Olivia performed at the VFL Grand Final at the Melbourne Cricket Ground in 1986. This is an Australian football which differs from both soccer and American football.
The video features a very short message from Olivia and small footage from the rehearsals. She sang Waltzing Matilda and Advance Australia Fair, Australia's national anthem, in full Koala Blue gear. Some fans obviously came to see her, as she hadn't performed in a couple of years at this point.
