So after a 3km walk around the escarpment (that's a cliff to the uninitiated like myself), passing waterfalls at every corner, we started the descent to the coast. As you've probably guessed by now, Aussies don't do things by halves, and after a few kilometres of steep descent the van started emitting a funny smell, probably just the brakes on fire!
The bottom of the hill was Kiama, site of two blowholes, where the rock allows waves underneath and up through a hole. The larger blowhole looks like the Sarlacc (sand beast) from Return of the Jedi, and every so often a big whoosh is followed by a jet of water squirting up. The smaller blowhole is only about a foot square, but the water squirts higher and the whoosh is louder - it's also easier to hear without everyone oohing and aahing in the background!
