If you’re planning a new gas installation, upgrading appliances, or comparing energy options for your property, you’ve probably come across the debate of LPG vs natural gas.
While both fuel sources are commonly used in Australian homes and businesses, they differ significantly in how they’re supplied, their energy output, installation requirements, and ongoing costs.
In this guide, we’ll break down the key differences between LPG and natural gas, explain the pros and cons of each, and help you determine which option may be better suited to your needs.
Natural gas is a fossil fuel that primarily consists of methane and it’s extracted from underground reserves and delivered directly to properties through a network of underground pipelines.Since it is supplied through pipelines, natural gas is generally only available in areas where gas infrastructure already exists.
Once your property is connected to the gas network, you can access a continuous supply of gas without needing storage tanks or bottle deliveries.
Natural gas is commonly used for gas hot water systems, home heating, cooktops and ovens, gas fireplaces, and commercial kitchens
If you’re installing new gas appliances or extending existing gas lines, it’s important to have the work completed by a licensed professional.
LPG (Liquefied Petroleum Gas) is a mixture of propane and butane that is stored in pressurised cylinders or tanks. Unlike natural gas, LPG doesn’t require a pipeline connection. Instead, it is delivered directly to your property and stored onsite until needed.
This flexibility makes LPG particularly popular in regional areas, new developments, and properties where natural gas infrastructure isn’t available.
Many Melbourne homeowners also choose LPG for outdoor entertaining spaces. If you’re planning to install a gas BBQ or outdoor cooking area, our outdoor BBQ installation services can ensure everything is connected safely and correctly.
Although both fuels serve similar purposes, there are several important distinctions.
Natural gas is delivered through underground pipelines connected directly to the gas network, while LPG is stored in bottles or tanks and delivered by suppliers when required.
For homeowners who have access to natural gas infrastructure, the continuous supply can be convenient. However, LPG offers greater flexibility because it can be used virtually anywhere.
LPG contains more energy per unit than natural gas, which means it burns hotter and can often heat appliances more efficiently. As a result, LPG is frequently preferred for applications that require high heat output, such as outdoor cooking and certain heating systems.
Natural gas and LPG appliances operate at different pressures and require different burner configurations. A natural gas appliance cannot simply be connected to LPG, and vice versa, unless it has been professionally converted.
Attempting to use the wrong gas type can create serious safety risks, including gas leaks and poor combustion. Licensed technicians can inspect your setup and provide expert gas fitting services to ensure everything complies with Australian standards.
LPG systems require gas bottles or storage tanks, along with regulators and associated pipework. While both systems require professional installation, LPG often provides a practical solution where pipeline access is limited or unavailable.
Natural gas often has lower running costs per unit of energy in areas where network access already exists. However, LPG appliances can be more energy-efficient due to their higher heat output, which may offset some of the difference depending on usage patterns.
Several factors influence overall costs, including local gas prices, household consumption, appliance efficiency, delivery fees for LPG, and network connection costs for natural gas
When comparing LPG vs natural gas, the better choice often depends on your property’s location and existing infrastructure.

Ultimately, both fuel sources can provide reliable and efficient energy when installed correctly.
Natural gas offers the convenience of a continuous pipeline supply, while LPG provides flexibility and higher energy output for a wide range of applications.
However, gas systems should never be treated as a DIY project. Potential issues such as gas leaks, damaged pipework, faulty regulators, and appliance malfunctions can create significant safety hazards.
