Not sure of the answer for that but we are in the process of buying tow vehicle and have organised mechanical pre-purchase check.
Did notice that they check caravans too so maybe for peace of mind you might want to do that.

If you say which state you're from you'll get responses that are more relevant to your situation.

In NSW a roadworthy is required every 12 months and in the case of cars etc (and to the best of my knowledge, caravans too) when the vehicle is being sold, the vendor being responsible for the certificate.

Note that a current registration certificate does not confirm title, you'll need to do this research yourself.

If check the relevant website of the registration authority in your state you should find the answer there.

We had to get a roadworthy("Blue slip") when changing rego from ACT to NSW, and it was a big hassle as they noticed the tare weight on the ACT rego slip was 300 kgs more than on the compliance plate! the Dealer had registered it when new, and we never checked the weight stated on the slip. So we had to empty the caravan, including draining out all the water, and take it to a public weighbridge. The compliance plate is correct.

Once the correct tare weight was established it was no trouble to register the caravan.

Lesson... ALWAYS check the documentation against the compliance plate when purchasing either a new or second-hand caravan!

I don't know whether we've helped the original poster or not. She has not come back to the thread to either let us know which state she's in or even if she's read the replies.

No Roadworhy checks apply to light trailers (Caravans) in Victoria, but the vendor (In all States) is responsible under consumer law to supply goods of a "Merchantable Quailty"and  "Fit for Purpose" and thus should be supplied in a Roadworthy condition.
