Today during Melbourne Open House I visited the former High Court Building in search of some Art Deco.
The court building was originally designed by John Smith Murdoch and completed in 1928. A second storey was added in 1935 by H J MacKennal and it is here that I found some fixtures very much to my taste.
The vent shown on the left is one of eight, four each on two octagonal light wells breaking through the upper floor.
