Odd, I thought they'd all been guessed correctly!
1) Looks like a ghost bat, probably at Perth judging from the red light, only thing throwing it off is no ears hanging down but this looks like an underside view with the bat looking up.
2) It's a megapode...on the beach, what else could it be but a maleo?
3) Coloration is consistent with a New Caledonian (goliath) Imperial Pigeon.
I'm stumped!
