Sunshine Coast's green push: What officials and experts are saying about the region's sustainability future

Sunshine Coast Council's own figures tell the story bluntly: the region's population is projected to hit 500,000 residents by 2041, up from roughly 360,000 today, and planners, ecologists and community advocates are increasingly vocal about whether the infrastructure boom is outpacing the environmental safeguards meant to contain it.

The pressure is acute right now because several major projects are converging simultaneously. The Maroochydore City Centre development, still rising from what was, a decade ago, a golf course off Dalton Drive, is adding thousands of residents and workers to a greenfield site that sits within kilometres of the Mooloolaba estuary and key koala habitat corridors. At the same time, the Sunshine Coast University Hospital precinct at Birtinya continues to expand, and council is under sustained pressure to rezone land across the hinterland fringe.

Experts flag the gap between policy and practice

University of the Sunshine Coast researchers have been tracking land-clearing rates across the local government area for the past three years, and what they are finding is not reassuring. Vegetation clearing approvals on the coastal plain, particularly between Bokarina and Bokarina Beach Boulevard north toward Birtinya, have outpaced the rate of replanting under council's offset programs in each of the past two financial years. Ecologists affiliated with USC's Sustainability Research Centre have told council briefings that the region's koala population, already fragmented between the Caloundra hinterland and the Coolum-Noosa corridor, cannot absorb further habitat loss without targeted intervention beyond what current policy mandates.

Sunshine Coast Environment Council, a peak advocacy group based in Mooloolaba, has been pushing for mandatory biodiversity net-gain requirements to be written into the council's new planning scheme, which is due for a formal review before the end of 2026. The organisation argues that voluntary offset arrangements, where developers pay into a revegetation fund rather than protect habitat in situ, have consistently underdelivered on measurable outcomes. Their submission to council, lodged in May, cites a 2024 state government audit finding that Queensland offset projects statewide restored verified habitat on fewer than 60 per cent of registered sites within the required timeframe.

Council's own Environment and Liveability Strategy, adopted in 2020 and running to 2041, commits the Sunshine Coast to net-zero emissions by 2041 and to protecting at least 50 per cent of the local government area as green space. Officers briefing elected members earlier this year noted the green space target is currently tracking at 47 per cent, close, but not guaranteed, given pending development applications on the urban fringe near Beerwah and along the Doonan-Eumundi corridor.

What the region's decision-makers are focused on next

The practical flashpoints heading into the second half of 2026 include the future of the Caloundra Foreshore master plan, where a community working group has been pushing for stronger dune vegetation protection along Bulcock Beach, and the outcome of a state government review into short-term rental regulation. Ecologists argue that investor-driven short-stay accommodation has intensified development pressure on coastal lots that might otherwise have remained low-density, particularly in Noosa Heads and the northern Sunshine Coast coastal strip approaching Peregian Beach.

The airport is a separate but related thread. Sunshine Coast Airport's international expansion, which added Singapore Airlines connectivity from late 2024, has heightened debate about the environmental footprint of the terminal precinct at Marcoola, which sits adjacent to the Bli Bli wetlands and a listed shorebird roost. Biodiversity offsets associated with the airport's stage-two expansion are currently being audited by the Department of Environment and Science.

For residents watching closely, the most immediate practical signal will come when council publishes its updated planning scheme draft, expected in the September quarter. Environmental groups are urging submission participation before any public notification window closes, pointing out that the last full scheme review in 2014 drew fewer than 400 individual responses, a number unlikely to reflect community sentiment in a region that has grown by more than 80,000 people since then.
