If one used the first edition exhaustively and went to every location recommended, as I did myself with other SA birders, there can’t be too many new places for the new edition to cover. I sold my original once it was out of print and had served its purpose.
I’m with Carl on this. And if it’s got errors like the Yumbarra one where you should go through the gate at the end of Foggo’s Rd before turning left ( then travel 2.1km along the fence before turning right up a poorly marked narrow track etc), Hm!
