LPG vs. Natural Gas: Understanding the Differences & What is Available To You As A Noosa, Gympie, or Sunshine Coast Resident

In today’s energy-conscious world, the use of cleaner and more efficient fuels has become increasingly important. Liquefied Petroleum Gas (LPG) and natural gas are two popular choices that offer numerous benefits over traditional fossil fuels. In this blog, we will explore the key differences between LPG and natural gas, shedding light on their composition, sources, properties, and applications. By understanding these distinctions, you can make informed decisions about which fuel best suits your needs and contributes to a sustainable future.

Composition and Sources

LPG, also known as propane (more commonly in America, not Australia), is a hydrocarbon gas consisting of propane and butane. It is derived from natural gas processing and petroleum refining. LPG is created through the separation of natural gas liquids (NGLs) such as ethane, propane, butane, and pentane. On the other hand, natural gas primarily comprises methane and is obtained directly from underground reservoirs or as a byproduct of oil extraction.

Energy Content and Combustion

When it comes to energy content, LPG has a higher calorific value than natural gas. This means that a given volume or weight of LPG contains more energy, making it more efficient for heating purposes. LPG releases more heat during combustion, resulting in better fuel efficiency and reduced carbon emissions compared to natural gas.

Storage and Transportation

LPG is stored and transported in a compressed or liquefied state, typically in steel cylinders or bulk storage tanks. Due to its high energy density, LPG can be easily stored and transported over long distances, making it suitable for off-grid areas. Conversely, natural gas is transported through pipelines, requiring an extensive network of infrastructure for distribution.

Interestingly, a user may only opt for natural gas where there is an available metered street connection (muck like the NBN, or electricity). The metered natural gas networks are not available to all Queensland homes. If you are living in a Noosa, Sunshine Coast or Gympie region, the only gas option available to you is LPG – the natural gas lines don’t travel up past North Brisbane.

We are commonly asked about the differences between LPG/propane appliances & natural gas appliances. If you own a natural gas heater for example, yes it is certainly possible to convert this to LPG.


LPG finds widespread use in residential, commercial, and industrial sectors. It is commonly employed for cooking, heating, and water heating in homes, as well as for powering vehicles, camping equipment, and forklifts. Natural gas, on the other hand, is primarily used for heating buildings, generating electricity, and as a fuel for industrial processes. It also serves as a feedstock for the production of various chemicals and fertilizers.

Safety Considerations

Both LPG and natural gas are flammable and require careful handling by a licensed gas fitter or energy supply company. However, LPG is denser than air and tends to sink to low-lying areas in case of a leak, while natural gas is lighter and tends to dissipate into the atmosphere. Safety measures such as proper ventilation, leak detection systems, and adherence to regulations are crucial to ensure the safe use of these fuels.

LPG and natural gas are valuable energy sources that offer cleaner and more efficient alternatives to traditional fossil fuels. While LPG boasts higher energy content and versatility, natural gas provides a reliable and cost-effective solution for heating and electricity generation. Understanding the differences between these fuels enables us to make informed choices based on our specific needs, environmental considerations, and infrastructure availability. By embracing these cleaner energy options, we contribute to a sustainable and greener future for generations to come.
