Definitely sounds like the unit is dead. If you're within store return period, get them to give you a new one. Otherwise you should still be in manufacturer warranty (most digital products are 1-year), so call Nikon USA for a repair/replacement.
Edited to add: I just realized you're in Australia. Hmm. Well, forget the store and Nikon USA unless you want to pay shipping, which is likely prohibitive. See what the Nikon regional office in Lidcombe NSW can do. As long as you have a US receipt, they should honor warranty service.
