This set me thinking, where next? Other states have various combinations.
So, in an idle moment, I turned to Wikipedia (where else?) It's stated there that -
"Soon Victoria will have exhausted all ABC-123 format plates. Two main combinations are under consideration: A12-AAA or V123-ABC (like South Australia's "S" prefix) New colour schemes for the future general series may be the existing blue on white, or black characters on fluorescent orange."
Good grief.... fluorescent orange number plates? Hopefully good sense will prevail and we'll be spared that! (Or is it just a joke on Wikipedia...???)
