Australia and Sri Lanka have launched the third phase of Operation Disi Rela, a joint maritime security initiative aimed at combating maritime crime and enhancing security across regional waters.

The operation officially commenced on Monday in Colombo and will continue until June 17, covering several locations across Sri Lanka, including Colombo, Trincomalee, Valaichchenai, Batticaloa and Mirissa.

According to the Ministry of Defence, Disi Rela—which means “keeping a watchful eye over the maritime environment”—demonstrates the continued commitment of both nations to preventing illegal maritime activities and builds on the success of previous operations.

As part of its support for Sri Lanka’s coastal and maritime security efforts, the Australian Government donated five high-performance All-Terrain Vehicles (ATVs) and 12 long-range drones to the Sri Lanka Coast Guard. The equipment is expected to enhance the Coast Guard’s operational capacity to detect, respond to and combat illicit activities along Sri Lanka’s coastline and surrounding waters.

The initiative also focuses on strengthening joint operational capabilities, improving intelligence-sharing among law enforcement agencies and fostering closer engagement with coastal communities. These efforts are intended to counter transnational maritime crimes such as human trafficking, drug smuggling and illegal fishing, while contributing to greater regional maritime security and stability, the Defence added.

The opening ceremony was attended by Australian High Commissioner to Sri Lanka Matthew Duckworth, Australian Defence Adviser to Sri Lanka Colonel Amanda Johnston, and officials from the Australian High Commission. Representing the Sri Lanka Coast Guard were Deputy Director General Commodore Prasad Jayasinghe, department heads and several senior officers from the Tri-Forces.
