"Aussie Aussie Aussie, Oi Oi Oi" is a cheer or chant often performed at Australian sport events. It is a variation of the Oggy Oggy Oggy chant used by both soccer and rugby union fans in Great Britain from the 1960s onwards. It is usually performed by a crowd uniting to support a sports team or athlete. The alternate is for an individual to chant the line "Aussie, Aussie, Aussie!" and the crowd to respond with "Oi! Oi! Oi!".
