I decided to make my post mostly about industrial structures and I chose buildings and objects from two ports. Sydney Harbour and Port Adelaide. The Sydney ones were taken at Cockatoo Island when I visited there. I thought that it was very interesting to see the remains of the naval dockyard that had once been there as much as the historic convict era buildings. Fort Denison the small island in the harbour is also convict era. The other Sydney photo is a building on a wharf I think at Rose Bay where they do charter flights with a sea plane.
Port Adelaide is a place that had a strong industrial background which is now being replaced by townhouses and flats which are not improving the landscape.
I enjoyed using Adobe Photo Elements to edit these old photos.
