Cairns’ $5 Million Starfish Control Program Generates 61 Jobs and $20 Million Economic Impact

A recent economic analysis conducted by James Cook University indicates that a $5 million initiative to suppress crown‑of‑thorns starfish (CoTS) in the Cairns area has produced 61 additional positions and triggered about $20 million in economic activity, benefiting both local livelihoods and reef health.

Crown‑of‑thorns starfish are predatory marine invertebrates whose sudden population surges can ravage coral reefs, removing the habitat that supports tourism, fisheries and shoreline protection. The Great Barrier Reef, with Cairns as a pivotal region, has repeatedly faced such outbreaks that endanger its biodiversity and the economies that rely on it.

The latest control campaign devoted the $5 million to a range of actions, such as targeted starfish removal, surveillance of outbreak hotspots, and the training of field crews. Although the original announcement did not specify the funding source, the effort constitutes a directed investment in reef management rather than a generic, untargeted spend.

Researchers from James Cook University employed an input‑output economic model to map how the expenditure circulates through the regional economy. Their study connected the direct outlays of the control work to indirect gains like heightened demand for marine‑science services, support for local suppliers, and the preservation of tourism revenue that would otherwise fall if starfish damage went unchecked. The 61 jobs created include field technicians, data analysts and support personnel, while the $20 million estimate captures both immediate and secondary contributions.

Specialists note that the results highlight the capacity of environmental actions to generate tangible economic benefits, bolstering arguments for sustained or expanded financing. As reef managers consider replicating similar initiatives across other vulnerable sections of the Great Barrier Reef, the Cairns example offers a data‑backed framework that couples ecological stewardship with community prosperity. Future steps will likely involve tracking the coral’s long‑term condition, determining whether the employment gains persist beyond the project's duration, and exploring how the approach can be woven into broader reef‑resilience plans.
