Main Body
On 19 August 2026, the Department of Defence said the Australian Defence Force had supported Operation Island Chief, a Pacific-led maritime security operation in Solomon Islands focused on fisheries surveillance. The department said ADF aerial surveillance helped monitor 320,000 sq km of ocean and identify 19 vessels as part of an effort to deter illegal fishing and transnational crime.
The Department of Defence said the activity involved Pacific nations and partners, with Australia contributing surveillance support to the operation. That arrangement mattered operationally because, according to the department, the mission was Pacific-led and used shared monitoring to strengthen regional maritime security around Solomon Islands.
The operation followed Australia’s 17 August 2026 opening of the Western Border Outpost in the Shortland Islands, as GPS previously reported. On that date, the Minister for Defence said Australia and Solomon Islands had delivered the facility to improve border management and maritime security by bringing relevant agencies into one site, with more than A$100 million invested, 368 jobs created and more than 1,000 local contracts awarded.
Together, the surveillance operation and border facility showed Australia’s practical security support for Solomon Islands through both mobile monitoring and fixed infrastructure, according to the Department of Defence and the Minister for Defence. The Department of Defence linked the operation to illegal fishing and transnational crime, and the Minister for Defence linked the outpost to border management, making the activity relevant to Pacific resource protection, law enforcement coordination and regional stability.
