Captain Slack and the convicts.
I was told In 1976 ,by a very elderly timber cutter that worked on Tamborine mountain, that Slacks Creek, was named after a very nasty commander named Slack. He said that It was told that Captain Slack wanted to explore the creek and subsequently see if he could reach the river. He commanded a few convicts to assist him on his exploration.The convicts came back but Captain Slack was apparently taken by a crocodile.No one asked how he came to be in the river and not in the boat. From then on many of the convicts became free settlers and the Albert Shire was created.
