I came across this old playground rocket whilst doing "The Moorabbin Rocket" geocache - and I seem to have childhood memories playing on this or a similar rocket many years ago, but can't confirm this.

"...a local entrepreneur Sid James bought the rocket and installed it at his amusement park on the Nepean Highway. It sat there for many years until the park closed and the dilapidated rocket once again ended up in a scrap metal dealer's yard in Chesterville Road." (Take The Moorabbin Rocket cache story with a large pinch of salt!...)
