From 1994 to 2019 the Tuvalu policed its 200-kilometre exclusive economic zone with the Pacific-class patrol boat HMTSS ''Te Mataili'', provided by Australia.  Australia gave Tuvalu and 11 other partners in the Pacific Forum, for use in maritime surveillance and fishery patrol and for search-and-rescue missions. ("HMTSS" stands for ''His/Her Majesty's Tuvaluan State Ship'' or for ''His/Her Majesty's Tuvalu Surveillance Ship''.) On 7 April 2019, Australia donated a Guardian-class patrol boat that was named HMTSS ''Te Mataili II'', and which will be operated by the maritime surveillance unit of the Tuvalu Police Force.
