The highest mountains of Oceania are found in its largest island, New Guinea, with the highest peaks in Indonesian territory, a nation that is mostly located in Asia; however, even in Papua New Guinea they exceed 4,500 meters in height.The only other island with an elevation above 4,000 meters is the largest of the Hawaiian archipelago, thanks to two of the largest shield volcanoes on our planet; follows the South Island in New Zealand.
The oceanic continental part, corresponding to Australia, does not reach prominent heights, given that the highest peaks do not exceed much the two thousand meters.
