Melbourne is a very popular tourist destination. As the capital of its state, Victoria, it is an important city, and it has now twice been voted top in a list of the world's best cities to live in.
A major attraction of Melbourne is culture - the city is famous for arts, theatre and music. People often go for music festivals or other events, or spend time in the popular Fitzroy district with its Bohemian mix of artists, bookshops, quirky cafes and vibrant night life. It's also a good place to explore Australian history, from the Aboriginal inhabitants through the impact of early settlers to the present - many museums and events explore all these.
It's also a great place for fine dining, thanks to the mix of cultures that have moved to the city over the years. You can find every type of cuisine as well as examples of 'fusion food' where different cooking traditions have combined to create unique dishes.
Plus, it's a beautiful place with some fascinating buildings, and the countryside and wildlife should be visited too. There really is lots to do - you can get some more ideas here.
