I live in Australia. The difference may be the electrical certification number.
There is a slight difference between UK PAL and Australian PAL. Australia is PAL B. Digital TV is the same as Europe.
I would advise you to login into the Australian Whirlpool Forums: http://forums.whirlpool.net.au/
It is a big forum; you will have to try and navigate your way through to the correct section.
Also consult:
The Australian Communications and Media Authority:

In Australia we don’t pay TV licences; it is paid for from your income tax.
