International Light Fittings

I have no idea about electrical things, which I'm sure will be clearly evident from my question, but... If I was to buy a light fitting from another country and have it shipped over and installed by an electrician would it work or is the wiring different? Sorry in advance for a silly question.

My 2 cents and I am not an electrician :
Hmm without knowing what the item is...it's a very generic query and there cannot be a definitive answer. Consider following hiccup situations :
1) if from USA then default voltage is 110. So unless the fitting has an universal power adaptor (like the one a laptop has)..then the fitting won't work
2) if the fitting is not as per AU standards....it could be a problem enforcing any insurance claim
3) would you get any replacement spares locally ?
4) does the fitting require a specific type of electrical setup that your house does not support (e.g DC current or 3 phase power)

To mitigate the possible risks, you may want to ask the electrician prior to placing an order.

Thanks for your very detailed reply IamSAM, exactly the kind of info I was looking for. Much appreciated!
