I found this Katydid in my garden yesterday. Going by photos I can find on the web the species appears to be the Common Garden Katydid (Caedicia simplex). However given that there are over a thousand katydid species in Australia, I'm not 100% sure. (I've got a big collection of flora and fauna ID books, but don't yet possess the Guide to the Katydids of Australia.)

Trigger plants (Stylidium graminifolium in this case) are fertilised by native bees or wasps. The petal arrangement resembles the wings of an insect and the flowers possibly send out a scent that entices some insects to attempt to mate with them. When a bee or wasp tickles the centre of a flower, the tensioned anther column flicks over whacking the amorous visitor with a puff of pollen. When this is repeated with another flower, the unwitting Romeo cross-fertilises them.
