I recommend going a little later in the morning when the sun is high, as on the way in there are some gecko and skink displays and they were quite hard to find. We got there at 11am or so and could only see a few but nearly an hour later on the way out the sun was brighter and more of them were out sunbathing in the tops of the bushes.
We saw another wasp with exactly the same sort of spider on another bush walk too, creepy
