Average Gas Bills by Household Income

In the table below, we look at how much households are paying for gas based on the total household income.

Household Income Average Quarterly Gas Bill
Less than $30,000 $150
$30,000 to $49,999 $196
$50,000 to $79,999 $192
$80,000 to $119,999 $214
$120,000 and over $215

Source: Canstar Blue research, November 2021.

It’s pretty evident that the more money a household makes, the higher gas expenses are likely to be. That being said, higher income households are seemingly more likely to live in larger homes, with greater energy usage requirements. These findings don’t necessarily suggest lower income families get better gas deals or pay cheaper rates per megajoules (MJ).

Average Gas Bills by Age Group

Here are the average gas bills reported across Australia by age group of the survey respondent.

Age Group Average Quarterly Gas Bill
18 to 29 years $218
30 to 39 years $225
40 to 49 years $218
50 to 59 years $189
60 to 69 years $183
70 years and over $167

For the most part, there’s a trend of gas bills decreasing the older the customer is. This may be the result of customers being eligible for certain energy rebates or concessions, or it could be down to gas consumption habits between different age groups, or simply that most Aussies aged 60 and over have already kicked the kids out.

Average Gas Usage and Supply Rates

We’ve calculated the average usage rates and supply charges for each state by looking at four of the biggest gas suppliers – AGL, EnergyAustralia, Origin and Alinta Energy. This is a general guide only and prices are indicative of each provider’s cheapest market offer.

State Average Usage Rate Average Supply Rate
Victoria 2.37c/MJ 70.58c/day
New South Wales 3.51c/MJ 62.09c/day
South Australia 4.01c/MJ 74.55c/day
Queensland 4.86c/MJ 70.65c/day

Average usage and supply rates are for residential customers on a single rate tariff. Averages based off AGL, EnergyAustralia, Origin and Alinta Energy for VIC, NSW and SA, while averages based off AGL, Origin and Alinta Energy for QLD. Postcodes used for example, 3000, 2000, 5000 and 4000. Accurate as of January 2022.

As you can see in this comparison, Victoria has the cheapest gas usage rate, while QLD has the most expensive. For average gas supply rates, we see that NSW has the lowest price, and SA has the highest.

Gas Bill Frequency

In our survey, 53% of customers said they receive gas bills every quarter, while 24% of households receive theirs bi-monthly, and 20% monthly. Some gas suppliers will have multiple billing options, while others require a specific billing cycle, which is why it’s best to check the fine print before signing up to a deal.

What impacts average gas bills?

Gas meter with coins in front

Natural gas is fairly similar to electricity in that there are many factors that contribute to your overall costs. Before choosing a gas plan, it’s important to think about which features are most important to you. Here’s what you should consider:

  • Usage charges: Some gas suppliers have set rates for all gas usage, while others charge gas usage in ‘blocks’, meaning prices will change depending on how much gas your household consumes.
  • Supply charges: Gas supply charges are the underlying costs of supplying gas to your home – via the gas mains network. Supply charges are generally the fixed price component of a gas bill.
  • Hidden fees: Some gas suppliers may tuck fees away in the fine print, such as a connection fee, credit card surcharge, late payment fee, or a paper billing charge. This is why reading every detail of a gas plan is important.
  • Customer service: Is the level of service you receive from your gas supplier really up to scratch? Whether it’s having longer call centre hours, or an easy sign-up process, customer service is worth thinking about.
  • Location: Geography plays a major part in the price of natural gas. Customers should consider the difference in supply and running costs, especially if you live in a regional area or have lower gas usage needs.
  • Incentives: Whether it’s discounts or a rewards program, incentives are a great way for providers to compete for your business. It might even be a larger discount for bundling utilities with the same provider.
