The Royal Solomon Islands Police Force (RSIPF) and the Australian Federal Police (AFP) have signed a memorandum of understanding to work more closely together.
The deal includes: Information sharing in all areas of law enforcement, co-ordinated operations across all transnational crime types, strengthening and consolidating existing networks and assistance in capacity building and professional development.
A deputy commissioner for the AFP, Leanne Close, said it would enhance relationships at the working and executive levels for both agencies.
Priority issues included drug offences, people trafficking, transnational sex offences, firearms trafficking, cybercrime and terrorism, she said.
The AFP has been the RSIPF's main partner since responding to the Solomon's ethnic conflict in 2003.
With police forces from across the Pacific, it contributed to the Regional Assitance Mission to Solomon Islands (RAMSI) until the mission ended in 2017.
