I am moving out to Adelaide at the end of November.
In the UK I use a website called ReaditSwapit to exchange books with other people. Basically you buy a book, read it, and then register it on the website for free. Anyone then can choose your book, and you choose one of theirs, and you swap books. All it costs is the postage for the book. At a rough cost of £1.80 a book it saves me a fortune in new books.
Does anyone know of a similar thing in Oz?
