Touring maps of Victoria

[crazney]

Does anyone know where I could find some detailed touring maps of Victoria?

I'm specifically interested in something that is light and easy to carry on a bike, however a book type thing would do - I could photocopy relevant parts.

I'd like a map that is fairly high in details, preferably showing things like camp grounds and so on..

At the moment I'm looking for such a map of the Great Ocean Road - but this is more of a general question.

Thanks

David
