Sunshine Coast's housing crunch: How this region stacks up against the world's fast-growing coastal cities

The Sunshine Coast Regional Council approved just 4,200 new dwellings in the 2024-25 financial year against a demand figure its own planning department estimated at closer to 6,500. That gap, roughly 2,300 homes, sits at the centre of a debate that is no longer local. It is playing out in coastal growth corridors from New Zealand's Queenstown Lakes district to Portugal's Algarve, and the policy tools on offer are remarkably similar everywhere. What differs is whether governments actually use them.

The pressure arrived here faster than anyone planned for. The region's population crossed 400,000 during 2025, a milestone the council's 2017 growth projections did not anticipate until 2031. The Sunshine Coast University Hospital expansion at Birtinya added roughly 1,400 construction and permanent jobs between 2023 and mid-2026, pulling workers into a market already strained by post-pandemic sea-changers. Median house prices in Buderim held above $950,000 through the first quarter of 2026, according to CoreLogic data, while unit rents in Cotton Tree touched $680 a week, figures that would have been unthinkable in 2019, when the same stock moved at $420.

What other fast-growing coastal cities have tried

Santa Barbara, California, a city of comparable scale and coastal amenity, hit similar price walls in the early 2010s and responded by mandating inclusionary zoning: any development above eight dwellings must include 15 percent affordable units, with density bonuses offered in exchange. The city now adds around 200 affordable homes annually from that mechanism alone. Queenstown Lakes District in New Zealand passed its own Housing Accords and Special Housing Areas legislation in 2014, fast-tracking approvals in designated growth zones and cutting consent times from 18 months to under six. Neither approach is perfect, but both produced measurable supply within four years of adoption.

The Sunshine Coast's equivalent tool, the Priority Development Area framework administered through Economic Development Queensland, covers the Maroochydore City Centre, where the new CBD grid between Duporth Avenue and Cornmeal Creek is still under active construction, but it does not extend to the suburban middle ring where demand is most acute. Suburbs like Caloundra West and Bokarina, both earmarked for medium-density infill under the 2022 Planning Scheme review, have seen approval rates lag because of repeated vegetation offset disputes. The Sunshine Coast Environment Council has flagged 14 separate objections to residential rezonings since January 2025, invoking the council's Biodiversity Offset Policy. That policy, while environmentally defensible, has no equivalent holding mechanism to ensure displaced density lands somewhere else in the network.

Short-term rental regulation is the other variable. The Algarve municipality of Loulé capped new Airbnb licences in its historic villages in 2023 and reported a 9 percent increase in long-term rental listings within 12 months. The Sunshine Coast had approximately 7,800 active short-term rental listings as of March 2026, according to AirDNA tracking data, concentrated heavily around Noosa Heads, Mooloolaba Esplanade, and Alexandra Headland. Queensland's state government has still not introduced a mandatory registration scheme for short-term rentals, leaving councils without the data infrastructure to act even if they wanted to.

What has to change, and when

The council's next growth management strategy is due for public exhibition in September 2026. Planning officers are understood to be modelling three scenarios: a status-quo trajectory, a transit-oriented density push around the Sunshine Coast Airport precinct at Marcoola, and a hybrid that pairs infill incentives with a formal short-term rental register. The Marcoola corridor option would align with the airport's international route expansion, which added Singapore and Kuala Lumpur services in early 2026 and is expected to increase land values in that corridor by a further 8-12 percent over three years.

For households currently in the market, the practical reality is that relief from supply additions is at least 18 months away under the most optimistic council timelines. Renters facing lease renewals before mid-2027 should seek early engagement with tenancy assistance services through Unitywater's community referral program or the Sunshine Coast Community Legal Centre on Aerodrome Road, Maroochydore, both of which have expanded housing advisory capacity this year. The planning fight, meanwhile, will largely be won or lost in that September exhibition period, which is also when the public gets its formal say.
