Spotting Gas Leaks Early: Key Signs Every Mackay Homeowner Should Know

Reef City Plumbing • August 18, 2025

Gas is a convenient and efficient energy source for many Gladstone homes, powering hot water systems, heating, and cooking appliances. But while gas is safe when installed and maintained correctly, a leak can pose serious risks to both health and property. Early detection is critical — not only to prevent potential explosions or fires but also to protect your family from harmful exposure.


Knowing the signs of a gas leak and acting quickly could save lives. This guide will walk you through the key warning signs, why quick action is essential, and why engaging a licensed gas fitter in Gladstone is the safest step if you suspect a problem.

Why Gas Leaks Are Dangerous



A gas leak is more than just a maintenance issue — it’s an urgent safety hazard. Two main risks come with leaking gas:


  • Fire and Explosion Risk – Natural gas and LPG are highly flammable. Even a small spark from an appliance, electrical switch, or static electricity can ignite gas in the air.
  • Health Hazards – Prolonged exposure to gas can cause headaches, dizziness, nausea, and in severe cases, unconsciousness. Some gases, such as carbon monoxide, are odourless and can be fatal without warning.


Because leaks can escalate quickly, the moment you suspect a problem, it’s important to shut off the gas supply (if safe to do so), ventilate the area, and call a licensed professional immediately.


Common Causes of Gas Leaks


Understanding how leaks happen can help you take preventative measures. In Gladstone homes, the most common causes include:


  • Faulty Appliance Connections – Poorly fitted or deteriorating hoses and seals.
  • Corroded or Damaged Pipework – Particularly in older properties or areas exposed to moisture and salt air.
  • Poor Installation Work – Gas systems installed by unqualified individuals can have dangerous flaws.
  • Wear & Tear – Regular use of gas appliances naturally leads to component wear.
  • Accidental Damage – Renovation or landscaping work that disrupts buried gas lines.


Early Warning Signs of a Gas Leak


Spotting the signs early is essential to preventing harm. Here are the most common indicators every homeowner should know.


1. Distinct Gas Odour

Natural gas and LPG are given a chemical additive (often described as smelling like rotten eggs) so leaks can be detected quickly. If you notice this distinctive smell, especially near appliances or pipework, treat it as a serious warning.


2. Hissing or Whistling Sounds

Gas escaping from a pipe or fitting can create a hissing or whistling noise. If you hear this near a gas appliance, connection, or meter, shut off the supply and call a professional immediately.


3. Dead or Discoloured Vegetation

Gas leaks underground can affect plant life. If you notice patches of dead grass or plants in an otherwise healthy garden, particularly near where your gas lines run, this could be a sign of a hidden leak.


4. Bubbles in Standing Water

If a gas line runs beneath wet ground or puddles, escaping gas can cause bubbles to form on the surface. This is a common sign of a buried pipe leak.


5. Sudden Health Symptoms

Exposure to leaking gas can cause:


  • Headaches
  • Nausea
  • Dizziness
  • Fatigue
  • Difficulty breathing


These symptoms often improve when you leave the property, which is a key clue that gas exposure may be the cause.


6. Higher-Than-Usual Gas Bills

If your gas usage hasn’t changed but your bills have suddenly increased, a leak could be wasting gas somewhere in your system.


What to Do if You Suspect a Gas Leak


If you detect any signs of a gas leak, act immediately:


  1. Turn Off the Gas Supply – Locate your gas meter or cylinder valve and shut it off.
  2. Ventilate the Area – Open windows and doors to disperse the gas.
  3. Avoid Sparks or Flames – Don’t use electrical switches, lighters, matches, or appliances.
  4. Evacuate the Property – Ensure everyone, including pets, is safely outside.
  5. Call a Licensed Gas Fitter – Contact a qualified gas fitter in Gladstone to inspect and repair the leak.
  6. Do Not Re-Enter Until Safe – Only return to the property when the gas fitter has confirmed it’s safe.


The Role of a Licensed Gas Fitter


A licensed gas fitter is trained to safely install, maintain, and repair gas systems in compliance with Australian standards. When called to investigate a leak, they will:


  • Conduct a full system inspection to locate the source of the leak.
  • Test all appliances, fittings, and pipework using specialised equipment.
  • Repair or replace faulty components with approved parts.
  • Ensure your system is safe and compliant before turning the gas back on.
  • Provide advice on ongoing maintenance to reduce the risk of future leaks.


Attempting to fix a gas leak yourself is illegal and highly dangerous. In Queensland, all gas fitting work must be carried out by a licensed professional.


Preventing Gas Leaks in Your Home


While not all leaks can be avoided, regular maintenance and safe practices can significantly reduce your risk:


  • Annual Inspections – Have your gas system and appliances checked by a licensed gas fitter.
  • Use Qualified Installers – Ensure any new appliances or lines are installed by professionals.
  • Replace Aging Components – Hoses, seals, and pipework can degrade over time.
  • Be Cautious During Renovations – Always locate and protect gas lines before building or digging.
  • Watch for Signs – Stay alert to the early warning indicators outlined above.


Gas Safety for Landlords & Property Managers


If you own or manage rental properties in Gladstone, you have a legal duty to ensure gas systems are safe and compliant. This includes:


  • Arranging regular inspections by a licensed gas fitter.
  • Providing tenants with instructions for safe gas use.
  • Responding promptly to reports of gas smells or appliance faults.
  • Keeping records of all gas fitting work and safety checks.


Regular maintenance not only keeps tenants safe but also protects the value of your investment property.
