If you know the city where she/he died, do a google search for the local newspaper there... If it's a small town you might have trouble online and you might have to get it sent but all of Australias big newspapers are available on 24/7

Try www.heraldsun.com as you can search most states there, or www.theage.com.au

Any problems please let me know and i'll see if i can track it down for you.
