Yep, that's the "Old" Victoria Bridge. I remember it well - the 1969 version that is

There are still remains of an even earlier bridge as a memorial.
I travelled a lot with my kids on those trams. The kids loved the really loud clackity clacky as both the trams and the bridge shook. The skyscraper (do they still call them that?) in the background was the first in Brisbane - Torbeck appartments which have recently been renovated for reaching an historical milestone.
I don't know about the barricades ( without Googling) where the people are standing. But there seemed to be always road repairs in Brisbane which became a butt of jokes for George Wallace jnr, an old vaudevillian, by then appearing on TV. It was also a time when old buildings were being pulled down. Trittons, the furniture shop, had their big shop near that corner. My uncle in law worked there in the early 1900s.
That's enough from Gazania
