Wallabies players have produced a moment of absolute class during the historic first performance of an Indigenous national anthem at an international sporting event involving an Australian team.Olivia Fox, a young singer from the Newtown High School of the Performing Arts, sung Advance Australia Fair in Eora language and then in English before the Wallabies' final Rugby Championship Test of 2020 against Argentina at BankWest Stadium in Sydney.The dual-language anthem has been met with warm approval and calls for it to be introduced permanently — and the reception was even more glowing for Wallabies captain Michael Hooper and his teammates.It was the first time a joint-language anthem has been performed at an international sporting event in Australia.The spectacle was made a truly momentous moment by the entire Wallabies squad singing the Eora language anthem proudly.It was reported this week the playing group had been learning the lyrics in Eora to show the team is serious about recognising the role of First Nations people in the sport.The moving moment left Aussie sport commentators emotional and inspired.Rugby guru Jamie Pandaram posted on Twitter.
