Same Country, different costs: Life in Australia can look very different depending on your postcode – and not just when it comes to the view. From housing and groceries to power bills and petrol, the cost of everyday life shifts noticeably between states. If you're thinking about moving interstate, it's worth doing the maths before the boxes are packed.
Plenty of Aussies are surprised by how much their expenses change when they relocate – even without leaving the country. Between New South Wales, Victoria, Queensland and South Australia, cost differences can add up to thousands of dollars per year.
Sydney vs. Melbourne vs. Brisbane
Recent figures from comparison site Canstar show the average family in Sydney spends around $105,000 annually on living expenses, with rent soaking up the biggest chunk. It’s no secret that Sydney is Australia’s priciest capital when it comes to housing.
In Melbourne, the same family gets by on roughly $75,000, while in Brisbane, the figure drops to about $59,000. The gap comes down to a mix of rental prices, transport, energy rates and day-to-day spending.
That’s why more people are considering moving interstate not just for work or family, but to escape cost-of-living pressures. Young couples and families in particular are rethinking where they want to live and what they can actually afford.
Renting Makes the Biggest Difference
Rent is still the largest expense for most households. A three-bedroom house in Sydney averages around $750 a week, while similar homes in Brisbane sit closer to $600. In Adelaide, you’ll find properties for around $520.
For people working remotely or on flexible rosters, that’s a game changer. With no need to stay close to an office, many are heading to regional areas with more affordable housing. Places like the Sunshine Coast or Hobart are booming, with growing infrastructure, good schools and healthcare – without the big-city price tag.
It’s Not Just the Rent
But: Housing costs are just one piece of the puzzle. Weekly groceries, energy bills, public transport and insurance all vary by state. In NSW, a typical family might spend over $250 a week on food alone. That same shop could be 10 until 15 percent cheaper in parts of Queensland or SA.
Electricity prices also depend on the region and provider. Urban households often have more choice and access to competitive deals, while smaller or remote communities tend to pay more.
Then there are local rates, water bills, childcare fees, car rego and more. When planning a move, it’s smart to look at the whole budget, not just the rental listing.
State Policies and Local Impact
Each state has its own approach to things like taxes, infrastructure, and tenant protections – and that affects the bottom line. Victoria has invested heavily in public transport, which can reduce the need for a second car. Queensland offers lower state charges overall, which shows up in household budgets.
In Western Australia, longer distances and supply chain challenges make groceries and hardware more expensive in some areas. So it’s not just geography that makes a difference, it’s also policy.
These behind-the-scenes differences help explain why some states feel more liveable than others. It's not always about the weather – sometimes it’s about what’s left in your wallet at the end of the month.
The Shift Away from Sydney
Internal migration in Australia is on the rise. ABS figures show tens of thousands of people are leaving New South Wales each year, heading mostly to Queensland and Victoria.
While the high cost of renting plays a major role, many are also looking for a better work-life balance. Smaller cities like Adelaide and regional centres like Launceston are on the radar thanks to their lower costs and more relaxed pace.
Quality of Life Isn’t a One-Size-Fits-All
If you’re weighing up a move, you’ve probably asked yourself: Is it worth it? The answer depends on your stage of life, income and priorities. But if you’re open to change and take the time to compare, you might come out ahead financially and personally.
Quality of life isn’t just about big-city buzz or how many cafes are on your street. It’s also about not having to stretch every dollar. Having room to breathe – financially and otherwise – is part of feeling at home.
Whether it’s a move from Sydney to the Sunshine Coast, or from Melbourne to Hobart, looking at the numbers can help you start your next chapter with confidence. Take time to explore local networks, compare service providers and understand lifestyle perks, because: small details can make a big difference after moving.
