$137.18 US for the hard drive plus $7.86 for shipping to Australia. Remember to turn off Amazon's currency converter and pay in AUD, as you'll almost certainly get a better exchange rate from your bank or credit card. Amazon's current exchange rate is 1 USD = 0.9821298433 AUD, which is rubbish!
The link above is to the general Amazon website because the OzBargain submission form would not let me post a link to the product, claiming it had already been posted (yes, but that was on a different date and for a higher price!), so the actual link to the hard drive is here: http://www.amazon.com/gp/product/B005HMKKH4/ref=ox_sc_act_ti…
Why is 1 USD = 0.9821298433 AUD rubbish? From this that means 1AUD = 1.018 USD. Order in AUD is 142.45. Your bank will take AUD 142.45 from your account.
Order in USD = 145.04. If you have bank that gives you Close to market, says 1.035(which is bad already), you only paying AUD 140.13. Market currency exchange for this order is at AUD 137.15.
