How would one go about purchasing an electric eel or two in Victoria, Australia?

It might be a folly, but I seem to have decided that I want an electric eel in my new giant fishtank. Is there a supplier in Australia that you know of, a friend? A friend of a friend who knew your cousin Larry? Short of importing on from the Amazon at great cost, I've got nothing. If anyone could shed some light on the situation (Pun, oh dear..), I would be most pleased!
