Several weeks ago, Julie of
Sydney Eye and I spent a pleasant few hours visiting
Garden Island, the home port for major naval fleet units based on the East Coast of Australia. One end of the island (fenced off from the base) is open to the public and houses a museum, cafe and various other bits and pieces, set amongst beautiful garden areas.
This is the small Rivercat type ferry that travels to and from the Island, only a few minutes from Circular Quay.
