Myponga Pop Festival

The Myponga Pop Festival was a music festival which took place on a farm near Myponga, South Australia from 30 January to 1 February 1971. Its promoters were Alex Innocenti, Trevor Brien and Music Power's Hamish Henry. The festival was headlined by heavy metal pioneers, Black Sabbath. Cat Stevens was advertised as co-headline artist at the festival but he cancelled to perform in Los Angeles. The compere was Adrian Rawlins, who wrote of his experiences at Myponga, and other festivals, in his book Festivals in Australia: an Intimate History (1982). Another international act was Syrius, (from Hungary, see Jackie Orszaczky).

The Canberra Times' correspondent reported that the "festival rocked to a close tonight after taking l​1⁄2 days to warm up. The pop crowd, estimated at 8,000, started arriving at the 62-acre farm at Myponga early on Saturday morning. Most of them had brought plenty of alcohol and, although violence did not erupt, the atmosphere at the festival was tense at times." The promoters did not make any profit.

In March 2013 Black Sabbath's Ozzy Osbourne recalled the group's debut Australian performance, "That was the Myponga Pop Festival if I remember right? Management told us we'd have an exact copy of our amplifiers there, which we thought was great, but when we got there they were nothing like our amplifiers! But you know what? You get up there and do your best and I had a good time. I remember we had a big party at the hotel and some chicks there got absolutely shit-faced and were throwing up everywhere and we had to send them home. I don't remember much on the sex front after that..."
