After watching the video of "22 Australia Incentive Travel Promo", please answer what is the theme of the promotion?

The promotional film was created by Tourism Australia in collaboration with BazLuhrmann, an internationally renowned filmmaker, director and writer. It aims to show the profound essence of Australia's tourism culture to the global audience, encourage tourists to go to Australia to set their minds free and regain themselves, and further consolidate and enhance Australia's image as the first destination in the hearts of world travelers.

CommonwealthofAustralia (English: Australia for short), with a territory of 7.692 million square kilometers, is located between the South Pacific Ocean and the Indian Ocean, surrounded by the sea. It is the only country in the world whose territory covers a whole continent, so it is also called "Australia". Australia, with many unique animals, plants and natural landscapes, is a multicultural immigrant country.
