The cost of living has dominated Australian dinner table conversations for the past three years, and with good reason. While inflation has eased from its 2023 peak, the cumulative impact of years of rising prices means that everyday life is significantly more expensive than it was before the pandemic. But the experience varies enormously depending on where you live. A $100,000 salary in Sydney buys a very different lifestyle than the same income in Adelaide or Hobart. This guide compares the real costs across all eight states and territories to help you understand where your dollar goes furthest.
Rent: The Biggest Divide
Housing costs are by far the largest expense for most Australian households, and the variation between states is dramatic. As of early 2026, median weekly rents for a three-bedroom house in capital cities are approximately:
- Sydney: $750/week ($39,000/year)
- Canberra: $650/week ($33,800/year)
- Melbourne: $580/week ($30,160/year)
- Brisbane: $560/week ($29,120/year)
- Perth: $550/week ($28,600/year)
- Hobart: $510/week ($26,520/year)
- Darwin: $500/week ($26,000/year)
- Adelaide: $500/week ($26,000/year)
The gap between Sydney and Adelaide is $13,000 per year — money that could go towards savings, investments, or simply a better quality of life. For a two-income household, the differential is even larger when you factor in the higher rents for larger properties in premium suburbs.

Groceries and Household Essentials
The cost of a weekly grocery shop has risen by approximately 15% to 20% since 2022, and while the rate of increase has slowed, prices have not come back down. Based on ABS data and consumer surveys, the average weekly grocery spend for a family of four is approximately:
- Sydney: $320-$380
- Melbourne: $290-$350
- Brisbane: $280-$340
- Perth: $290-$350
- Adelaide: $270-$320
- Hobart: $280-$330
- Canberra: $300-$360
- Darwin: $340-$400
Darwin's high grocery costs reflect the tyranny of distance — most fresh produce is trucked or flown in from southern states. Sydney's premium reflects higher retail rents that are passed on to consumers. Adelaide and Hobart remain the most affordable for food, benefiting from local agricultural production and lower commercial rents.
Transport and Fuel
Transport costs vary significantly depending on whether you drive or use public transport — and where you live relative to your workplace. Average annual transport costs (including fuel, registration, insurance, and maintenance or public transport fares) by capital city:
- Sydney: $8,500-$12,000 (higher public transport usage offsets some car costs)
- Melbourne: $8,000-$11,000
- Brisbane: $9,000-$12,500 (more car-dependent with longer commutes)
- Perth: $9,500-$13,000 (highest car dependence of any capital)
- Adelaide: $7,500-$10,000
- Hobart: $7,000-$9,500
- Canberra: $8,500-$11,500
- Darwin: $8,000-$11,000
Petrol prices at the time of writing average $1.85 to $2.10 per litre nationally, with regional areas typically paying 10 to 20 cents more than capital cities. Perth and Brisbane tend to have the most volatile fuel prices due to their pricing cycles. If you are calculating the true cost of a commute, our hourly rate calculator can help you work out what your commuting time is costing you in effective hourly wage terms.
Childcare: The Hidden Budget Buster
For families with young children, childcare is often the single largest household expense after housing. The average daily fee for centre-based long day care varies significantly by state:
- Sydney: $155-$185/day
- Canberra: $145-$170/day
- Melbourne: $135-$165/day
- Brisbane: $125-$150/day
- Perth: $120-$145/day
- Adelaide: $110-$135/day
- Hobart: $105-$130/day
- Darwin: $115-$140/day
The Child Care Subsidy (CCS) covers between 24% and 90% of fees depending on family income, with the maximum subsidy available to families earning under $80,000 combined. For a family with two children in care three days per week in Sydney, the out-of-pocket cost after the CCS can still exceed $30,000 per year. Use our Family Tax Benefit calculator to estimate your total government support including CCS and Family Tax Benefits.
Energy and Utilities
Electricity and gas prices have been a major source of household pain, particularly in southeastern states. Average annual electricity bills for a three-person household:
- South Australia: $2,400 (highest average retail rates in the country)
- NSW: $2,100
- Queensland: $1,800 (government rebates keeping costs lower)
- Victoria: $2,000
- Tasmania: $2,200
- WA: $1,700 (regulated market with lower prices)
- ACT: $1,900
- NT: $1,600 (subsidised prices)
Gas prices add another $600 to $1,200 per year for households with gas connections, though many newer homes are built all-electric as the economics of rooftop solar and battery storage continue to improve. Government energy rebates — which vary by state — can offset $300 to $500 of annual costs for eligible households.
Putting It All Together: The Total Cost Comparison
When you combine housing, groceries, transport, utilities, childcare, and other essentials, the total cost of living for a family of four (two adults, two children) by capital city is approximately:
- Sydney: $130,000-$160,000/year
- Canberra: $115,000-$140,000/year
- Melbourne: $110,000-$135,000/year
- Brisbane: $105,000-$130,000/year
- Perth: $100,000-$125,000/year
- Darwin: $100,000-$125,000/year
- Hobart: $95,000-$115,000/year
- Adelaide: $90,000-$115,000/year
The $40,000 to $45,000 gap between Sydney and Adelaide is striking. On a household income of $180,000, a Sydney family might be scraping by while an Adelaide family on the same income is saving $30,000 or more per year. This is why interstate migration to Queensland, South Australia, and Tasmania has been booming — people are voting with their feet.

Where Does Your Dollar Go Furthest?
Based on the combined cost data and average incomes, the states that offer the best value for money in 2026 are:
- Adelaide, SA: Lowest overall costs combined with rapidly improving job market and lifestyle amenities. The winner for families seeking affordability without sacrificing urban convenience.
- Brisbane, QLD: Strong job market, reasonable costs (outside the inner city), and generous first home buyer support. The post-Olympic infrastructure spending is transforming the city.
- Hobart, TAS: Cheapest for groceries and childcare, though the job market is smaller. Best suited to remote workers or those in niche industries.
- Perth, WA: Mining-adjacent incomes combined with moderate living costs make Perth excellent value for those in the right industries.
The most expensive cities — Sydney and Canberra — do offer higher average salaries, but the cost premium typically exceeds the wage premium for middle-income earners. High-income professionals (lawyers, surgeons, senior executives) may find the salary uplift in Sydney worthwhile, but for the median worker, the numbers favour more affordable cities.
The Bottom Line
The cost of living in Australia varies enormously depending on where you plant your flag. A strategic relocation — even within the same state — can save a household tens of thousands of dollars per year. Before making any major financial decisions, run your numbers through our salary calculator to understand your after-tax income, then compare it against the real costs in your city. The gap between what you earn and what you spend is the only number that truly matters for building long-term wealth.
