Sunshine Coast population surge strains hospitals, housing in 2026

The Sunshine Coast is adding roughly 10,000 new residents every year. That single figure, drawn from the Australian Bureau of Statistics' most recent regional population projections, underpins almost every infrastructure, housing and environmental argument currently playing out across the region, from Caloundra in the south to Coolum Beach in the north.

Population growth of that scale does not happen quietly. It shows up in hospital wait times, rental vacancy rates, development applications and the length of the queue at the Maroochydore City Centre construction hoarding on Horton Parade. The Sunshine Coast Council's own planning documents forecast the regional population will breach 500,000 by 2041, up from approximately 370,000 today. That is a 35 per cent increase in under two decades, and the public services expected to absorb it are, in several key areas, already behind.

Hospital Expansion and the Infrastructure Gap

Sunshine Coast University Hospital at Birtinya is the clearest example of an institution racing to keep pace. The hospital opened in 2017 with 450 beds. A $1.55 billion expansion currently under construction is intended to lift that to 738 beds by late 2028, an increase of roughly 64 per cent. Queensland Health figures show the hospital's emergency department recorded more than 85,000 presentations in the 2024-25 financial year, a number that has grown by about 8 per cent annually since the hospital opened. At that rate, the expanded facility will be operating at near-capacity within five years of completion.

The bed count matters because the Sunshine Coast has one of the oldest median ages of any high-growth region in Queensland, sitting at 40.1 years compared to a state median of 37.8. Older populations use acute hospital services at higher rates. The dual pressure of raw population growth and an ageing demographic profile is what makes the SCUH expansion more urgent than the headline dollar figure suggests.

Short-Term Rentals, Vacancy Rates and the Housing Crunch

The rental market data is equally stark. The Real Estate Institute of Queensland reported a vacancy rate of just 0.8 per cent across the Sunshine Coast local government area in the March 2026 quarter. A healthy rental market typically sits at or above 3 per cent. Median weekly rent for a three-bedroom house in Buderim reached $680 in June 2026, compared to $495 for the same property type in June 2023, a 37 per cent rise in three years.

Short-term rental platforms are a significant part of the story. Data compiled by short-term rental analytics firm AirDNA estimated there were approximately 7,400 active short-term rental listings on the Sunshine Coast as of May 2026, concentrated heavily in Noosa Heads, Coolum Beach and Mooloolaba. Queensland's mandatory short-term rental registration scheme, which came into force on 1 September 2025 under the Short-term Rental Accommodation Act, has so far registered around 5,200 of those properties, meaning an estimated 2,200 listings may still be operating outside the compliance framework. The Sunshine Coast Council's planning team has flagged enforcement as a priority for the second half of 2026.

The Maroochydore CBD project, now in its seventh year of staged construction along the Cornmoran Drive and First Avenue precinct, has attracted $3.2 billion in committed private investment according to SunCentral Maroochydore, the government-owned corporation overseeing the development. Approximately 34 hectares of the 53-hectare master-planned site remain under active development, with the commercial and residential towers along the new canal waterway expected to deliver around 2,700 dwellings over the next decade.

For residents navigating all of this in practical terms: the council's Development Tracker portal, accessible via the Sunshine Coast Council website, allows anyone to monitor live planning applications by suburb. The state government's rental assistance program, RentConnect, operates a Maroochydore service centre at 6 Duporth Avenue for households in housing stress. And SCUH's emergency department expansion wing is scheduled to open its first stage in March 2027, which should ease some of the current pressure on after-hours GP clinics across the Kawana and Bokarina corridors.
