Part of CentreCom's end of financial year clearance. Hitachi Travelstar 5K1000 1TB - 5400 rpm, 2.5 inch hard disk drive for $59. It is cheaper than the 3.5 inch equivalent and MSY is selling the same drive for $85. Obviously, no where near as good as the Aust Post clearance deals.
Only worth considering if you already have something to put the drive in. If you are after an external hard drive, it is not cost effective to get this.
As Proculeius pointed out, the crazy shipping cost means it is only worthwhile if you live near one of the Centrecom stores.
Also, Astone AW-N290 Wireless USB is $8. It might be handy for people who own Astone media players.

Might be a good replacement drive for a PS3 if you're running out of space too.
