Gas is an essential part of daily life in many Australian homes. We rely on it for heating, cooking, and hot water, but when a gas leak occurs, it can become extremely dangerous, fast. Gas leaks can put your health, your property, and even your life at risk. That’s why it’s critical to understand the warning signs and act quickly if you suspect a problem.
Why Gas Leaks Are So Dangerous
A gas leak isn’t just an inconvenience, it’s a potentially life-threatening emergency. Here’s why.
Fire and Explosion Risk
Natural gas is highly flammable. When it accumulates in an enclosed space, even a small spark from a switch, lighter or appliance can ignite it, causing devastating fires or explosions.
Gas-related house fires are not as rare as you might think, and they’re often the result of leaks that were ignored or unnoticed.
Health Hazards
Breathing in leaking gas over time can lead to serious health issues, including:
- Headaches
- Nausea
- Dizziness
- Fatigue
- Shortness of breath
Prolonged exposure can also cause loss of consciousness or, in extreme cases, death. If the leak involves carbon monoxide (a byproduct of incomplete combustion), the risks are even greater, this odourless, colourless gas is extremely toxic.
Property Damage
Even if a leak doesn’t cause an explosion, gas can still corrode fittings, damage appliances, and pose a long-term risk to the structure and safety of your home. The cost of ignoring it often far outweighs the cost of prompt repairs.
Common Signs of a Gas Leak
There are clear signs every homeowner should watch for:
- Smell of gas: The classic “rotten egg” smell is added to natural gas as a warning sign. If you notice it, act immediately.
- Hissing sounds: A faint hissing or whistling near gas lines or appliances can indicate escaping gas.
- Dead or dying plants: Gas leaks in underground lines can suffocate surrounding vegetation.
- Physical symptoms: Headaches, nausea, or dizziness that improve when you leave the house may point to a gas issue.
- Yellow or orange burner flames: Gas appliances should burn blue, yellow, or orange flames indicate improper combustion.
What To Do If You Suspect a Gas Leak
If you think there might be a gas leak in your home:
- Turn off the gas supply at the meter (if safe to do so).
- Avoid using any electrical switches, matches, or lighters.
- Ventilate the space by opening windows and doors.
- Leave the property immediately and move to a safe location.
- Call a licensed gas plumber — like the team at Collis Bros Plumbing.

In NSW (and across Australia), it’s illegal and extremely unsafe to carry out gas fitting or repairs unless you’re a licensed gasfitter. At Collis Bros Plumbing, our team is fully licensed and experienced in gas leak detection, testing, and repairs.
Preventative Gas Safety Tips
- Have your gas appliances serviced regularly (at least every two years).
- Install carbon monoxide alarms, especially near gas heaters.
- Don’t ignore odd smells, sounds, or changes in appliance performance.
- Know where your gas shut-off valve is and make sure all adults in the home do too.
