Caravan Gas Certificates and Roadworthy Certificates

Caravan Gas & Roadworthy Certificates

When do I require a Gas Certificate for my caravan?

You will require a caravan gas certificate when:

  • Purchasing a caravan that has never been registered
  • Transferring the caravan registration when moving from another state or territory
  • The caravan registration has expired more than 3 months before
  • When buying or selling a caravan

Note: a caravan gas certificate is only required if the unit is fitted with mounted or fixed gas lines, appliances or regulator.


How long is a caravan gas certificate valid for?

A caravan gas certificate is valid for 3 months. Note the gas certificate is a one use document, which means it can only be used once when processing with Queensland Department of Transport.

What if my caravan does not pass the inspection first time?

FreezeTec have a great team of highly qualified gas technicians and most of the time they can complete any necessary repairs at the time of inspection to get your caravan compliant. Cost of repairs will be in addition to the inspection cost.

Queensland Department of Transport allow 14 days from the first inspection to have any defects repaired. Once this work is completed FreezeTec can complete a second inspection (at additional cost).
