Archerfield in 1947 had had its wartime blast walls removed from the glass front of the terminal by 1947 but still had its camouflage paint scheme, see here:

Also, in 1947/48 the airlines were all moving to Eagle Farm to the infamous igloo hangars and longer runways. I have never seen any photo of Archerfield Terminal Building with a white fence out the front, intruding so far onto the tarmac.
