Many large IT suppliers provide discounts on both hardware and software. Examples include:
Apple: http://store.apple.com/au-hed
Lenovo: http://shopap.lenovo.com/students/au/en/deals-and-coupons/students-spec…
Dell: http://www.dell.com/learn/au/en/aucorp1/campaigns/students-platinum-au
Microsoft: They have special student only & student/home versions of their products - can be purchased online or at stores. E.G. $99 for a 4 year Office 365 subscription for two pcs/macs (http://www.microsoftstore.com/store/msaus/en_AU/pdp/Office-365-Universi…)
Adobe: http://www.adobe.com/au/education.html
Note that sometimes you may have to provide proof of being a student - usually this is easy enough to do either by having an education email address or sending a photocopy of your student ID.
