All new/unopened and purchased via Amazon AU via US(Samsung) and Amazon US(WD) so no local warranty.

Also happy to discuss purchasing on your behalf from Amazon US/AU to clear some gift card credit at 90% value(ie buying $200 item and you pay $180) as I have a fair amount of giftcard credit to use. I have a long trade history at gpforums and here with no issues.
