Growth Pains and Policy Gaps: How the Sunshine Coast Stacks Up Against the World's Fastest-Growing Coastal Cities

The Sunshine Coast is growing faster than almost any other metropolitan area in Australia, and the infrastructure, housing and environmental decisions being made right now will define the region for decades. Population growth in the corridor between Caloundra and Noosa has been running well ahead of national averages for several years, drawing comparisons, not always flattering, to similarly overwhelmed coastal cities across the world.

What makes the Sunshine Coast's situation distinct is the collision of several pressures at once: a major hospital expansion still under way at Birtinya, a brand-new CBD being carved out of former wetlands in Maroochydore, an international airport at Marcoola actively courting new long-haul routes, and a short-term rental market that has hollowed out affordable housing stock from Mooloolaba to Noosa Heads. Few coastal cities anywhere have faced all four simultaneously.

The Short-Term Rental Problem Is Not Unique, But the Response Matters

Cities like Lisbon, Barcelona and Byron Bay have each grappled with the same short-term rental spiral: tourism platforms drive up returns for property owners, long-term rental supply tightens, workers can no longer afford to live where they work, and essential services, hospitality, aged care, health, struggle to staff up. The Sunshine Coast Regional Council has been consulting on a local law framework to regulate platforms such as Airbnb and Stayz, a process that mirrors legislative moves already taken in Queensland's Noosa Shire, which introduced a 50 per cent cap on short-term rental properties in residential zones in late 2023.

Noosa's approach drew international attention precisely because it was one of the first local governments in Australia to impose a hard cap rather than relying on registration alone. The Sunshine Coast, with a far larger and more varied urban footprint stretching from Beerwah in the hinterland to the Mooloolah River catchment, faces a harder political task trying to replicate that model across diverse suburbs and income levels. Kelowna, British Columbia, struck a similar balance in 2024 by restricting short-term rentals to principal residences only, a policy that cut available holiday listings by roughly a third within six months, according to provincial government data released that year.

Council's short-term rental working group is expected to report back to elected members before the end of the third quarter of 2026, with any new local law unlikely to take effect before mid-2027 at the earliest.

Hospital, CBD and Airport: The Infrastructure Trifecta

Sunshine Coast University Hospital at Birtinya opened in 2017 with around 450 beds. The expansion project now under way is designed to significantly increase that capacity, responding to a catchment population that has grown sharply since the original facility was commissioned. Health Infrastructure Queensland is overseeing the works, which are being staged to keep the existing facility fully operational throughout construction.

A few kilometres north, the Maroochydore City Centre project, managed through SunCentral Maroochydore, a company established by the Sunshine Coast Council, represents one of the largest greenfield CBD developments attempted by any regional city in Australia. The 53-hectare site already has permanent residents, a functioning commercial precinct along First Avenue, and a dedicated fibre-optic network buried under its streets. By comparison, Townsville's CBD revitalisation project, which also began in earnest around 2017, remains centred on retrofitting existing urban fabric rather than building from scratch.

Sunshine Coast Airport, operated by Airports Worldwide from its base at Marcoola, has been actively seeking to expand its international footprint since the terminal upgrade completed in 2020. The airport sits roughly 10 kilometres north of Maroochydore and is one of only a handful of regional Australian airports certified for international passenger operations.

For residents watching all of this unfold from suburbs like Bokarina, Wurtulla or Birtinya itself, the practical questions are immediate: Will the new CBD attract the jobs and services to reduce commuter pressure on the Bruce Highway? Will hospital expansion keep pace with the retiree population moving in from Brisbane and Sydney? And will short-term rental reform come quickly enough to keep rental prices within reach of the nurses and construction workers the region urgently needs? The answers, based on the pace of policy development so far, are probably not coming before the end of the decade.
