I think I'll come too if yall don't mind.
Thought a few good places.
Under Lane Cove Bridge, and beside it, backdrop of nice water.
Graffiti...uummm being into that for a while I think I know a few good places.
Storm water drains, I know where they are - if they are the same ones...takes about an hour or two to look at all the art down there....some good quality.
