As the van is registered with Queensland licence plates, we now need to go through the relatively easy process of registering the van in Western Australia. We popped into the licencing centre in Mandurah a few weeks ago for some advice - they were actually extremely helpful. In short the van will need an examination before it can be registered in WA. As the van currently isn't allowed to be towed on WA roads (due to QLD plates) we will need to obtain a 'Temporary Moving Permit' and take the van into the Mandurah inspection/examination centre. If all is okay, it's registered in our names and WA plates are issued. At the same time the QLD plates are handed in and they will give us a plate receipt. We then post the plate receipt to the QLD Dept of Transport and job done. Sounds easy (hopefully!)
Each states licencing requirements are very different but the relevant states Transport Dept websites have been very informative and helpful.
