Australian electricity bills can be confusing — full of jargon, multiple charges, and mysterious line items that make it hard to know what you're actually paying for. Understanding your bill is the first step to reducing it. This guide breaks down every section of a typical electricity bill so you can spot overcharges, compare plans effectively, and find opportunities to save.
The Two Main Charges on Every Bill
Every electricity bill in Australia has two core charges: the supply charge and the usage charge. Together, these make up the vast majority of your total bill.
Supply Charge (Daily Fee)
The supply charge — sometimes called the daily service charge or connection fee — is a fixed daily amount you pay just for being connected to the grid. It doesn't matter whether you use any electricity at all; this charge applies regardless. Typical supply charges range from $0.90 to $1.30 per day, which adds up to $82–$119 per quarter before you've used a single kilowatt-hour.
This charge covers the cost of maintaining the poles, wires, and infrastructure that deliver electricity to your home. It's set by your network distributor and passed on by your retailer.
Usage Charge (per kWh)
The usage charge is what you pay for the electricity you actually consume, measured in cents per kilowatt-hour (c/kWh). This rate varies significantly by state and retailer, typically ranging from 25c to 42c per kWh. Some plans have a single flat rate, while others use time-of-use pricing with different rates depending on when you use electricity.
Average Electricity Rates by State
| State | Avg Usage Rate (c/kWh) | Avg Supply Charge ($/day) | Avg Quarterly Bill |
|---|---|---|---|
| Queensland | 25–30c | $0.95–$1.05 | $350–$420 |
| New South Wales | 30–36c | $1.00–$1.20 | $400–$500 |
| Victoria | 27–33c | $1.05–$1.25 | $370–$440 |
| South Australia | 35–42c | $1.05–$1.25 | $470–$560 |
| Western Australia | 28–32c | $1.00–$1.10 | $380–$450 |
| Tasmania | 25–29c | $0.90–$1.00 | $350–$410 |
| ACT | 24–28c | $0.95–$1.05 | $340–$400 |
| Northern Territory | 26–29c | $0.85–$0.95 | $450–$540 |
Controlled Load Charges
If your home has an electric hot water system or pool pump on a dedicated circuit, you may see a controlled load charge on your bill. This is a cheaper tariff — typically 15–22c per kWh — applied to appliances that only run during off-peak hours (usually overnight). Controlled load circuits have their own meter and appear as a separate line item on your bill.
Not sure if you have one? Look for terms like "controlled load," "CL1," "CL2," "dedicated circuit," or "off-peak hot water" on your bill. If you have an electric storage hot water system and you're not on a controlled load tariff, switching could save you $200–$500 per year.
Solar Feed-in Credits
If you have solar panels, your bill should show solar feed-in credits — the amount you're paid for excess electricity exported to the grid. Current feed-in tariffs across Australia range from 5c to 12c per kWh, depending on your state and retailer. These credits appear as a deduction on your bill, reducing the total amount you owe.
GST and Concessions
All electricity charges in Australia include 10% GST. This is usually shown as a separate line item at the bottom of your bill. If you hold a valid concession card (Pensioner Concession Card, Health Care Card, DVA Gold Card, or equivalent), you may be eligible for an energy concession that reduces your bill. Concession discounts vary by state — in Victoria, for example, the annual electricity concession is around $250.
How to Find Your Actual Rates
Your rates are usually listed in the detailed charges section of your bill, but they can be hard to spot. Here's where to look:
- Rate summary box: Most bills have a summary showing your tariff type and rates near the top or bottom of page 2.
- Detailed charges: Look for the section that breaks down your usage in kWh multiplied by your rate in c/kWh.
- Your energy plan document: When you signed up (or last switched), your retailer should have sent you an Energy Price Fact Sheet. This is the clearest source of your actual rates.
- Retailer app or portal: Most retailers now let you view your plan details, current rates, and usage data through their app or website.
Estimated vs Actual Reads
Check whether your bill is based on an actual meter read or an estimated read. Estimated bills are marked with an "E" next to the meter reading and are based on your historical usage — they can be significantly higher or lower than your real consumption. If you have a smart meter, all reads should be actual. If you still have an old analogue meter and your bill is estimated, you can submit your own meter reading to your retailer to get an accurate bill.
What to Do Next
Now that you understand your bill, you're in a much better position to reduce it. Start by checking whether your tariff type (flat rate vs time-of-use) suits your household, compare your rates against other retailers using a government comparison site like Energy Made Easy, and make sure you're claiming any concessions you're entitled to. Even small changes — like switching to a controlled load tariff for hot water — can make a meaningful difference each quarter.
