I use Ceva to transport my race car around Oz. They're quite trustworthy and slightly more capable of handling sporty cars it seems.
When you get them to Qld, you need a mechanic to inspect and give you a "raodworthy certificate", which you then take, along with the vehicle, to Qld Transport dept (offices everywhere), pays your money, have them confirm the numbers, and issue you with plates. They then post a label.
