Yes, you could have a yellow plate issued in the early 1950s and still have it today as you bought new vehicles. When the yellow plates were issued they put the frighteners on owners with the superseded B&W plates. My father had AL ... and it was replaced with ADL... There was a huge outcry and the Department of Motor Transport were smashed into submission, supported by a fantastic gentleman and former politician Sir Frederick Stewart who had B&W number plate NSW 1. Even this no plate gets a mention here:
Biography - Sir Frederick Harold Stewart - Australian Dictionary of Biography
Stewart House the children's respite care hospital was funded by him.
In 1969 I had AWT... issued for a Land Rover, but it was a re-issue. Sometime in the late 1970s a friend drove his Series 3 SWB into Dad's factory and Dad said "that is the b. no plate I handed in AL..." That was my friend's initials. Dad told us the story and thought it good that Tony got the number when they started letting people have available "personalised" number plates. It really meant nothing to Dad - I think it came with his Mercury Ute.
Originally BZZ would have been issued in late 1959.
