Because it is a significant landmark. Australia is known internationally by the Sydney Harbour Bridge
The Sydney Opera House isn't owned by anyone individually. It also cannot be sold, traded, or bought because it is one of the World Heritage Sites and also because it is a very important icon of Australia.
The Sydney Opera House is situated on Bennelong Point in Sydney Harbour, Australia. It is positioned near the city center and is flanked by the waters of Sydney Cove, providing stunning views of the harbor and the Sydney Harbour Bridge. This iconic architectural masterpiece is a UNESCO World Heritage Site and a symbol of Australia.
Natural sites would be the Great Barrier Reef. Cultural world heritage sites would be places connected to people such as the Sydney Opera House.https://simple.wikipedia.org/wiki/List_of_World_Heritage_Sites_in_Australia
