Fiji is preparing to introduce Australian-made maritime surveillance drones to strengthen monitoring of its extensive ocean territory.

The Bluebottle vessels can operate at sea for months, using solar and wind energy to support long-distance patrols. Their sensors and satellite communications allow operators to identify vessels that may require further investigation.

The technology forms part of Australia's wider Pacific maritime security support, with Fiji expected to receive its first drones in 2027.

But new reporting from ABC Pacific on 2 November highlights an important concern: organised crime networks may respond by changing their routes or adopting similar technology.

University of Canterbury Pacific security specialist Associate Professor Jose Sousa-Santos warned that criminal groups could adapt quickly.

For Fiji, the challenge is considerable. Its maritime territory spans vast distances, while authorities have limited patrol vessels and personnel.

The drones could help direct those resources towards suspicious activity instead of requiring continuous crewed patrols across large areas.

Yet detection alone does not guarantee an interception. Authorities still need vessels, personnel and cooperation between agencies to respond.

The development raises a question for Pacific governments: will improved surveillance shift the balance against traffickers, or simply force criminal networks to find different routes?
