On Australia Day, 26 January 2017, at the "Australia Day Concert: Live at The Sydney Opera House", Arena joined a collection of Australia's best talent, including Guy Sebastian, Human Nature, Dami Im, children's group The Wiggles, and others, performing contemporary tunes and tributes to the great songs of Australia's past. The 2017 Australia Day Concert was a free public event, organised by the NSW Government through its tourism and major events agency. Arena, as one of Australia's most accomplished performers, with a career spanning several decades, said prior to the event, "Australia Day is a great opportunity to come out, eat some delicious food, listen to some amazing music and take part in the diversity that defines our country" and "I can't wait to be part of the day – to stand in the middle of the harbour, to sing with the harbour crowds and school choir, and give my own version of a salute to Australia".
