Gas Comparison

Ever looked at your gas bill and wondered if what you're paying is normal? Understanding your gas consumption is the first step to managing your bills and finding potential savings. Gas usage can vary significantly based on where you live, the size of your household, and even the time of year. 

This guide breaks down what typical gas consumption looks like across Australia. We’ll explore how factors like your state, household size, and seasonal changes affect your usage. By the end, you'll have a clearer picture of your gas consumption and be better equipped to find a plan that fits your needs. 

Key Takeaways 

  • State Differences: Victoria has the highest average household gas consumption, while Queensland has the lowest. 
  • Seasonal Impact: Gas usage peaks in winter due to heating needs and is lowest in summer. 
  • Household Size: Larger households naturally use more gas, but the increase isn't always linear. 
  • Main Uses: Most residential gas is used for heating, hot water, and cooking. 

Average Gas Consumption in Australia 

Across Australia, gas is a major energy source, making up approximately 27% of the nation’s total energy consumption, according to the Australian Energy Update 2020–21. While much of this is for commercial and industrial purposes, millions of homes rely on the gas network every day.. 

Several key factors influence how much gas your household uses: 

  • Climate: Cooler regions like Victoria, Tasmania, and the ACT have much higher gas consumption, especially in winter, due to the demand for heating. In these areas, winter usage can account for nearly half of the annual total. In warmer climates like Queensland, winter gas use is significantly lower. 
  • Household Size: The more people living in a home, the higher the gas consumption, particularly for hot water and cooking. 
  • Lifestyle and Appliances: The number and type of gas appliances you own (e.g., heaters, hot water systems, stovetops) play a huge role in your overall usage. Homes with gas space heating use considerably more gas than those without. 

Average Gas Consumption per Household 

Understanding your household's gas consumption starts with knowing the national and state averages. The table below provides a snapshot of the average annual gas usage for households across different states.

As you can see, Victorians use nearly seven times more gas on average than Queenslanders, highlighting the massive impact of climate on energy needs. 

Average Gas Consumption (MJ) by State, Household Size, and Season 

To get a more detailed picture, let's break down gas consumption by household size and season for each state. This data helps you benchmark your own usage more accurately. 

New South Wales 

In NSW, gas usage climbs steadily during the cooler months. A typical household uses almost double the amount of gas in winter compared to autumn or spring.

How Gas is Used in Australian Households 

Most homes use gas for three main purposes: 

  • Heating: This is the largest driver of gas consumption, especially in southern states. Homes with gas space heating consume significantly more gas than those without. 
  • Hot Water: Gas hot water systems are common and contribute a steady amount to your daily gas usage. 
  • Cooking: Gas stovetops and ovens are popular for their responsiveness, but they account for a smaller portion of total gas use compared to heating and hot water. 

The sharp increase in winter bills is almost entirely due to heating. As temperatures drop, households run their gas heaters for longer, causing gas consumption to spike. 

Gas Pricing and Units Explained 

Understanding your gas bill can feel complicated, but it comes down to a few key terms. 

What is a Megajoule (MJ)? 

Gas usage is measured in megajoules (MJ). A megajoule is a unit of energy, equivalent to one million joules. Your gas meter records how many megajoules you use, and your retailer charges you based on this amount. 

Average Cost of Gas per MJ in Australia 

The price you pay per megajoule varies depending on your state, retailer, and specific plan. Gas rates are typically between 2 and 6 cents per MJ (c/MJ). Often, plans have "block rates," where the price per MJ changes after you've used a certain amount. 

How to Calculate Your Gas Usage 

The easiest way to track your gas consumption is by looking at your bill. It will show your total usage in MJ for the billing period and the corresponding charges. 

If you want to monitor your usage more closely, you can read your gas meter. Your meter will show a reading in cubic metres (m³), which your gas provider converts to megajoules using a specific formula. By taking readings at different times, you can calculate your daily or weekly usage. 

Find a Ideal Gas Plan for Your Home 

Now that you have a better understanding of average gas usage, you can see how your own consumption compares. If your bills seem high, or if you haven't reviewed your plan in a while, you could be missing out on potential savings. 

Comparing gas plans is a simple and effective way to take control of your energy costs. At ElectricityProvider.com.au, you can compare plans from a range of trusted retailers to find one that fits your household's needs and budget. The process is quick, easy, and could lead to significant savings on your next bill.
