Bushwalk Australia

We are thinking about walking a part of the Great Ocean Walk in September. What is the best way to do it over three days and two nights? We are thinking of starting at Cape Otway and heading west to camp at Aire River night 1 and then Johanna Beach night 2. Or is it better to start at Apollo Bay? Also I heard that you have to book and pay to camp (Tell me it isn't so).

This previous topic has everything that needs to be said about the Great Ocean Walk. By the Way, you do pay / book for the priviledge of camping / hiking.
