Hell no, the R&I tower was built around 85/6. There is no landscaping near the Ent Cent so it could be early as 75 I reckon. Not sure what that building under construction is though. Oh the R&I tower was originally the BOND tower.

eta: that's a great pic btw, so many things I remember in it.
The old carriage sheds at Perth station, freight cars still being there, the Boans buikding and the old Forrest place before it was turned into what we have now.
