Sunbury Pop Festival was an annual Australian rock music festival that was the seventh of more than a dozen major outdoor rock festivals staged in Australia between 1970 and 1975, but it was the only one that became a continuing event, at least for four years. It was promoted by Odessa Promotions, which was formed by a group of television professionals headed by John Fowler from GTV9 in Melbourne. Festival publicist Jim McKay recalled, "It was a good idea over coffee at the Channel Nine canteen... We were a bit bored, wondering what to do next... Why don't we do a pop festival, like Woodstock?" From late 1971, Odessa Promotions touted the forthcoming festival as "41 hours of non-stop entertainment. Sunbury, the rock happening of 1972. Three days of sun-filled togetherness".
