I suppose we do have some leeway in Qld, in that a slimline personalised plate is available.
Normal size is 375 mm X 134 mm, with the slimline version being the same width but only 100 mm high. A small concession, but it all helps!
The personalised plates are available in just about any colour combination you can imagine with a variety of backgrounds too.
