Ever look at your power bill and wonder why it's so expensive?

Finder's own research shows that nearly one in four people don't have a good understanding of their power bill, so comparing it to what other people are paying might be really helpful.

We asked thousands of users questions about their power bill and created this guide so you can see how your bill measures up. If you're paying above the average, chances are you can get a better deal.

Note: These averages include bills for all household sizes and are only guidelines. The average bill may actually vary.

Average electricity bills in Australia

Here's how quarterly power bills compare across the country, state by state.

StateAverage power bill (quarterly)
South Australia$414.40
New South Wales$360.20
Victoria$338.60
Queensland$333.70
Western Australia$251.40

South Australians are paying the most for their bills, with New South Wales residents coming in a close second. Western Australians pay the least for their electricity overall.

Average electricity bill by number of children

Generally, the more people you have in your household, the more power you'll chew up. Here's how average quarterly bills change based on the number of children in the family.

Number of childrenAverage power bill (quarterly)
0$325
1$360
2$401
3$439
4$540

This reflects what we already knew – children are expensive! The gap between single-child and four-child families is $215 per quarter or $860 per year.

Not only does each child have their own devices to power, but more children usually means a larger house, with greater heating and cooling costs.

Average electricity bill by generation

Our survey also grouped quarterly power bills by generation. Here are the averages for each age group.

GenerationAverage power bill (quarterly)
Gen Z (age 18–24)$371
Gen Y (age 25–39)$348
Gen X (age 40–59)$372
Baby boomers (age 60+)$297

While bills don't vary much for people under the age of 60, people born into the baby boomer generation (now aged 60 or older) have much lower average bills. This could be due to:

  • Senior and pensioner discounts/government subsidies
  • Lower electrical appliance use
  • More likely to own a house and thus a solar system

Average gas bills in Australia

While gas tends to be cheaper than power, that doesn't mean you're always getting a good deal. Comparing your expenses to what others are paying is a great way to reality-check your bill.

In this table, we've grouped average quarterly gas bills state by state. Keep in mind that our figures include every type of household, so they're only guidelines.

StateAverage gas bill (quarterly)
Victoria$234.20
South Australia$208.30
New South Wales$193.60
Queensland$183.40
Western Australia$133.70

Based on this, Victorians pay the most for gas (while paying the least for electricity), with South Australians not too far behind. Western Australians are paying the least for their gas use.

Average gas bill by number of children

More children means a greater need for cooking and heating. Here's how quarterly gas bills change with family size.

Number of childrenAverage gas bill (quarterly)
0$191
1$224
2$241
3$265
4$310

The gap between households with no children and those with four is huge, increasing average costs by roughly $120 per quarter ($480 per year). A lot of this is likely due to the fact that larger households have bigger houses, with more space to heat.

Average gas bill by generation

In our survey, we also looked at how gas bills changed by the respondents' age, grouped into generations.

GenerationAverage gas bill (quarterly)
Gen Z (age 18–24)$223
Gen Y (age 25–39)$215
Gen X (age 40–59)$216
Baby boomers (age 60+)$172

Gas bills drop a little as people age, probably due to senior/pensioner discounts and rebates or smaller household sizes after kids have left.

What goes into your gas bill?

Your gas bill is made up of two main things:

  • Overall usage. More gas means more money. While it's not too easy to reduce usage for things like cooking or hot water, check out our guide on winter heating costs.
  • Gas rates. A cheaper plan will save you money on the same overall use. It's a good idea to compare different plans if your bills are on the higher side.

What goes into your energy bill?

Your electricity bill is made up of two main costs:

How else can I reality-check my bill?

Your energy provider should include a comparison of your usage to other households in your neighbourhood. Usually, this ranks you against the average of variously sized households and is a graph somewhere on your bill.
