From 1975 to 1978 the open was held at The Australian Golf Club. Kerry Packer had funded a redesign of the course by Jack Nicklaus. The event was broadcast through Packer's Channel Nine network. He also financed a large increase in the prize money. Nicklaus won three of the four events, in 1973, 1974 and 1976 while David Graham won in 1975. The 1979 and 1980 events were sponsored by Dunhill but with less prize money than in 1978. Jack Newton won in 1979 with Greg Norman winning in 1980. The 1981 event was multi-sponsored, without a title sponsor, and was won by Bill Rogers, beating Norman by a stroke.
