After reading around it seemed a good idea to get a Camping Card International (CCI). A CCI gets you discounts at a number of campgrounds in Europe, has some insurance associated with it, and (apparently) can be handed in in lieu of a passport at dodgy Balkan campgrounds that want to hold your ID hostage. To quote the CCI website, it “has the same value as a passport for the campsite owner.” It seems to be a fairly common thing in Europe, but not so well known in Australia. You can get them from your local automobile association, so I went into NRMA and hung around for an hour and a half while they found the form. They required me to get NRMA membership, which doubled the cost of the card, but I only needed to get one between Millerine and myself.
Anyway, same value as a passport? My arse! I’m not sure if it will be accepted anywhere we try to use it. $50 for a card with my details (handwritten), laminated to look pretty. Dodgy!
Edit: It was a little troublesome, but sometimes necessary. You’re better to just get one at the first place you need to use it.
