Your mortgage repayment is not the only bill that lands every month
, home and contents insurance, , electricity, and gas add thousands of dollars per year to the cost of owning a home. If you budget only for your mortgage repayment, you will be short every single month. This step breaks down what each recurring bill costs, how they vary by location, and how to plan for them before settlement rather than after.
- The national average premium rose 14% in a single year, from $2,452 to $2,795 across 2025 .
- 1.6 million Australian households now spend more than four weeks of gross income on home insurance, a threshold the Actuaries Institute calls "affordability stress" .
- Combined annual ownership costs (rates, insurance, water, utilities) typically run $6,315 to $13,400 — $525 to $1,115 per month on top of the mortgage.
Insurance is only one of several recurring bills that hit every homeowner. When you stack council rates, water, and utilities on top, the gap between your repayment and your real monthly cost of ownership becomes the gap between a budget that holds and one that blows out.
Council rates fund your street, and every property owner pays them
Every property owner in Australia pays council rates. These are levied by your local council to fund roads, footpaths, waste collection, parks, libraries, and other community services. Council rates make up about 50% of local council income and roughly 3.6% of total government tax revenue .
Your council calculates rates by multiplying your property's valuation by a figure the council sets each year based on its budget. If the total value of all rateable properties in your council area is $2.38 billion and the council needs to raise $10 million, the rate in the dollar would be about 0.42 cents. A property valued at $250,000 would pay roughly $1,050 .
The valuation method varies by state. NSW and Queensland use — the value of the land only, without buildings. Victoria uses — the market value of the land plus all buildings and improvements. Western Australia uses gross rental value .
There is no single national average because each of Australia's 500-plus councils sets its own rate independently. However, typical residential council rates range from about $1,200 to $3,500 per year depending on property value and location . South Australian households pay around $2,028 per year on average . Most councils bill quarterly, though some offer monthly payment options. Pensioners and healthcare card holders may qualify for concessions — up to $250 per year in NSW, or a 20% subsidy on gross rates in Queensland .
Home and contents insurance is the cost that shifts most with location
covers the physical structure of your home — walls, roof, floors, fixtures — against damage from events like fire, storm, or flood. covers your belongings inside the home. Most homeowners buy a combined home and contents policy.
If you have a mortgage, your lender will almost certainly require you to hold building insurance as a condition of the loan . You will need to provide a — proof of cover — before settlement. This is not optional. If you own a strata property, the owners corporation arranges building insurance for the common property and building structure, so you typically only need contents insurance .
The cost of home and contents insurance varies dramatically by state. As of January 2026 :
State/Region | Average Annual Premium |
|---|---|
ACT | $2,903 |
SA | $2,318 |
WA | $2,590 |
Victoria | $3,033 |
Tasmania | $2,964 |
NSW | $4,852 |
South Queensland | $4,711 |
North Queensland | $5,074 |
NT | $4,914 |
What drives your premium up: location in a flood, cyclone, or bushfire zone; higher rebuild cost; older construction; timber framing; proximity to the coast; and higher sum insured. What brings it down: newer build, brick construction, security systems, higher excess, and bundling home and contents together.
Water and utilities scale with how you live in the home
Water costs have two components: a fixed service charge (you pay this regardless of how much water you use) and a usage charge based on how many kilolitres you consume. As a renter, your landlord typically covers the fixed charge and you may or may not pay for usage. As a homeowner, you pay both.
Average annual water bills vary by city :
City | Average Annual Water Bill |
|---|---|
Melbourne | $716 – $1,292 |
Sydney | ~$1,388 |
Brisbane | ~$1,480 |
The range in Melbourne reflects household size — a single person pays less, a family of four pays more. Sydney water prices increased from October 2025, pushing the average household bill to around $1,388 per year . Brisbane's southeast Queensland water and sewerage charges tend to be higher than other capitals due to infrastructure costs.
Electricity is typically the largest utility bill. The average annual electricity cost by state in 2025-26 :
State | Average Annual Electricity Bill |
|---|---|
Victoria | $1,675 |
NT | $1,960 |
Queensland | $2,143 |
WA | $2,200 |
SA | $2,301 |
NSW | $2,370 |
ACT | $2,336 |
Tasmania | $2,480 |
If your home uses gas for heating, hot water, or cooking, add roughly $700 to $920 per year depending on your state. NSW averages about $704 per year for gas, Victoria $720, and Queensland $676 . Western Australia is the cheapest for gas at around $440 per year . Homes with all-electric setups (heat pump hot water, induction cooktop, reverse-cycle heating) avoid gas bills entirely.
What the true monthly cost of owning a home looks like
Here is what a typical homeowner might pay annually beyond their mortgage, using mid-range figures:
Cost | Typical Annual Range |
|---|---|
Council rates | $1,200 – $3,500 |
Home and contents insurance | $2,300 – $5,000 |
Water rates | $700 – $1,500 |
Electricity | $1,675 – $2,480 |
Gas (if connected) | $440 – $920 |
Total | $6,315 – $13,400 |
That is $525 to $1,115 per month on top of your mortgage repayment. At the higher end — realistic for a house in Sydney, Brisbane, or regional Queensland — this is the equivalent of an extra $260 per week.
You need to factor these costs in from the start. When you are calculating how much you can afford to borrow, subtract these running costs from your available income before you set your repayment ceiling.
