The Gold Coast has both natural gas (reticulated mains, available in most coastal, inland and growth-corridor suburbs) and LPG (bottle gas, the only option for most acreage and hinterland properties). Natural gas is consistently cheaper per energy unit, but availability varies by location.
2026 fuel cost comparison
- Natural gas: approximately $0.04-0.06 per MJ delivered to the meter
- LPG (bulk delivery, twin 45kg cycle): approximately $0.08-0.12 per MJ delivered
- LPG (single 9kg bottle, BBQ-style): approximately $0.15-0.25 per MJ
Natural gas comes in at roughly half the per-MJ cost of bulk LPG and a quarter of small-bottle LPG. Plus natural gas has no delivery charges, no bottle rental, no risk of running out between deliveries.
Annual cost comparison for typical Gold Coast household
For a typical 3-4 person Gold Coast household using gas for cooktop, hot water (gas continuous flow), and occasional BBQ, total annual gas consumption is roughly 18,000-25,000 MJ.
- Natural gas: approximately $720-1,500 per year
- LPG (bulk): approximately $1,440-3,000 per year
Difference: $720-1,500 per year in favour of natural gas.
Availability map
Natural gas is reticulated through most of the Gold Coast urban area, all coastal suburbs (Main Beach through Coolangatta), all major inland suburbs (Robina, Mudgeeraba, Carrara, Ashmore, Benowa, Bundall, Southport, Helensvale), all new-estate suburbs (Coomera, Pimpama, Pacific Pines), and most canal-front (Mermaid Waters, Clear Island Waters).
LPG is the only option for acreage and hinterland suburbs (Tallai, Bonogin, Mudgeeraba acreage areas, Mount Nathan, Springbrook, Natural Bridge, Maudsland and other hinterland), plus a few pockets of older suburbs not yet connected to natural gas.
If you are unsure whether natural gas is available at your address, the simplest check is to look for a gas meter on the front boundary of nearby houses. Natural gas connections are typically clustered on a street, if your neighbours have it, you can likely get it.
Switching from LPG to natural gas
If natural gas has been brought through your street and you are still on LPG bottles, switching over typically pays for itself in 1-3 years through reduced fuel cost.
Cost to switch (typical Gold Coast residential):
- Natural gas connection from street to property (handled by gas supplier, sometimes free under promotional terms), $0-1,500
- Plumbing work to switch appliances from LPG settings to natural gas (regulators, sometimes burner orifice changes on cooktops), $400-1,200
- Removal of old LPG bottle service, $200-500
- Compliance certification, included
- Total typical $600-3,200
Annual savings $400-1,000+ depending on usage. Payback 1-4 years.
What about staying on LPG?
If natural gas is not available at your address (acreage and hinterland), LPG is your only gas option. The choices then are, stay with LPG for cooking, hot water and heating, or switch some or all of those appliances to electric.
For hot water specifically, switching from LPG continuous flow to electric heat pump usually makes economic sense even before considering convenience, federal STC rebate plus lower running cost on grid electricity beats LPG continuous flow over the unit's life. We model this at quote stage for acreage clients regularly.
For cooktop, the gas vs induction choice is more about preference than economics. Many serious cooks prefer gas. Induction is faster and more efficient. Both work fine.
For BBQ, LPG is essentially universal (almost no one runs a natural gas BBQ outdoor connection). Even natural-gas-supplied properties usually have a separate LPG BBQ bottle.
LPG bottle service for acreage homes
Standard acreage LPG service is twin 45kg bottles with auto-changeover regulator. Bottles are swapped by the gas supplier (Origin, Elgas, Kleenheat) on a delivery contract, typical cycle is 1-2 months for an average household.
Bulk LPG tanks (large in-ground or above-ground tank, refilled rather than swapped) are an option for very high consumption households or properties with multiple high-output appliances. Cheaper per MJ than bottles but higher install cost. Worth considering if monthly bottle consumption is over 100 kg.
Switching from gas to all-electric
Some Gold Coast households are switching from gas entirely to all-electric (heat pump hot water, induction cooktop, electric BBQ or no BBQ). This eliminates the gas connection cost and any gas-related risk. With solar PV, daily energy cost can be very low. We can quote the gas-removal side of a transition, capping gas lines, decommissioning bottle services, providing compliance certification.
Bottom line
If natural gas is available at your address and you are on LPG, switch over. Payback is usually 1-3 years and you stop dealing with bottle deliveries. If natural gas is not available, stay on LPG for cooking and BBQ, but consider switching hot water from LPG to electric heat pump.
Which Gold Coast suburbs actually have natural gas at the kerb
The reticulated natural gas network on the Gold Coast is run by Allgas Energy (now part of Australian Gas Networks) and coverage varies more than people realise. As a working rule for 2026:
- Full coverage: Southport, Surfers Paradise, Broadbeach, Mermaid Beach, Burleigh Heads, Palm Beach, Currumbin, Coolangatta, Bundall, Benowa, Ashmore, Carrara, Robina, Varsity Lakes, Helensvale, Pacific Pines, Coomera, Pimpama.
- Partial coverage (street by street): Nerang, Mudgeeraba village, Worongary, Ormeau, Oxenford. Older streets often have it, newer subdivisions sometimes do not.
- No coverage (LPG only): Tallai, Bonogin, Mount Nathan, Maudsland, Springbrook, Natural Bridge, Lower Beechmont, Numinbah Valley, most acreage south of Mudgeeraba.
- Apartment buildings: mostly natural gas in towers built post-1990, mixed in older walk-ups. Some Surfers towers run a centralised gas plant rather than individual meters.
The fastest check is to look at the kerb in front of your house for a yellow plastic valve cover and gas marker peg. If you see one within 20m of your boundary, natural gas is almost certainly available. The Australian Gas Networks website also offers a postcode-based connection check that gives a yes or no answer for any specific address.
What the network connection actually involves
If gas is at the kerb but not yet to your meter box, you contact Australian Gas Networks (the distributor) to apply for the connection. They run the service from the main to the meter box, typically $0-1,800 depending on whether you fall under a promotional connection deal. From the meter to the appliances is our scope (the gas fitter side).
Connection lead time is typically 3-6 weeks from application. Plan the timing if you are upgrading appliances at the same time. We coordinate with the distributor so the gas-side work happens after the meter is set. Sequence is, you apply for connection, distributor sets meter, we install appliance-side work, we test and commission, we issue compliance certificate, distributor activates gas supply.
The hidden cost of LPG nobody quotes upfront
LPG suppliers (Origin, Elgas, Kleenheat, Supagas) quote you the per-kg price but the real per-MJ cost includes several add-ons most homeowners miss until the first annual statement:
- Bottle rental: typically $80-180 per year per bottle. Twin 45kg setup is $160-360 per year before you have used any gas.
- Delivery fee: $20-45 per delivery depending on supplier and your location. Acreage further out (Springbrook, Natural Bridge) pays more.
- Minimum top-up charge: some suppliers charge a minimum even on partial deliveries.
- Out-of-cycle delivery surcharge: if you run out and need an unscheduled refill, $40-90 surcharge.
- Annual safety inspection on regulator and bottle cage: $80-150 if you want it done properly.
Add it up and the headline price per kg is closer to 30-40% higher in true per-MJ delivered cost. We tell acreage clients this upfront so they can plan whether to stay on LPG or shift the big consumers (hot water especially) to electric heat pump.
The natural-gas-meets-LPG hybrid setup
A pattern we see in newer Coomera and Pimpama estates is natural gas reticulated to the meter but the outdoor BBQ still running on a 9kg LPG bottle. The reason is simple, BBQ manufacturers ship for LPG by default, the conversion to natural gas requires a different orifice and regulator. We can convert most BBQs for $180-320 if you want one connected outdoor gas point for both BBQ and patio heater, removing the bottle entirely. Worth doing if you BBQ more than once a fortnight, payback is 2-3 years on the orifice swap plus the loss of bottle hassle.
The reverse pattern is also common in older Burleigh, Palm Beach and Surfers homes where natural gas was installed for cooktop and HWU only, but a 45kg LPG bottle was retained for pool heating or outdoor fire pit because the gas line was undersized to feed the larger appliances. Upgrading the natural gas line to feed everything is usually cheaper over a 5-year horizon than maintaining the LPG bottle service, plus the running cost savings.
Gas decommissioning, the all-electric path
The opposite direction is also growing. We are decommissioning gas at 1-2 Gold Coast properties a month now, owners switching to heat pump hot water and induction cooktop with rooftop solar feeding the load. The gas decommissioning scope is, cap the gas line at the meter, decommission and remove the meter (gas distributor task), remove appliance branches, issue a compliance certificate confirming the system is dead. Cost $400-900 typical. Stops the daily supply charge on the gas bill, which is $0.70-1.10 per day or $250-400 per year before any usage. For households running only a cooktop on gas, the daily charge alone often exceeds the actual gas usage cost.
The economics of going all-electric have shifted strongly in the last 3-5 years. Federal STC rebates on heat pump hot water knock $1,000-1,800 off install cost. Solar PV systems are paying back in 4-6 years. Induction cooktops are cheaper than premium gas cooktops and faster to heat. For owners replacing aged gas appliances, the all-electric path often wins on total cost of ownership over the next 10-15 years.
What changes if you have solar PV
Solar PV completely changes the LPG vs natural gas vs electric conversation. With a 6.6 kW or 10 kW PV system, midday electricity production is essentially free (any export earns 4-7c/kWh at current Gold Coast feed-in tariffs, much less than the cost of buying electricity at peak). Running a heat pump hot water system during peak solar hours costs essentially nothing.
For LPG households on acreage, adding solar PV plus shifting hot water from LPG continuous flow to electric heat pump on a daytime timer cuts the LPG bottle bill by 50-70% (LPG retained only for cooking and BBQ). Many acreage owners in Tallai and Bonogin have made this switch in the last 2-3 years and the math has worked out cleanly. Payback on the combined investment is 5-8 years, then ongoing savings indefinitely.
Bottom line decision tree
Three simple questions answer the LPG vs natural gas vs all-electric question for most Gold Coast households:
- Is natural gas available at the kerb? If yes and you currently use LPG, switching pays back in 1-3 years. If no, you are on LPG or all-electric only.
- Do you have or are you planning solar PV? If yes, all-electric with heat pump hot water becomes very competitive. If no, gas (natural or LPG) still wins on running cost for hot water specifically.
- What is the age of your existing appliances? If hot water and cooktop are within 5 years of end of life, plan the energy source switch at replacement time. If they are newer, run them to end of life then switch.
