Which peninsula forms the northeastern tip of Australia?

Cape York Peninsula forms the northeastern tip of Australia.

The peninsula extends northward from Queensland between the Gulf of Carpentaria on the west and the Coral Sea on the east. Its northernmost point is Cape York, which lies near the Torres Strait separating mainland Australia from New Guinea. The region covers about 137,000 square kilometres and is sparsely populated.

Cape York Peninsula contains tropical savannas, rainforests, wetlands and extensive river systems. Much of its natural environment remains relatively undeveloped, and the peninsula is known for difficult roads, seasonal flooding and long distances between settlements. Indigenous Australian communities have lived in the region for thousands of years.

It is different from the Yorke Peninsula and Eyre Peninsula, both in South Australia. The word “York” appears in all three names, but Cape York Peninsula is the one at Australia's northeastern extremity.
