Good evening,
That postcard did the trick Chris, that style of building is common around Bohemia rd/London rd. Bohemia Place was a part of Bohemia rd, may still be, the large place in the background is 61 Bohemia rd, on the corner of Upper South rd. The PO is now Frydays fish & chip shop or maybe the first part of Vantage Pharmacy. I didnt count the no of shops to the corner.
You can see it on Google maps st view.
