What is a major landmark in Tasmania?

Cradle Mountain is a major landmark in Tasmania, renowned for its stunning natural beauty and significance within the Tasmanian Wilderness World Heritage Area. The mountain is part of the Cradle Mountain-Lake St Clair National Park, which is famous for its breathtaking landscapes that include rugged peaks, dense rainforests, and picturesque glacial lakes. Cradle Mountain is also popular for hiking and outdoor activities, attracting many tourists who want to experience its unique flora and fauna.

The other choices do not pertain to Tasmania: the Blue Mountains are located in New South Wales, Uluru is a significant monolith and cultural landmark in the Northern Territory, and Bondi Beach is one of Sydney's most famous beaches, also situated in New South Wales. Therefore, these alternatives do not represent major landmarks in Tasmania, making Cradle Mountain the correct choice for this question.
