Sydney Harbour Bridge was built in 1932 so this dish postdates that.
With this sort of view ware, often the blanks were imported and the photos glued on locally.
The only group in Australia making domestic pressed glass items in 1932 (and until after the war sometime) was The Crown Crystal Glass Company. However, I don't recognise the pattern and the colour doesn't look right (although that can be an artifact of digital photography and computer settings). I suspect that this one was probably imported. :?
Does anyone know about ferries? The boat in the lower left hand side might narrow down about when it was made.
I'm not sure whether that information helps or not!
