Sunbury 1972 Rock Festival was held over the Australia Day long weekend in January 1972. Traditionally, the Sunbury rock festivals were always held over this period.
The 1972 Sunbury Rock Festival was the first of four Sunbury Rock Festivals. The subsequent events were held in 1973, 1974 and 1975.
All the performers at Sunbury '72 have been known to be Australian acts though some of the performers apparently had originally come from overseas.
The Sunbury 1972 Rock Festival is notable for the debut performance of Billy Thorpe & the Aztec's song "Most People I Know Thnik That I'm Crazy".
