The island of Tasmania is over 68,000km2 and is larger than Sri Lanka. It is not part of the Australian mainland but is part of Australia. Australia should therefore be included in your list.

Incorrect. According to Wikipedia, Sri Lanka is 65,268 km², while Tasmania is only 65,022 km², so Australia shouldn't be on here.

Thank you for the correction. I only checked the area of the state which includes many other islands. Good to know.

68,000km² is the area of the entire state, not just the main island.

The largest island the US has is the island of Hawai'i ("The big island") at 10,433km², way smaller than the last country on this list.
