The Pan Pacific Cup returned to Brisbane in 2016, again hosted by the UniDive Gauls at the Brisbane Aquatic Centre in the Sleeman Sports Complex, a venue for the 2018 Gold Coast Commonwealth Games. The tournament again saw the F.A.T Singapore team return to challenge the eight Australian teams.
Pan Pacific Cup 2016 was the first tournament for the newly-formed Perth Raiders, consisting of extremely talented players with roots in national-level underwater hockey. They surprised the established UWR clubs by overcoming some of the country's strongest teams, to meet the reigning champions, the Sydney Whales, in the grand final, where they kept the Whales scoreless. It was only until the penalty shootout at the conclusion of the match where the Whales finally prevailed to win their second Pan Pacific Cup.
