Cassowaries in Cape York can be found:
- ‘Far North’ Cape York Peninsula (Lockerbie & McHenry Uplands) – thought to be extinct, no population estimate (data lacking), and
- ‘North’ Cape York Peninsula (McIlwraith Range & Iron Range) – no population estimate (data lacking)
They are found across the landscape from the coastal littoral rainforest and lowland gallery rainforest to the inland highland rainforest. Other habitats such as beaches, mangroves, Melaleuca swamps, and savannah woodlands are also visited and are considered important corridors that link rainforest patches. Their food preference is rainforest fruits.
