The Crown of Thorns Starfish (COTS) is a natural predator of coral on the Great Barrier Reef and is thought to have been present in low numbers for thousands of years. As a result of human induced influxes such as nutrient loading and fishing pressure COTS "blooms" have become a threat to coral health.

The Association of Marine Park Tourism Operators (AMPTO) have run a COTS management program on reefs of key tourism and/or conservation value for over two decades. The program has demonstrated that COTS control is a useful tool for localised COTS management.

A side benefit of the COTS program has been the creation of training and employment opportunities for youths in the Wet Tropics Region, with participants enjoying an 85% employment rate on completion of the program.
