Samoa nema redovnu vojsku jer je za pitanje obrane zadužen Novi Zeland. Postoji samo jedinstvena policija, Samoanska policijska služba. Australija će izgraditi novi kompleks policijske uprave u glavnom gradu Samoe Apia. Samoanska policija je dobila i patrolni brod, klase Pacifik za patroliranje teritorijalnim vodama. Partnerstvo Samoe i Australije u jačanju policijskih snaga je dio Pacifičkog policijskog razvojnog programa, koji je opet sastavni dio inicijative australijske vlade o bilateralnoj i multilateralnoj suradnji policijskih snaga u pacifičkoj regiji. Samoa je učestvovala i u misiji Ujedinjenih naroda na Istočnom Timoru, kao i u policijskoj Misiji regionalne pomoći na Salamonskim otocima od 2003. godine.

      Samoa has no standing army, as defense is the responsibility of New Zealand. However, Samoa does have a unitary national police force, the Samoa Police Service. Australia will build a new police headquarters in the Samoan capital Apia, as part of a major initiative to strengthen the Samoa Police Service.  The SPS operates the Pacific-class patrol boat Nafanua provided by the Australian Government as part of the Pacific Patrol Boat Program.The Samoa Australia Police Partnership is a component of the Pacific Police Development Program, which is a Government of Australia initiative supporting a broad range of bilateral and multi country police capacity development initiatives throughout the Pacific region. Samoa has provided police officers to the Regional Assistance Mission to Salamon Islands since July 2003. Samoa's police force also served in East Timor as part of a United Nations peacekeeping effort to maintain peace and security in the region in 2001.
