You should definitely consider it. Those standard plates we have in Australia just aren't classy enough.
I had a quick look on the QLD plate site, and noticed it was pretty different from ours. By memory, I payed about $550 for Acrylic slimline plates where you can choose any number/character combination you'd like (although there is hardly anything good left) and a few colours to choose from. My Celica had Aluminium black slimline plates for $150, where you could choose two letters, two numbers, and the final two letters had to be 'WA'. But again, there was hardly anything left to choose from.
The one you mentioned doesn't sound too bad. It's a shame the options in QLD are a bit restricted to a higher price range though. Still, I reckon it would look awesome in black or dark blue.
