Microsoft Office for students and staff has always been discounted and occasionally free, however it's usually a bit of a hassle. Office 365 is now available for students and teachers directly from the Microsoft website.
From what I can see the free subscription allows MS Office to be installed on 5 devices, which is pretty generous.
I tested my School email address (I'm a teacher), my uni email address and my daughter's school email address and they all worked.
I can confirm this is working for a large number of Australian education providers including schools, TAFE’s and Universities.
An Office 365 subscription includes the Office 2013 apps for PC and Mac (Word, Excel, PowerPoint, OneNote, Outlook, Access and Publisher) as well as 1 TB of OneDrive Storage and access to Office Web Apps.
Enjoy :)
