What Affects the Cost
Gas type: Natural gas and LPG have different fitting requirements, regulators, orifices, and pressure specifications. LPG work involves additional safety requirements around regulator placement, ventilation, and bottle storage setbacks.
Natural gas availability: Brisbane's natural gas network (operated by APA Group) covers roughly within 15km of the CBD. Beyond that, you are running LPG bottles (45kg swap or bulk tank). If natural gas mains pass your property but you are not connected, a new service connection through APA Group is a separate cost.
Scope: Connecting a cooktop to an existing gas bayonet ($150–$400) is simple. Running a new line from the meter to an outdoor kitchen 15 metres away costs considerably more.
Access and construction type: Queenslander homes with open sub-floor space (typically 1.5 metres or more clearance) make pipe routing straightforward. Slab-on-ground homes in newer suburbs require surface-mounted, in-wall, or ceiling-cavity routing, adding labour time.
Flexible connectors: Must be replaced when aged or during any gas work (~$30–$60 each plus labour). Check date stamps on existing connectors.
A straightforward cooktop connection to an existing gas bayonet point in a modern slab-on-ground home in Springfield sits toward $200. Running a new LPG line from a bulk tank to a rear outdoor kitchen in a Queenslander in Ashgrove, with sub-floor routing, regulator replacement, and multiple connection points (cooktop, BBQ, and gas heater), pushes toward $3,800. Most Brisbane jobs land around $750 for a short new pipe run or appliance connection with connector replacement.
Gas leaks require immediate action. If you smell gas, call APA Group's gas emergency line (1800 427 427) to isolate the supply before calling a gas fitter. For LPG, turn off the bottle valve if safe to do so, ventilate the area, and call your gas fitter. After-hours and emergency gas fitting work carries premium rates. For non-urgent work like connecting a new cooktop or adding a BBQ point, scheduling during business hours saves money.
Brisbane-Specific Considerations
Brisbane's gas market is split between natural gas and LPG, and your suburb determines which one applies. This split shapes the type of gas fitting work, the materials needed, and the total cost.
Inner and middle suburbs with natural gas (Paddington, Taringa, Coorparoo, Woolloongabba): These suburbs, roughly within 15km of the CBD, are connected to APA Group's natural gas network. Most gas fitting work here involves appliance connections and short pipe extensions on an existing network. Gas infrastructure in inner Brisbane is generally in good condition, with PE mains and copper internal pipework. Queenslander homes in Paddington, Red Hill, and Ashgrove offer excellent sub-floor access for pipe routing, making new gas line installations simpler and cheaper than in slab-on-ground construction.
Outer suburbs on LPG (Springfield, North Lakes, Redbank Plains, Caboolture): Beyond the natural gas network, LPG is the standard. This means either 45kg swap bottles or a bulk tank (typically 500L–2,000L) supplied by companies like Elgas or Kleenheat. LPG gas fitting quotes need to specify the gas type, as materials differ. Regulators, orifices, and test pressures are all different between natural gas and LPG. Converting an appliance from one gas type to the other requires a conversion kit ($80–$150 per appliance) and is regulated work that must be done by a licensed gas fitter.
Queenslander construction advantage: Elevated Queenslander-style homes with open sub-floor space are significantly cheaper and less disruptive for gas line installations than slab-on-ground homes. Pipe runs can be routed underneath the house without cutting into walls or floors. Some older Queenslanders in suburbs like Red Hill and Ashgrove have original LPG setups with outdated regulators that should be inspected and potentially replaced during any gas work.
The electrification question: Queensland's subtropical climate means gas heating demand is minimal. Most Brisbane gas fitting work relates to cooktops, hot water systems, and outdoor BBQ points rather than space heating. With induction cooktops and heat pump hot water now widely available, and Brisbane's high solar irradiance making rooftop PV highly effective, many homeowners are choosing all-electric over gas for new installations. Before investing in new gas infrastructure, consider whether an electric alternative might be more cost-effective long term.
Hiring a Licensed Gas Fitter in QLD
Queensland has a dual licensing requirement for gas work. Your gas fitter must hold both a QBCC contractor licence for gasfitting and a gas work authorisation through RSHQ (Resources Safety and Health Queensland). These are separate from a standard plumbing licence. Gas work licences in QLD can be restricted (servicing only) or fully endorsed by the Chief Inspector, so confirm the gas fitter holds the appropriate authorisation for your scope of work.
Worth checking:
Both the QBCC licence number and RSHQ gas work authorisation are confirmed before work begins
The quote specifies whether the work involves natural gas or LPG (materials and compliance differ)
A compliance certificate is provided on completion
For LPG work, the gas fitter confirms they hold the appropriate LPG endorsement
All flexible connectors on the property are inspected and replacement dates confirmed
