Papua New Guinea

Explanation:

The island of New Guinea (divided between Papua New Guinea and Indonesia) is one of the largest islands in the world. It is located just north of the northeastern part of Australia, and on the southeast of Southeast Asia. It is a very curios island, where there's beautiful nature and all sorts of land forms and geographical features. The island has both lowlands that have relatively fertile soil, and they can be used for agriculture, especially for the production of tropical plants, but it also has a glacier. The glacier kind of seems out of place, as the island is relatively close to the Equator, and the majority of it is covered with dense tropical rainforests. It has to be taken in consideration though that this island's central part actually is consisted of very high mountains, with lot of peaks going well over 4,500 meters, and the glacier is located on over 4,800 meters of elevation.
