Sydney's Internal Migration Crisis: Four Years, 154,589 Residents Lost, Dead Last Nationally

Sydney has lost 154,589 residents to internal migration over four years — more than any other Australian region. We break down where they're going and why.

Key takeaways

• Sydney is #102 of 102 nationally for net internal migration — dead last out of every measured Australian region
• 154,589 residents lost to the rest of Australia over four years — more than Melbourne and Adelaide combined
• The biggest destination isn't Brisbane — it's regional NSW. Nearly half of Sydney leavers stay within the state, spreading to the Central Coast, Wollongong, Newcastle, and the Southern Highlands
• The apartment-to-house ratio is 4 to 1 — Find a Mover platform data shows Sydneysiders leaving are overwhelmingly upsizing, trading apartments for houses they couldn't afford to buy in the city
• 2025 is the smallest loss in four years — the bleed is moderating but every single corridor remains deeply negative. No reversal is in sight
• Sydney has only five net-gain corridors out of 51 measured, totalling a combined +516 residents. The lone meaningful exception is Hobart

The latest ABS Internal Migration figures are out (the March 26 release) and Sydney continues losing people. Not in a small way,, and not just for a single year. Over the four years from 2022 to the end of 2025, 154,589 residents left Sydney for the rest of Australia. No other region in the country comes close to those kind of figures. 

New analysis of the latest Australian Bureau of Statistics Regional Internal Migration Estimates (released in March 26), combined with moving data from findamover.com.au, maps not just the scale of Sydney's internal migration outflow, but where its residents are going, what they're leaving behind, and what they're moving into when they get there. The picture that emerges isn't just about Sydneysiders leaving for Queensland or affordability. It's about a city systematically pushing out its own residents, suburb by suburb, in every direction.

Four years of persistent outflow

Sydney's MoveFlow Index of 0.65 means that for every 100 people who arrive, roughly 65 do — or put another way, for every three people who leave, fewer than two arrive to replace them. That ratio has held below 0.70 for four consecutive years, with no sign of structural reversal.

Two things stand out in the numbers. First, arrivals fell sharply after 2022 — from 87,333 down to around 62,000 — and have stayed there. The pipeline of people choosing to move to Sydney is not recovering. Second, departures have eased somewhat from their 2022 peak of 128,785, but at 94,821 in 2025 they remain nearly 35% above arrivals. Sydney is not close to break-even on any measure.

How Sydney compares nationally

What the headline comparison also reveals is something less reported: only two of Australia's eight capital cities are gaining residents domestically. Brisbane and Perth have been net gainers every single year across the four-year period. Every other capital — Sydney, Melbourne, Adelaide, Canberra, Darwin, and Hobart — is a net loser. And critically, Canberra, Darwin, and Hobart all flipped from near-balanced in 2022 to consistent losses from 2023 onwards, mirroring Sydney's structural pattern at a smaller scale.

The smaller capitals tell a quietly alarming story of their own. Canberra, Darwin, and Hobart were all near-balanced in 2022, then tipped negative in 2023 and have not recovered. Hobart ranks #98 of 102 nationally — fifth worst in the country despite being a state capital. Darwin ranks #90. These are not struggling regional towns. They are the economic and administrative centres of their respective states and territories, and they are losing residents to the rest of Australia year after year. The pattern that Sydney represents at scale has replicated itself in miniature across the entire southern and northern periphery of the country.

Where Sydney's residents are actually going

The dominant narrative around Sydney's population loss points to Queensland — retirees heading to the Gold Coast, families relocating to Brisbane. The data tells a more complicated story. Queensland is certainly a factor, but it is not the primary destination. The single biggest outlet for Sydney's departing residents is regional NSW, and it isn't close.

In 2025, nearly 44% of Sydney's departures stayed within NSW, spreading across the Central Coast (8,514 people), Wollongong (5,585), Newcastle (4,651), the Southern Highlands (3,844), and the Mid North Coast (3,501). The Central Coast alone absorbed more Sydneysiders than the entire state of Queensland. This is not a long-distance migration story. It is Sydney's housing pressure radiating outward into its own periphery.

Melbourne, perhaps counterintuitively, is the single largest destination by individual region — 12,035 people in 2025. Brisbane ranks second (9,359). But the Sydney-Melbourne relationship is a two-way corridor, not a one-way exodus: Melbourne also sends 8,800 people to Sydney each year, making the net loss to Melbourne just 3,235. The Sydney-Brisbane corridor is far more one-directional — 9,359 leave for Brisbane, 5,725 arrive from it, a net of -3,634.

The apartment-to-house exodus

The ABS data tells us how many people are leaving. Find a Mover's platform data tells us what they are leaving for — and the pattern is striking. Analysis of outbound moves recorded on the platform over five years reveals that Sydneysiders leaving the city are overwhelmingly upsizing when they get to their destination.

Apartment-to-house moves outnumber house-to-apartment moves by nearly four to one. The most common single transition is house-to-house, but the defining story of Sydney's outbound migration is people leaving apartments behind and arriving into houses somewhere else. This is the housing affordability narrative rendered in removalist data: people who have saved in Sydney, or sold, and are using that capital to buy the property type that Sydney's market has priced out of reach.

The reverse flow — people moving from a house into a Sydney apartment — is real but marginal. It captures a specific cohort: retirees downsizing into city living, or professionals taking roles that require proximity. But it is outnumbered roughly four to one by the people going the other way.

Who is leaving — and who is arriving

Find a Mover's platform data reveals two distinct groups driving Sydney's outbound flow, visible in the origin suburbs of people booking removalists out of the city.

The first is what might be called the inner-city belt: Surry Hills, Newtown, Leichhardt, Paddington, Redfern, Erskineville, Coogee, and Bondi. These are suburbs that became expensive over the past decade and are now pushing out the renters and younger owners who made them desirable in the first place. This is the same demographic that drove Melbourne's inner-north — Brunswick, Northcote, Fitzroy — into prominence a decade earlier. The parallel is not coincidental.

The second group is the outer-suburban family belt: Blacktown, Penrith, Parramatta, Westmead, Kellyville, and Schofields. These are the growth corridors that were supposed to offer Sydney's affordable alternative. They are now also losing people — families who bought on the fringe and have decided that regional NSW, Queensland, or Melbourne offers a better combination of price and liveability than staying put.

On the inbound side, the pattern is different. People arriving in Sydney are heading primarily to the CBD, Parramatta, and the inner suburbs — a mix of young professionals, international arrivals, and inter-state movers taking up roles in Sydney's financial, professional, and tech sectors. Melbourne is the dominant source of interstate arrivals, contributing nearly three times as many inbound moves as Brisbane.

Has it peaked?

The 2025 data offers a small but genuine signal of moderation. Sydney's net loss of -33,520 in 2025 is the smallest in four years, down from a peak of -41,452 in 2022. Every major corridor narrowed between 2024 and 2025 — Brisbane by 949, Melbourne by 756, the Gold Coast by 841. No corridor reversed, but all of them shrank.

Find a Mover's platform data is consistent with this picture: the outbound-to-inbound ratio has stayed in the 1.46 to 1.68 range every single year for five years. The numbers fluctuate but the direction does not. Moderation is not the same as reversal, and Sydney's internal migration story remains firmly in negative territory by any measure.

What this means for Sydney

The affordability crisis is self-reinforcing

Sydneysider's who leaves to buy a house elsewhere are more than likely to have tried and failed to make Sydney's property market work on their terms. The apartment-to-house ratio in outbound moves is the clearest evidence of this: people are not leaving Sydney because they want to. They are leaving because the property type they want — a house, a yard, space for a family — is financially out of reach. Until that changes, the pipeline of departures will likely continue.

Regional NSW is absorbing the pressure — and may not cope indefinitely

The Central Coast, Wollongong, Newcastle, and the Southern Highlands are functioning as Sydney's pressure valve. Combined they absorbed around 27,000 Sydney leavers in 2025 alone. The infrastructure, housing supply, and services in each of these regions face their own capacity constraints.

Sydney's population is still growing — just not from Australians

It is worth stating clearly: Sydney's total population is not shrinking. International migration continues to add roughly 30,000 net residents per year, more than offsetting the domestic outflow. But population growth through international migration has a different character to organic domestic growth — different demographics, different housing demands, different patterns of consumption. The -154,589 domestic outflow matters because it represents the revealed preferences of people who already know Sydney, have lived there, and chose to leave.

Four consecutive years at the bottom of the national rankings, a MoveFlow Index that has not approached 0.70 since 2022, and a platform outbound ratio that has an average of 1.57:1 for five years — the data from both findamover.com.au and the ABS point in the same direction. Sydney's internal migration story is not one of moderation. It is one of a city that has been, for four years, telling a significant share of its residents that they would be better off somewhere else — and those residents are listening.
