Got an email with the above HDD at 51% off for $159.95. Shipping to my location was $10, I didn't put it in the description because I'm not sure if it'll be different to other locations.
It looks like it is the same drive as the one office works had on special (see: http://www.ozbargain.com.au/node/81192 )
This one will be a bit more expensive due to the postage but still a good deal.
Urr.. I just picked one of these up for $159 at officeworks 2 days ago.
