My guess is a larva of Chrysodeixis argentifera. Only a guess though.
I think it's a Green Looper / Chrysodeixis eriosoma. Little bastards go through herbs like seagulls with a bag of chips, and they're all over Australasia.
Nature and Gardening
All things green, outdoors, and nature-y. Whether it's animals in their natural habitat, hiking trails and mountains, or planting a little garden for yourself (and everything in between), you can talk about it here.
