Yes, I remember the Manly Fun Pier. My parents used to take me there during the 1960's. Sometimes it was the only amusement park open as Luna Park used to close down for maintenance during the winter months back then. The rides that I can recall at the Manly Fun Pier were the Dodgems, ferris wheel, merry-go-round/carousel, ghost train, upside down house, Rock-o-plane, Octopus, what I used to call Dodgem boats, mirror maze. I think there was a shooting gallery and maybe a Penny Arcade.
During the Ghost Train ride, the car would crash through doors and you thought you were going to end up in the harbour but a couple of sharp turns and you would be back inside.
When did it close down? Apart from the merry-go-round (Kales Carousel) which is now set up at Darling Harbour, I wonder what happened to all the rides? Scrapped I suppose.
Thanks for posting those postcard pics of the Fun Pier.
