Caution - booking via the internet doesn't always ensure accommodation is confirmed. We used a site called "takeabreak.com.au" which says (quote)
"You can book with confidence. All properties are verified by us and/or have been trading with us for an extended period."

Well, we flew into Melbourne, drove 3 hours down to Port Campbell to the Port O'Call Motel with an email confirmation to be told that there was no room for us and denying that the email confirmation was valid. Whether or not the motel had given away our room we don't know. But in any case, don't trust the booking site or - in this case - the particular motel in Port Campbell.

(NB. The website of course disclaims all responsibility for non-availability of rooms even with the above confident assurances!)
