My vote is for Lakes Entrance.
Heaps of places to eat, nice scenery, nice flight, 2 airstrips to choose from, both are good - 1 bitumen new and the other grass, close to town (short taxi ride). Lots of 90 mile beach to fly down on the way there and back. How can I say.... it's often "deserted" beach if you get my drift.
Apollo bay is about a $15 taxi ride from town, 700 metres, downhill / uphill depending on how you look at it. Need to ring ahead because there's lots of seafog there at the moment which makes it hard to get in sometimes. It sticks to the beach like s*hit to a blanket, even all day.
