Having read the title of your post I thought I knew what the subject matter would be. how wrong I was.
Dandy seems to have been a popular name in camper or RV sales. Every once in awhile a member will sport the Dandy RV dealerships in America [You must be registered and logged in to see this link.]
or the more local to you (hardly in your neighberhood though) Just Dandy Camper Trailers. [You must be registered and logged in to see this link.]
These are taken as points of amusement but I never expected to see a question from an Australian asking about if Dandys are or were ever exported to Australia.
1) Dandys aren't been made new anymore so there couldn't be an active dealer.
2) They were never made in massive numbers with the majority being for UK consumption though there was a dealership in the Netherlands. Hence one or two also crop up in France or Germany.
3) I may misunderstand the nature of Australian topography but from the advertisements or features I've seen on Australian kit a Dandy is the last thing that you would want. I realise that you would be towing with a normal domestic hatchback but all the stuff I have seen from Australian features has much longer travel suspension and is built for towing over poor surfaces. I actually have little idea if you have a vast high quality highway system or if roads tend to turn poor a few miles out of urban areas. I realise ads and features can be deceptive. In British camping features manufacturers will boast how their petrol stove shaves seconds off boiling a pint of water. None of them talk about the much more useful feature of if they will simmer rather than just run like a rocket and burn stew to the bottom of your pan. I do understand some European caravans are imported but how well they cope I don't know.
For any features on suitable Australian campers can I suggest reading The Caravaners Forum (Do Australians spell Caravanners differently?) [You must be registered and logged in to see this link.]
I read this and use ideas frequently. I am embarrassed to say that the technical appreciation of posters looks much higher than similar British forums. Also Collyn Rivers has been known to post on there. Mr Rivers is one of the best sources of information I have found, especially his information on vehicle dynamics which he posts in a readable and understandable form.
Sorry that I say nothing more positive about your chances of finding a Dandy.
