10.30 start, and then sunset is a long day at one spot, i think we need a second site for the earlier times and then a walk to the rocks for late afternoon. It not as if you can just wander back to the car from the rocks. There plenty of little benches to photography, weather permitting.
This makes good sense to me. But I don't know Phillip Island well enough to suggest other little beaches, beside that rugged coast around the penguin colony.
