How to transfer new Qld caravan to S.A.

Not sure of the answer to your predicament....
How can it be registered,in Qld, in your name, unless to a Qld address..?

I have not been down that track before with respect to the S.A. rego system. However I do know that all states have reciprocal arrangements in place regarding the transfer of rego for all vehicles. I don't know why someone from S.A. transport
would tell you not to register it in QLand and get it to S.A. asap for a rego check.
What happens if you need to be away from S.A. for more than the three weeks you intend to be. I suspect that the S.A. transport person was thinking in terms of a temporary rego permit which usually allows you two weeks to move an unregistered vehicle from one point to another. If it was me I would take the free 12 mths rego in Qland, take my time getting home, then take it to the S.A. transport place nominated and tell them that you bought the van in Qland and now wan't to transfer the rego to S.A. rego. That should not be a problem unless there are some standards that the van must comply with in S.A. and need to be brought up to spec, you would need to do that in any case. Also there may be some financial differential you may need to meet. I would quiz the mob you are buying the van from I bet they know and get back to S.A. transport and findout what the exact situation is if you rego the van in Qland then want to transfer the rego when you return to S.A. When you contact S.A. transport have a list of questions ready to ask them so you don't forget when you are in the midst of a conversation with a person who will probably only tell you the minimum amount of information so the they can move onto the next person in the queue. Whew! Does that help yo a bit?

Ok here is your answer. I purchased a car in Queensland and to get it into my name I had to prove by way of a document that I had a Queensland address.
What was acceptable was a credit card receipt and invoice from the motel where I stayed the night before and a story to the very helpful rego person on how we didn't have a permanent address in Queensland as yet and that we had bought a car up there and were going to drive until we found an area we liked and then we planned to move up there. We were then able to have a postal address in Adelaide to have the papers/disc sent to.

Did the same thing with a NSW rego'd camper a few months ago with the caravan park receipt.

Now the thing is if you can get it into your name in Queensland then when you get back to Adelaide you don't need to take it to regency park. They will just transfer it over if you give them the papers and the plates which is a lot cheaper

Now there is a downside. If it is in Queensland rego there is no third party cover if towed with an interstate rego'd vehicle as in Qld the trailer TP insurance goes with the car TP.

I agree there should be a national system and now we have moved up to Qld it has cost heaps to change over the car which ended up SA rego and the camper NSW rego not to mention the/gas compliance certificate.
