Some great pics there, makes me miss it a little
It is nice down there, but as you say, you tend to get fed up with nothing but trees after a while!
Oh and watch out for those bloody march flies too, those buggers have teeth, are about an inch long, and take chunks out of you.
You can hear them coming about a kilometre away, they sound like bleedin chainsaws - ruuuun
A good overnight trip is to camp out on Forrest beach just outside Busselton. Take a crab scoop with you, and a small gas cooker and pot for boiling up the crabs you can catch. It's really easy, just walk along the waters edge once the sun goes down and shine your torch into the water. If you see a dark spot, hit it with your scoop. Three or four crabs make a great supper
You can camp on the beach, but stay away from the dunes, the Rangers don't have a sense of humour as they're out of bounds.
