title: Giant trevally
context: The giant trevally is abundant in the central Indo-Pacific region, found throughout all the archipelagos and offshore islands including Indonesia, Philippines and Solomon Islands. Along continental Asia, the species has been recorded from Malaysia to Vietnam, but not China.[5] Despite this, its offshore range does extend north to Hong Kong, Taiwan and southern Japan.[11][14]  In the south, the species reaches as far south as New South Wales in Australia[20] and even to the northern tip of New Zealand in the southern Pacific. Its distribution continues throughout the western Pacific, including Tonga, Western Samoa and Polynesia, with its westernmost limits known to be the Pitcairn and Hawaiian Islands.[10][15]
