I've missed most of this thread, unfortunately ($($*&!@^ Ozemail doesn't
seem to keep many posts from many groups for very long these days!) but
this is a great site for anyone wanting to identify something:

The insect section is particularly good and the staff at the museum were
very helpful to me when I was trying to identify a particular kind of
eel a while back.

The link on the right: 'Encyclopaedia of Australian Reptiles' might be
of especial interest here.
