Cairns Council Approves Major Waterfront Rezoning as Housing Pressure Mounts

Cairns City Council has greenlit a significant rezoning proposal for the Portsmith precinct on Monday, paving the way for mixed-use development across 12 hectares of currently underutilised industrial land. The move marks the most substantial planning shift in the city's northern growth corridor since the Cairns 2050 strategy was adopted in 2023.

The development envelope, stretching from the Barron River towards Pease Street, is expected to yield approximately 800 new residential units once construction commences in early 2027. Council planners indicated that the proposal aligns with demographic projections showing Cairns' population could reach 200,000 by 2035, up from the current 160,000.

"This is about unlocking underperforming land while maintaining the character of our established suburbs," a council spokesperson said during the planning committee session. The rezoning permits buildings up to 15 storeys in the core precinct, with height restrictions tapering towards neighbouring residential areas like Mooroobool and Edge Hill.

However, the decision arrives amid mounting housing affordability challenges in Cairns. Median house prices in established suburbs have climbed 22 percent over the past 18 months, according to local real estate data, while rental vacancy rates sit at just 1.2 percent. The median rent for a three-bedroom home has reached $420 per week, placing pressure on working families across the city.

Community groups including the Cairns Renters Collective have raised concerns about whether the new supply will address affordability or simply attract investor purchases. "We need genuine commitments from developers to include affordable housing stock," advocates stated in a submission to council.

The Portsmith rezoning does include a 15 percent inclusionary housing requirement, though the mandate applies only to developments exceeding 50 units. Developers can alternatively contribute to an affordable housing fund, a mechanism that has generated limited contributions in previous Cairns projects.

Separately, council fast-tracked approval of a master plan for the stalled Marlin Coast estate development south of the airport, unlocking 240 additional lots for residential construction. Planning delays on that 280-hectare site had contributed to supply constraints pushing prices higher across the wider region.

The Cairns and District Property Council welcomed the announcements, describing them as essential to moderating price growth. "Supply is the foundation of affordability," the council noted in a statement released Thursday.

Public exhibition of detailed design plans for Portsmith is scheduled to commence August 15, with final approval anticipated by year's end.
