What is the largest island in the Australian continent?

Tasmania is indeed the largest island in the Australian continent. It is situated to the south of the mainland of Australia and is often considered a part of the continent itself due to its geographical and political ties. Tasmania has a total area of about 68,401 square kilometers, making it the most substantial island that is fully considered part of Australia.

The island has a rich cultural history and diverse ecosystems, featuring everything from rugged mountains to pristine beaches. Tasmania also boasts a variety of unique wildlife and is known for its natural beauty, which contributes to its significance as a notable part of Australia.

The other regions listed, such as Victoria, New South Wales, and Queensland, are all states on the mainland of Australia, not islands. While they are important areas within Australia, they do not qualify as islands in the context of the question, making Tasmania the correct choice.
