in the ground can affect plant life. If you notice plants around your gas lines suddenly dying, it could be due to a leak underground. It’s worth checking if this happens.
4. Physical Symptoms
If you or anyone in your household starts feeling dizzy, nauseous, or lightheaded, it could be due to exposure to a gas leak. Symptoms like shortness of breath or irritated eyes can also be signs of a gas leak.
5. Increase in Gas Bills
A sudden spike in your gas bill with no change in your usage could point to a gas leak somewhere in your system. If you notice this, it’s a good idea to investigate further.
Think you have a gas leak right now?
1. Turn off the gas supply at the meter if it is safe to reach
2. Get everyone, including pets, out of the house
Our licensed gas fitters are on call 24 hours a day around Newcastle and the surrounding suburbs.
What to Do Immediately
If any of the gas leak warning signs are familiar to you, move through these 5 steps in order. Speed matters, but your safety comes first.
1. Turn Off the Gas Supply
Head to your gas meter and turn the supply off at the isolation valve, but only if it is safe to reach. Shutting off the flow of gas at the source reduces the risk of a larger leak or ignition.
2. Evacuate the Area
Move everyone out of the house straight away, including pets. Use an exit that is not close to where you suspect the leak, and do not stop to collect belongings. Fresh air matters.
3. Avoid Using Anything Electrical
Do not turn lights, switches, fans or appliances on or off. Leave your mobile phone alone until you are outside. A small spark can ignite escaping gas, and even a doorbell counts. Once you are clear of the property, your phone is safe to use.
4. Call for Help
From a safe distance outside, call Leak Hunters on 02 4006 8330. Our licensed Newcastle gas fitters will dispatch an emergency plumber to assess the leak, shut down the supply at the source if needed, and get your home safe again. If the leak is severe or a fire risk is present, call 000 first.
5. Don’t Go Back Inside
Stay outside until a licensed professional or the emergency services give you the all-clear. Even a small leak can build up to a dangerous concentration, and returning too soon puts everyone at risk.
How to Prevent Gas Leaks in Your Home
While gas leaks can’t always be avoided, there are things you can do to lower the risk:
Regular Inspections
Schedule a yearly inspection of your gas appliances, pipework and connections with a licensed gas fitter. Regular servicing catches small issues like worn seals, loose fittings and pilot light faults before they become leaks.
Keep Appliances Maintained
Clean gas cooktops, ovens, heaters and hot water units to the manufacturer’s recommendations. Keep vents clear, look out for yellow or orange flames where blue should be, and replace aging appliances before they fail.
Install a Gas Leak Detector
A plug-in or battery-powered gas leak detector gives you an early warning the moment concentrations climb, including at night when nobody would smell a thing. Pair it with a carbon monoxide alarm if you have any combustion appliances indoors.
Know What to Do in an Emergency
Walk every adult in the house through the five emergency steps above, and show them where the gas isolation valve is. Quick action saves property and lives.
Don’t Wait, Fix It Before It Gets Worse
Gas leaks are serious, but recognising the warning signs and knowing what to do immediately can help protect your home and family. Stay vigilant and take action as soon as you notice any signs of a gas leak to keep everyone safe. If you’re concerned about a gas leak, don’t hesitate to reach out.

Frequently Asked Questions
What does a gas leak smell like?
Most natural gas leaks will smell like rotten eggs or sulphur. Gas is odourless in its natural state, so Australian suppliers add a compound called mercaptan that gives it a strong, unmistakable smell. If the rotten egg smell is faint, you may have a small leak. A strong smell usually means a larger leak and should be treated as an emergency.
What are the first signs of a gas leak in a house?
The first signs are usually the smell of rotten eggs, a faint hissing or whistling near an appliance, plants dying near a gas line, or people in the house feeling dizzy, nauseous, or light-headed for no other reason. A sudden spike in your gas bill is another sign worth investigating, even though it tends to show up later.
Can a gas leak make you sick?
Yes. Natural gas itself is not toxic, but the mercaptan additive and the way gas displaces oxygen in a room can cause headaches, nausea, dizziness, fatigue and breathing trouble. Symptoms usually ease once you step outside into fresh air. If multiple people in the house are affected at the same time, treat it as a gas leak emergency and leave.
What should I do if I smell gas in my house?
Turn the gas off at the meter if it is safe to reach, get everyone outside, do not touch electrical switches or your phone, and call Leak Hunters on 02 4006 8330 from outside. Do not go back in until a licensed gas fitter or the emergency services tell you it is safe.
