I was listening to the radio the other night and they were interviewing a lady from the National Library of Australia. She was focussing in the interview on Genealogy; but remarked how amazing the NLA site was.
Anyway, I have been on for a look and what a recource it appears to be. Contains SO much rich Australian history and real-world documents which trace all things Australian and much, much more (I sound like an NLA employee!).
Anyway, it looks fantastic and can be seen at:

Check it out!

On further investigation it would appear you need to acquire a library card – simple enrolment process – in order to access files and information. More than just a History resource, it does look very useful and promising.
