Totally of the topic wal, but mystery parents live in Canberra, and they still can't, for the life of them, figure out why all the number plates begin with Y, do you know why? Just so that I can pull my poor old dad out of his misery?
Liz here,
I hope this cures your poor Dad's misery.....
After more than 41 years of issuing numeral only number-plates the ACT introduced an alpha-numeric plate for passenger cars. In 1954 the ACT had been allocated the series YAA-000 to YZZ-999 for this purpose by the Australian Transport Advisory Council. It took until the 20th of September 1968 for the "Y" plates to come into existence. These were the first plates in Australia to use the new reflective sheeting for the background on a permanent basis.
The various states and territories (except Northern Territory, which has all numbers, and Norfolk Island, which has its own NI plates) had plates allocated according to the alphabet.
New South Wales: AAA-000 to FZZ-999
Victoria: GAA-000 to MZZ-999 (Ixx-nnn series skipped)
Queensland: OAA-000 to QZZ-999 (Oxx-nnn series initially skipped by Queensland)
South Australia: RAA-000 to TZZ-999
Northern Territory: UAA-000 to WZZ-999
Tasmania: XAA-000 to XZZ-999
Australian Capital Territory: YAA-000 to ZZZ-999
Commonwealth cars' plates started with a red "Z". By the 1980s the states were running out of new combinations and started using other states' "beginning letter", but ACT stuck with "Y". Various new plates have been introduced which have moved away from the simple 3 letter 3 number setup over the last decade or so.
