What I find really strange is this:
"A blind concession TV Licence costs =A371.25 for colour and =A324.00 for
a black and white TV Licence."
Why? Blind does not necessarily mean 'can't see anything at all'.
At one time we had to have radio (receiving) licences over here. Again
one per house, although I think a car radio needed a separate licence
(!). Registerd blind people got a free radio licence. When the radio
licence was abolished, they got a discount on a TV licence of the same
amount as the final cost of the radio license (I think it was either
\pounds 1.25 or \pounds 1.50 in decimal currency, but I might be wrong).
This discount stayed the same for many years, even though the TV
licence went up several times.
