Hi Angela,
I tried checking NSW for these people but marriages only go to 1955 and deaths to 1975. Although there is the Ryerson Index which has notices till now,,but nothing seemed to fit.
Maybe you should try a Victorian Site....I have the CD's but they won't run in this computer and the Vic deaths only go to 1985.
I did check Canberra cemetery on an off chance and nothing,, On the National Archives where it has Canberra,,,that just means where the papers are kept,,,,not where the people landed etc.
You can't catch a ship to Canberra,,,there is no Ocean here,,,hehehehe.
I know a good Vic site that may be able to help but alot get poopy about posting modern day lookups on Genealogy sites,,,Other that that I can get back to you when I get my CD's running.
Kellie
