Buying our Paris Metro Card (Paris Visite) before we left for our trip was one of the best things I did.
We had to come through Paris a couple of times on our trip, so I bought a selection of 2 and 5 days tickets. The fact that we already had the tickets meant that we just had to worry about where we were going on the train, we didn't' have to think about our lack of French, whether or not we had change or even about pick pockets. I had the tickets in my pocket with my hand over the top, ready to go. We didn't have to stop and look around like tourists.
The one time we had to purchase a ticket (to get to Orly airport) we were faced with long lines, no change and we were eventually scammed and lost €20. My only regret in our whole trip was that I hadn't purchased the 5 zone Paris Visite for our last day, then this would could have been avoided.
My son is off to Paris in a couple of months, I will not let him leave Australia without his pre-purchased Paris Visite cards! We are then joining him in December and we will not leave Australia without our pre-purchased Paris Visite Cards.
For any Australians planning to go to Paris and use the metro (which is convenient & easy to use) - my number 1 tip would be to pre-purchase your Paris Visite cards from Rail Plus. 100% satisfaction guaranteed.
