I have had NSW personalised plates (3 letters, 2 numbers, 1 number) on my cars for 25+ years, no yearly fee, or exorbitant issue prices back then.
Also discovered about the same time that NSW 3 letter 3 numbers started the numbers at 050, so personalised plates could get the low numbers.
Number plate for missus fixed, same no fees, only standard issue price.
Saves old people the inconvenience to trying to remember what the current plate is
Personalised plates have now become a money making rort for NSW Gov.
