I'm in Sydney, NSW at the moment. Last night we took a trip to the Blue Mountains to find glow worms, which we did. They live in a sandstone gully, about 20 minutes walk in from a camp ground. It was a magical experience, thousands of tiny lights glowing away, a few feet from us. On the walk back my niece says "ooh, there's a snake", mostly because there was one, wriggling across the path. At first she thought it was an Eastern Brown Snake but then changed her mind and pronounced it a Red Bellied Black Snake. I bravely hid behind her.
Earlier in the week, we went down the Paramatta (?) River in a RIB towards Sydney in the evening. A big flock of what I assumed were birds flew over head. No, they were bats. Huge bats, like out of a Hammer Horror, with wingspan of about a metre. Google suggests they were either Grey Faced or Black Flying Foxes.
