Gold Coast Officials and Scientists Warn the Clock Is Running Out on Sea Level Planning

The Gold Coast's long stretch of beachfront real estate, worth billions in tourism revenue and residential property, faces a measurable and accelerating threat from rising seas, and the experts charged with protecting it say the window for meaningful action is narrowing fast. City of Gold Coast engineers and climate scientists have spent recent months briefing councillors on updated modelling that puts sea level rise at between 0.5 and 0.8 metres above 2000 baseline levels by 2100, a range that places dozens of low-lying streets in Mermaid Beach and Broadbeach Waters in periodic inundation territory within decades.

The timing matters for reasons well beyond the long-term. The 2032 Brisbane Olympics will see major competition held at venues in Coomera and Robina, and infrastructure investment flowing into the Gold Coast between now and then is expected to exceed $2 billion. Planners and environmental advocates argue this is the critical moment to embed climate resilience into those projects, or risk locking in vulnerability for a generation.

What the Experts Are Actually Saying

Griffith University's Cities Research Institute, based at the Southport campus, released a technical brief in May flagging that the current City Plan 2016 coastal hazard overlays are based on data that is now more than a decade old. Researchers there have been urging the council to adopt revised overlays ahead of the next City Plan review, which is expected to begin formal consultation in late 2026. Without updated mapping, they warn, development approvals in places like Hope Island and Hollywell will continue to proceed without adequate flood buffers.

Engineers at the City of Gold Coast's Water and Waste division have pointed to the Palm Beach to The Spit Coastal Management Program as the most active policy framework currently addressing erosion. That program, which has overseen periodic sand nourishment along 35 kilometres of shoreline since 2013, costs the city approximately $8 million per year to maintain. Council officers have told community meetings that the nourishment schedule alone cannot compensate for a sustained rise in mean sea level, it buys time, not permanent protection.

Surfers Paradise Beach, which draws roughly 10 million visitors annually and anchors the city's $5.9 billion tourism sector, has lost an average of 1.2 metres of dry beach width per decade since 1990, according to data held by the Queensland Department of Environment and Science. That figure has been cited repeatedly in briefings to the state government's South East Queensland Regional Plan working group, which is examining coastal adaptation policy across the region.

The Political Friction

Local LNP councillors have been cautious about language, consistently framing the issue around economic impact rather than climate science. Several have resisted calls from the Greens and independent community groups to declare a formal climate emergency, a step that would trigger mandatory reporting requirements under a proposed state framework. The debate has sharpened in the lead-up to the 2028 council election cycle, with activist groups including Gold Coast Climate Action Network pressing candidates to commit to enforceable sea level targets.

Short-term rental regulation has added another layer of complication. As Airbnb properties proliferate in beachside suburbs from Coolangatta to Main Beach, some planning advocates have argued the concentration of transient accommodation in high-risk coastal zones makes long-term evacuation and adaptation planning significantly harder. The council has yet to formally link its rental regulation work to its coastal hazard framework.

For residents in streets like Goodwin Terrace in Burleigh Heads or along Admiralty Drive in Paradise Waters, the practical question is what all of this means for insurance and resale values. The Insurance Council of Australia flagged in its 2025 annual report that 12,500 properties across the Gold Coast local government area now attract climate-risk loading on their premiums. That number is expected to rise when updated coastal hazard maps are eventually published.

The next scheduled public consultation on the City Plan coastal provisions is expected in October 2026. Council has indicated it will release draft updated hazard overlays for community review at that time, the first comprehensive revision since the original maps were drawn in 2014.
