In Taylor, one of Gungahlin's newest suburbs and among the fastest-filling patches of Canberra this decade, a father waits at afternoon pick-up outside a primary school where demountable classrooms now sit beside the permanent buildings — added because the school reached capacity faster than planners expected. A short drive away in Bruce, an elderly Gungahlin resident taken by ambulance to Calvary Public Hospital's emergency department joins a queue in a building the ACT government's own budget papers effectively concede is undersized for the district it serves. A bigger, replacement Northside Hospital on the same site has been promised since the 2020 election, but construction is not due to start until 2027-28, and the government's own 2026-27 Budget shows the project still stretching years further into the future (CMTEDD, "A new northside hospital and a more efficient health system", 2023; ACT Budget 2026-27, "Investing in priority infrastructure — a new Northside Hospital"). Both households are living inside the same underlying fact: Canberra's population keeps climbing, the government's own long-range plan says it will keep climbing for another forty years, and in the suburbs growing fastest, the schools, hospitals and transport meant to arrive with the rooftops are, on the government's own timetable, still catching up.
What the government did
The ACT's population passed 482,000 in December 2024 and grew by around 6,500 people, or 1.3 per cent, in the year to September 2025 — a pace that has moderated considerably from the boom of the mid-2010s, when the Territory added more than 12 per cent to its population in the five years to 2021, among the fastest growth of any Australian jurisdiction over that period (ABS, Regional population, 2024-25 financial year; ABS, National, state and territory population, Dec-2025; .id (informed decisions) analysis of ABS population data, 2025, secondary source). Recent growth has also changed character: net interstate migration into the ACT has turned negative, meaning more people are now leaving the Territory for other states than arriving from them, with overall growth propped up instead by natural increase and overseas migration. Even so, in September 2025 the government released new long-range projections putting the Territory's population at close to 700,000 by 2050 and above 800,000 by 2065 — growth of roughly 8,000 people a year on average over the next quarter-century, driven mainly by migration rather than births (ACT Treasury, ACT Population Projections 2025–2065, Sep-2025; CMTEDD, "ACT Population Projections: Growth reflected across the City", Sep-2025).
The government's response has been to commit an Infrastructure Investment Program worth $8.1 billion over the five years to 2028-29, including $1.4 billion in the 2024-25 Budget year alone, more than $2.0 billion for public transport, roads and active travel and more than $1.1 billion for education and skills infrastructure across that period (ACT Budget 2024-25, Infrastructure Investment Program papers). The single largest piece of that pipeline is the new Northside Hospital on the existing Calvary Public Hospital site in Bruce, now funded to the tune of $1.34 billion over the next seven years — bringing the government's total commitment to almost $1.5 billion over a decade — aimed squarely at a northern corridor (Gungahlin, Belconnen and the new Molonglo Valley suburbs) that the government's own projections say will keep growing fastest (ACT Budget 2026-27, "Investing in priority infrastructure — a new Northside Hospital"). Alongside it, the Education Directorate uses an enrolment-projection model built with the Australian National University's School of Demography, updated annually against a census of ACT schools, to decide where and when to build new schools — a pipeline that has already delivered the new Strathnairn Primary School in Molonglo and a planned school for the new suburb of Whitlam, sized for up to 780 students (ACT Education Directorate, "Expanding and Upgrading Schools for our Growing City", 2025-26).
The strongest case
A small territory building at a scale few others attempt
The government's case deserves to be stated on its own terms before it is tested, because population growth here is, in large part, a vote of confidence rather than a problem to apologise for. Canberra keeps attracting people because it combines the lowest unemployment rate of any state or territory with a Commonwealth public service, two universities and a growing tech sector that draw skilled workers from interstate and overseas — and the government's own projections say migration, not births, will drive almost all future growth (ACT Population Projections 2025–2065, Sep-2025). Faced with that, an $8.1 billion five-year Infrastructure Investment Program is a genuinely large commitment for a jurisdiction the size of the ACT, and it is not simply reactive. The Education Directorate's enrolment model is a rare example of a government trying to build schools ahead of the enrolment wave rather than after it, and it has broadly delivered: public school enrolments grew by around 30 per cent over the past decade, and the system absorbed more than 1,000 additional students in each of six consecutive years, without the widespread portable-classroom crises seen in some faster-growing parts of Sydney or Melbourne (ACT Education Directorate, "Planning for growing enrolments at ACT public schools", 2025-26).
The government can also point to a genuine, decade-spanning record of getting ahead of growth on at least one front: water. After the Millennium Drought exposed how close Canberra came to running dry in the 2000s, the Territory built the Murrumbidgee to Googong Pipeline, commissioned in August 2012 at a cost of $140.5 million, to give Canberra an alternative bulk water source before it was urgently needed (Icon Water, Murrumbidgee to Googong Pipeline project information). That pipeline has barely been drawn on since, and Icon Water is now investing again — this time in a bioreactor upgrade to the Territory's main sewage treatment plant at Lower Molonglo, justified explicitly by forecast population growth and ageing infrastructure over the coming decade (Icon Water, Annual Report 2024-25, Oct-2025). And the Northside Hospital, whatever its delivery timetable, is a genuinely sized response to where the government's own data says growth will be heaviest, not a generic city-wide announcement.
The evidence
Set against that case, the government's own recent Budget shows the response has started to reverse just as the growth curve keeps climbing. In the 2026-27 Budget — barely two years after committing the $8.1 billion five-year infrastructure program — the government announced it would defer and stage $700 million worth of projects over the following four years, citing escalating construction costs and a building industry it says cannot absorb the full pipeline at once (Canberra Times, "Andrew Barr slashes infrastructure pipeline to save $700m", 2026; ACT Budget 2026-27 papers). The projects pushed back sit in exactly the growth areas the government's own case rests on: Casey, one of the newest suburbs in fast-growing North Gungahlin, will wait longer for its promised emergency services station, health centre and indoor sports facility, and the contract to extend light rail from Commonwealth Park to Woden — the next stage of the transport spine meant to serve growth along that corridor — will not be signed until after the 2028 election (Region Canberra, "ACT Budget: Projects deferred in $700m infrastructure windback", 2026; Canberra Times reporting on the 2026-27 Budget).
The health and schools pictures are similarly mixed. The Canberra Hospital's $625 million Critical Services Building, which added 72 emergency treatment spaces to bring the total to 147, opened in August 2024 and had treated more than 100,000 emergency patients within its first year (approx.) — real added capacity, but capacity that appears to have been absorbed quickly rather than banked as headroom (Canberra Health Services, "Canberra Hospital's Critical Services Building Turns One", 2025). Its intended northside counterpart remains years from construction, with main works not due to start until 2027-28 — seven years after the government's 2020 election commitment to build it (CMTEDD media releases, 2023; ACT Budget 2026-27). On schools, the enrolment-projection model the government cites as evidence of foresight has itself proven volatile: Freedom of Information data reported in 2025-26 showed ACT public school enrolments are now projected to fall over the next two years before resuming only slow growth — about 0.5 per cent, or 200 to 300 students — from 2028, and the Education Directorate has already rolled back a planned expansion of Majura Primary School because updated projections no longer justified it, even as growth suburbs such as Whitlam and Molonglo still need schools built from nothing (Canberra Times, "ACT schools face infrastructure decisions amid enrolment dip", 2025-26).
The same Budget that confirmed Canberra is on track for roughly 8,000 more residents a year for the next twenty-five years also deferred $700 million of the infrastructure meant to serve them.
The critique
None of this shows a government that failed to plan. The Population Projections 2025-2065, the ANU-built schools model and the Infrastructure Investment Program are genuine attempts to build ahead of a growth curve the government itself forecasts and largely understands. The problem sits one step further along, in the gap between what the Territory plans and what it can actually afford to deliver on schedule once construction costs and Budget pressures bite — and in that gap, it is consistently the newest, fastest-growing suburbs that wait longest. Land release proceeds on schedule because it is funded largely by the sale of the land itself, through the Suburban Land Agency; the schools, health centres and transport links meant to follow are funded from the general Budget, where they compete with debt service and recurrent spending, and where they are among the first line items to move when costs rise. That asymmetry is visible in the 2026-27 Budget: the government kept releasing land in Whitlam, Molonglo and Gungahlin's newest suburbs on largely the same schedule as before, even as it deferred the emergency services station and health centre promised to Casey and pushed the light rail contract for the Woden corridor past the next election.
The schools evidence cuts a slightly different way, toward the same underlying point: a model can be genuinely evidence-based and still be wrong in both directions within the same few years. The Education Directorate rolled back the Majura Primary expansion because its own projections no longer supported it, while other growth suburbs further out still need schools built from nothing — meaning the ANU-built model reduces the risk of blind overbuilding but does not remove the lag between when a family moves into a new suburb and when the school, health centre or bus route that suburb needs has actually been approved, funded and built. On health, the same pattern holds at larger scale: the Critical Services Building added the single largest slab of emergency capacity in the hospital's history in 2024, and within a year it had already absorbed more than 100,000 patients — evidence the expansion met existing pent-up demand rather than banking headroom against the growth still to come, while its intended northside counterpart will not break ground until at least 2027-28, more than seven years after it was first promised.
The risk to the future
A city planned for 700,000 people, funded a budget cycle at a time
The government's own projections commit it, in effect, to sustaining this pace of school, hospital and transport delivery for a generation, not just for the life of one Budget. If the pattern set by the 2026-27 Budget repeats — a headline infrastructure program announced with confidence, then hundreds of millions of dollars deferred from the very growth suburbs it was meant to serve the moment construction costs or debt pressures spike — the newest parts of Canberra will keep filling with residents years before the schools, health centres and transport lines they were promised actually arrive. The Northside Hospital is the clearest test case: a project the government itself calls its single biggest infrastructure commitment for the rest of the decade has already taken from a 2020 election promise to a 2027-28 construction start, with full delivery further off still. If the government's own top priority moves this slowly, growth suburbs further down the list have limited grounds for confidence that theirs will move any faster.
None of that means the underlying growth strategy — accepting migration-driven growth, planning schools with a demographic model, staging an $8.1 billion capital works program — is the wrong approach; the alternative, refusing growth or leaving it entirely unplanned, would almost certainly serve Canberrans worse. But a plan is only as credible as its slowest-delivered promise, and each Budget that trims the infrastructure pipeline just as the population keeps climbing toward 700,000 makes the next deferral easier to justify and the next resident's wait longer to defend.
