The barber shop at Riverwood (Sydney suburb) always had about 4 machines. My first memory was playing Gottliebs from 1967. Roselands shopping centre had a huge Grace Brothers store which had a large pet department upstairs in the early 70s. Outside the pet store was a kids courtyard play area which had about 8 machines. I remember playing mainly Williams EMs there. Gulfstream, Superstar, Rancho come to mind.
