The Coffs Harbour Butterfly House website has a resource for anyone trying to identify caterpillars, moths or butterflies. If you're ever trying to pin down the identity of a caterpillar in your yard try visiting http://lepidoptera.butterflyhouse.com.au/
The database here is by no means exhaustive but provides a fair cross-section of the more common species that you might come across.
