Coon Island in Lake Macquarie has been in the news lately, with calls for its name to be changed given the overt derogatory nature of the current name. I wholeheartedly agree that changing the name is the right thing to do.
I had to look up where the island is located, which is at the northern point of land above Swansea.
I found an old Regional Charting Map in the Historical Land Records Viewer that shows the island.
