Hiya, I'm not yet required to be VAT Registered, I fall just under the threshold, which is one of the reason's why I don't export. Since there is no option of deducting the VAT for oversea's customers since I don't collect / charge it in the first place!.
The second reason, is that the cost of exporting would be prohibitive, it would possibly cost you the same as the effect in freight charges.
It's also worth bearing in mind that any warranty offered by Manufacturers is based on a RTB (Return to base) policy which means that the expense of returning the item to the supplier / manufacturer has to be paid by the customer. Worth considering if you buy anything from abroad and something goes wrong!
Beside's I thought that Aus / NZ was pretty much well set up for Audio / Lighting Equipment?. What are you looking for that you can't get locally??.
If you did buy from the UK - Our mains voltage is the same (230 - 240V / 50hz) but you would need to change the mains plug to suit your local system. Other than that it would work fine.
