I’ve double checked with Samsung and due to its international warranty it is still covered in Australia. There is a depot in Hombush Bay, Sydney which you can send it to for repairs etc..
(You have to pay postage to the depot).
Hope this helps.
Also just an update- unfortunately Overclockers have increased their prices to ~$750 AU. Clove.co.uk now appears to be the cheapest overseas shipper at 255 pounds + postage (ex VAT already). Please let me know so we can share the word around if you can find any better deals.
Mine is supposed to arrive next Wednesday! Can’t wait 🙂
