Average energy bill Australia: costs by state & tips to save
Trying to pin down the average energy bill in Australia feels a bit like chasing a moving target. Still, if you’re looking for a ballpark figure, a typical household is currently spending around $380 per quarter.
Think of that number as a national benchmark. Your actual costs can, and likely will, swing pretty dramatically based on where you live, how many people are under your roof, and your day-to-day energy habits.
What is a Typical Electricity Bill in Australia?

While that national average is a decent starting point, it only tells part of the story. One of the biggest drivers of your final bill is simply the size of your household.
It makes sense, right? More people means more lights switched on, more devices charging, and more appliances humming away in the background. It all adds up.
To give you a clearer picture, let’s break down how those costs tend to scale. A single-person household pays an average of $263 a quarter. Add a second person, and that figure climbs to $322.
The trend continues as families grow. Three-person households average $384, four-person households pay roughly $420, and larger households of five or more are looking at bills around $453 each quarter. You can explore more data on how household size affects energy bills to see these trends in more detail.
This simple correlation highlights a fundamental truth: the more energy your household needs, the higher the cost. Getting your head around this is the first step toward figuring out where you can make changes to trim your spending.
Average Quarterly Electricity Bill by Household Size
This table shows the average cost per quarter based on the number of people living in a household.
| Household Size | Average Quarterly Bill |
|---|---|
| 1 Person | $263 |
| 2 People | $322 |
| 3 People | $384 |
| 4 People | $420 |
| 5+ People | $453 |
Seeing these numbers laid out makes it easy to compare your own bill and get a feel for whether your energy use is typical for a home of your size.
If your costs are sitting significantly higher, it’s a strong signal that there are opportunities to become more energy-efficient. In the next sections, we’ll dig into the other key factors that shape your final bill, like your location and even the time of year.
Why Your Postcode Shapes Your Power Bill
Forget the national average for a moment. The most fascinating—and often frustrating—truth about your power bill is that your postcode plays a huge role in what you pay.
Think of Australia’s power grid as a series of interconnected, but very different, local water systems. While they all deliver the same thing, the cost of building the pipes, the source of the water, and the local upkeep costs change dramatically from one town to the next.
That’s why a family in one state can pay a completely different price for power than their friends in another, even if their homes and habits are almost identical. It all comes down to a few local ingredients that create a unique cost recipe for each state and territory.
Here’s what’s driving those differences behind the scenes:
- Local Energy Sources: States still leaning on older, more expensive fossil fuels naturally have higher generation costs. On the flip side, places like Tasmania, with its wealth of low-cost hydropower, can offer much cheaper rates.
- Infrastructure and Network Costs: The poles and wires that bring electricity to your door don’t build or maintain themselves. That expense gets passed on. In states with vast distances and sparse populations, the cost per household to cover that infrastructure is simply higher.
- Government Regulations and Policies: Every state and territory government has its own rulebook. Things like subsidies, renewable energy targets, and local regulations can either push your final bill up or help bring it down.
State and Territory Cost Comparison
So, how do all those factors translate into actual dollars on your bill? The gap across Australia is pretty stark.
The table below lays out the average quarterly electricity bills, showing just how much your location matters.
Average Quarterly Electricity Bills Across Australian States and Territories
| State/Territory | Average Quarterly Bill |
|---|---|
| Australian Capital Territory | $580 |
| South Australia | $549 |
| Queensland | $502 |
| New South Wales | $450 |
| Victoria | $358 |
| Tasmania | $323 |
Note: Data reflects typical household usage and can vary.
As you can see, households in New South Wales are looking at an average of $450 per quarter, while their neighbours in Queensland face a higher bill of around $502. For a more detailed breakdown of costs in the Sunshine State, our guide on the average electricity bill in Brisbane dives deeper.
The difference is even clearer when you compare the top and bottom. The Australian Capital Territory currently has the most expensive electricity at $580 per quarter, with South Australia not far behind at $549. Meanwhile, Tasmania ($323) and Victoria ($358) enjoy the country’s most affordable power.
This state-by-state variation is why the idea of a single “average energy bill” for Australia is only a starting point. National figures are a useful benchmark, but it’s the local conditions that ultimately decide what you pay.
Decoding the Numbers on Your Energy Bill
Opening your energy bill can feel like cracking a code. But once you understand what you’re actually paying for, you can start finding real savings. The final number you see is basically a mix of two things: the power you use and the cost of just being connected to the grid.
First up is your usage charge. This is exactly what it sounds like – the cost of the electricity you’ve consumed. It’s not always a flat rate, though. Many plans now use time-of-use tariffs, which split the day into different pricing periods to help manage the strain on the grid.
Then there’s the daily supply charge. Think of this like a fixed subscription fee you pay every single day, just to have access to the electricity network. It doesn’t matter how much power you use; this charge covers the upkeep of all the poles and wires that get the energy to your front door.
Key Charges Explained
To make sense of it all, let’s break down the common charges you’ll see on your bill:
- Peak Rates: These are the highest prices, usually kicking in on weekday afternoons and evenings when everyone gets home from work and school and starts switching things on.
- Off-Peak Rates: These are the cheapest rates. They typically apply late at night and over the weekends when overall demand for electricity is at its lowest.
- Shoulder Rates: These are the in-between prices that apply in the periods between peak and off-peak times, like in the late morning or early evening.
This visual shows just how much the average quarterly bill can vary depending on where you live – a huge factor we touched on earlier.

The chart really highlights the gap. You can see residents in the ACT are paying quite a bit more than those down in Tasmania, which just reinforces how much local factors can shape your final bill.
How Demographics Influence Your Bill
Beyond your location and the size of your household, other factors like your age can play a surprising role in what you pay. It makes sense when you think about it – our consumption habits and access to concessions change a lot as we move through different stages of life.
For example, middle-aged Aussies often get hit with the highest energy costs. Those in the 45-54 age bracket face the highest average quarterly bill at $467.40.
At the other end of the scale, those over 65 years old tend to have the lowest average at just $346.90, often thanks to a mix of government concessions and different lifestyle patterns. You can learn more about these demographic energy trends and see the full breakdown for yourself.
Once you get a handle on these individual charges and what influences them, your bill stops being a confusing document and becomes a genuinely useful tool. It shows you exactly where your money is going and, more importantly, where you have the power to make changes and cut your costs.
How Summer and Winter Drive Up Your Costs

Those predictable bill spikes in the middle of summer and the depths of winter aren’t just your imagination. The changing seasons are one of the biggest forces shaping the average energy bill in Australia, turning your home’s heating and cooling systems into the main culprits behind your quarterly costs.
Think of your home’s energy use as having a steady, baseline heartbeat for most of the year. But when extreme temperatures hit, your air conditioner or heater kicks into overdrive. That heartbeat starts to race, and your energy consumption surges right along with it.
It all comes down to the sheer power needed to keep your home comfortable when it’s scorching hot or freezing cold outside. In fact, heating and cooling can be responsible for up to 40% of a typical household’s entire energy bill.
The Real Cost of Staying Comfortable
The gap between different cooling choices shows just how quickly these costs can stack up. Firing up a standard ducted air conditioning system can set you back anywhere from $2.50 to $3.50 per hour. A humble ceiling fan? Just a few cents.
Over a long, hot summer, relying solely on the air con can easily add hundreds of dollars to your bills. This is where small, conscious decisions can have a huge impact.
Simple upgrades like updating window screens to reduce summer heat can also play a role in keeping your home cooler and your expenses down. It’s a small change that contributes to the bigger picture of efficiency.
Winter throws a similar punch. While many newer Australian homes use efficient reverse-cycle air conditioning for warmth, older electric heaters are notoriously power-hungry and can drive up costs just as fast as summer cooling.
Managing your thermostat is one of the most powerful moves you can make to control seasonal energy spikes. Every single degree you adjust makes a real difference to your final bill.
Smart Thermostat Strategies for Savings
You don’t have to shiver or sweat to get your bills under control. A few simple, strategic tweaks to your thermostat settings can lead to some serious savings over a season.
Try these easy adjustments:
- In Summer: Set your air conditioner to 24°C or 25°C. It’s a comfortable temperature that stops the unit from having to work flat out.
- In Winter: Aim for a cosy 18°C to 20°C. Instead of cranking the heat, just add an extra layer of clothing.
By understanding how summer and winter affect your usage, you can see these higher bills coming and take steps to manage them. This puts you back in control of your budget year-round, so you’re never caught off guard by a seasonal price shock.
Actionable Tips for Lowering Your Energy Bill
Knowing what the numbers on your power bill mean is one thing. Putting that knowledge to work is where the real savings kick in. You don’t need to overhaul your life to see a difference, either. Often, it’s the small, consistent habits that add up, chipping away at the average energy bill right across Australia.
Many of these tweaks cost absolutely nothing and you can start them today. It really just comes down to being a bit more mindful of how and when you use power, turning simple actions into powerful, money-saving routines.
Simple Changes in the Kitchen
The kitchen might be the heart of the home, but it’s also a major energy hotspot. Between the fridge humming away 24/7 and all the cooking appliances, there are plenty of chances to trim your usage without giving up any convenience.
Here are a few easy wins:
- Use the right tool for the job. Your microwave uses up to 75% less energy than a conventional oven, making it perfect for reheating leftovers or cooking smaller meals.
- Keep your fridge and freezer full. An empty fridge has to work much harder to cool down all the warm air that rushes in every time you open the door. A full one holds its temperature with a lot less effort.
- Thaw frozen food in the fridge. This not only thaws food safely but also helps keep the fridge cool, giving its compressor a bit of a break.
These simple shifts in behaviour don’t cost a cent, but together they steadily reduce your daily energy consumption. The result? Noticeable savings on your quarterly bill.
Living Room and Entertainment Fixes
Living areas are prime suspects for hidden energy waste, mostly thanks to something called “vampire power.” This is the electricity that your gadgets sip on even when they’re switched off or in standby mode. This phantom load can be responsible for up to 10% of your household’s entire electricity use.
Luckily, the best defence is also the simplest: switch your appliances off at the wall. This one action completely cuts the power, stopping televisions, gaming consoles, and sound systems from drawing any standby power at all. Using a power board with a single switch makes this even easier, letting you shut down multiple devices in one go.

The Long-Term Solution: Solar Power and VPPs
While small habits can certainly trim your bills, achieving real energy freedom means looking at smarter, more permanent investments. Solar panels are the most powerful long-term strategy out there, turning your roof into a private power station and cutting your reliance on the grid for good.
Think of solar as a shield against unpredictable electricity prices. The panels soak up sunlight and turn it into electricity to run your home during the day, absolutely free. This simple act can slash your power bill, and in many cases, wipe it out completely.
It’s a significant investment, of course, and the upfront cost is a real consideration. For anyone weighing up the numbers, understanding solar panel payback periods is the first step to seeing how the long-term financials stack up. Thanks to Australia’s abundant sun and government incentives, that payback timeline is often shorter than you’d think.
And what about the extra power your system makes? It doesn’t go to waste. Through feed-in tariffs, you sell this surplus energy back to the grid for a credit on your bill. Just like that, your home goes from being a simple energy user to an active player in the market.
The Next Step: Virtual Power Plants
Solar panels are just the start. The next evolution in home energy is the Virtual Power Plant (VPP), a clever concept that links a network of homes with solar batteries, allowing them to work together as one big, coordinated power source.
Picture it as a community-based ‘internet of batteries’. When the grid is under strain during peak demand—say, a scorching summer afternoon when every air conditioner in the state is blasting—the VPP can collectively sell stored energy from participating homes back to the grid when prices are highest.
This setup benefits everyone:
- For homeowners: You earn real money by selling your stored solar energy when it’s most valuable, on top of the savings you already make on your bills.
- For the grid: It gets a reliable shot of clean energy to prevent blackouts and reduces the need to fire up expensive, polluting power stations.
- For the community: It helps build a more stable, resilient, and green energy network for the whole neighbourhood.
A VPP transforms your solar and battery system from a passive savings tool into an active, income-generating asset. You get paid to support the grid, further reducing your overall energy costs and accelerating your return on investment.
These technologies are no longer complex, niche projects for early adopters. They are accessible, smart investments that offer a clear path towards a future with lower bills and far more control over your energy. To see how it works in practice, you can explore the details of joining a Virtual Power Plant and find out how it could fit into your home’s energy strategy.
Got Questions? We’ve Got Answers
Digging into your power bill can feel like deciphering a secret code. A few straightforward answers can clear things up and put you back in control. Here are some of the most common questions we hear from homeowners trying to get a handle on their energy costs.
What’s the Difference Between Electricity Tariffs?
Think of a tariff as the pricing plan for your power. Getting it right is one of the quickest ways to save money, because it matches how you’re charged to how you live.
There are three main types you’ll come across:
- Single Rate Tariff: This is the simplest of the lot. You pay one flat rate for every kilowatt-hour you use, no matter if it’s 3 am or 6 pm. It’s predictable and easy to understand.
- Time of Use Tariff: Here, the price changes depending on the time of day. Power is more expensive during ‘peak’ demand hours (usually late afternoon and evening) and much cheaper during ‘off-peak’ hours (like overnight). If you can shift your heavy appliance use to cheaper times, this tariff can work wonders.
- Controlled Load Tariff: This is a special, cheaper rate for specific high-draw appliances you’re happy to run at off-peak times, like your electric hot water system or pool pump. It’s a separate circuit, giving you a deep discount for being flexible.
The right choice really boils down to your household’s daily rhythm.
Are There Any Government Rebates to Help With Bills?
Absolutely. Both federal and state governments offer a range of rebates and concessions designed to take the sting out of the average energy bill in Australia. These are often aimed at low-income households, seniors, and anyone holding a concession or healthcare card.
Beyond direct bill relief, you’ve also got schemes like the Small-scale Renewable Energy Scheme, which acts as an upfront discount when you install solar panels. It’s always worth heading to your state government’s energy website to see what programs you’re eligible for – you might be surprised.
Taking a few minutes to check for rebates can provide immediate relief on your quarterly bills, making a real difference for eligible households.
How Do I Pick the Best Energy Provider?
Choosing the right energy provider is about more than just finding the cheapest advertised price per kilowatt-hour (kWh). That headline number can be misleading.
To get the full picture, you need to compare the daily supply charge (the fixed fee you pay just to be connected), any sign-up deals or discounts, the contract terms, and, importantly, any exit fees if you decide to leave.
Your best bet is to use a government-run comparison tool like Energy Made Easy. It cuts through the marketing noise and lays out all the offers available where you live, helping you find a plan that genuinely fits your usage habits for the best long-term value.
