(CNN)National rugby players sang an Indigenous version of Australia's national anthem for the first time on Saturday, a move that won widespread praise and spurred calls to make it a permanent feature at Australian sporting events.

Performing arts student Olivia Fox sang a powerful rendition of the national anthem, first in the language of the Eora Nation -- a group of Indigenous clans from the Sydney metropolitan area -- and then in English, before Australia's' Tri-Nations test against Argentina at Western Sydney Stadium.
