Free tickets for this event (max 5), don't know what else to say so just going to copy paste the description from the website:
Enjoy live performances by Australian music legends Birds of Tokyo, Tutti and the Australian Girls' Choir, plus a 15 piece orchestra fusing global sounds and cultures that celebrate the story of us
Connect with the world’s oldest living culture through a mesmerising ceremonial opening, and join us as we honour our front line and emergency workers, together with a spectacular stylised intercultural Parade.
Australia Day is for all Australians, no matter where our personal stories begin. We embrace the Australian spirit and our sense of community. We find optimism and hope as we look to the future in a time of unprecedented challenge and change.
Aus Day in the Arena and the Australia Day 2021 program is assisted by the Australian Government, through the National Australia Day Council with support from the Government of South Australia, Department of the Premier and Cabinet.
