Cairns’ $5 Million Starfish Control Initiative Spurs 61 Jobs and $20 Million Economic Boost

New economic modelling from James Cook University shows that a $5 million program aimed at curbing crown‑of‑thorns starfish (CoTS) in the Cairns region has generated 61 new jobs and sparked roughly $20 million in economic activity, a win for both local livelihoods and reef health.

CoTS are predatory marine invertebrates whose population explosions can decimate coral reefs, stripping away the habitat that underpins tourism, fisheries and coastal protection. The Great Barrier Reef, of which the Cairns sector is a key part, has long struggled with periodic outbreaks that threaten its biodiversity and the economies that depend on it.

The recent control effort allocated the $5 million to a suite of interventions, including targeted removal of starfish, monitoring of outbreak hotspots, and training of field teams. While the funding source was not detailed in the original release, the program represents a focused investment in reef management rather than a broader, untargeted expenditure.

James Cook University researchers applied an input‑output economic model to trace the flow of spending through the regional economy. Their analysis linked direct costs of the control operation to indirect benefits such as increased demand for marine‑science services, support for local suppliers, and the preservation of tourism revenue that would otherwise decline under unchecked starfish damage. The resulting 61 jobs span field technicians, data analysts and support staff, while the $20 million figure captures both immediate and ripple‑effect contributions.

Experts say the findings underscore how environmental interventions can deliver measurable economic returns, reinforcing the case for continued or expanded funding. As reef managers contemplate scaling similar programs across other vulnerable sections of the Great Barrier Reef, the Cairns model provides a data‑driven template that aligns ecological stewardship with community prosperity. The next steps will likely involve monitoring the long‑term health of the coral, assessing whether job creation sustains beyond the project’s lifespan, and evaluating how the approach can be integrated into broader reef‑resilience strategies.
