We chose to be an easy walk from the loo. It was a very solid construction, so there was no chance of the door blowing open!
There were a few notices inside, including a warning about the local dingoes and how to behave safely around them.
I read the notes but even so wasn't really expecting to see any dingoes, so was a bit startled to hear them howling later during the night!
On our nightly walks to the loo, we saw many trap-door spiders on the ground. They were all different sizes and noticeable due to their blue-jewelled eyes. If we shone a light directly upon them, they would scatter quickly back to their homes. Every so often we would catch sight of one shutting it's door firmly!
