Nafanua II (04) is a Guardian-class patrol boat being built in Australia for Samoa. It will replace the original Nafanua, supplied to Samoa three decades earlier. Her crew will be drawn from the Samoan Police Force.
Australia supplied 22 Pacific Forum-class patrol boats to 12 of its smaller Pacific Forum allies when the United Nations Convention on the Law of the Sea established that maritime nations controlled an economic exclusion zone 200 kilometres (120 mi) off their coasts.
Manufacturer Austal handed Nafanua II over to Samoan representatives at its plant in Henderson, Western Australia, on August 16, 2019. Present at the handover ceremony, representing Samoa, were Fiame Naomi Mata’afa, and Fuivaili’ili Egon Keil, Samoa's Deputy Prime Minister and Commissioner of Police. Representing Australia were Linda Reynolds and Melissa Price, Minister for Defence and Minister for Defence Industry.
Samoa agreed that Nafanua II would cooperate under the Niue Treaty Subsidiary Agreement to conduct fishery surveillance as it transitted Australian waters, on its first voyage to Samoa, even though she had yet to be officially commissioned.
Nafanua II arrived in Apia on October 4, 2019.
