Nice shot. But I can't see myself in the crowd......
I used to catch a route 24 trolleybus to school from under the Waltons neon sign. But the shot is post-1963. The 8 "Phoenix" trams [547 - 554] were built "out of the ashes" of the Paddington depot fire, in about 1963. The "Yellow" taxi [in fact, orange] is an HR Holden - therefore, the photo is post 1966.
The Brisbane system [always immaculately maintained] would close in about three years, in 1968 - 1969, and is still missed.
