If you are looking for a free trial version of Microsoft Office 2010, then this is the link that you will be needing, for the Australian version:
Comparing Microsoft Office 2010 to the older 2007 version, I haven’t seen much difference yet, but then again, I haven’t spent much time looking at it either.
Q: How long does the trial version last ?
A: A good question, and only partially answered by Microsoft’s answer here:
The Trial software needs to be activated within the first 30 days after the installation to utilise the full functionality of the Trial software.
The trial period will begin when you activate the trial and during the activation process, you will be notified of the trial expiration date.
Trials can only be activated when connected to the Internet.
To activate online, follow the instruction in the Activation Wizard that you are prompted with when opening an Application (like Word, Excel, etc.)
Microsoft Product Activation is a Microsoft anti-piracy technology designed to verify that software products are legitimately licensed.
