Off topic - but this is what you remember
It was in Hindmarsh Park Kiama. In those days, coming from Sydney down the coast, you would have been on the Princes Hwy (still would, but the road is better). You would have bypassed Shellharbour completely, and Kiama would have been your coastal stop. We used to go here almost every weekend. Mum would take us to the park, while my father, grandfather and great-grandfather would go fora beer or 10 at the Group 7 Leagues Club across the road.
