Hi there,
I am in NSW Australia ....
There are restrictions on obtaining dcs in various states .... usually 30 year closed .... Of course there are newspaper indexes for death, funeral notices ... one online index is
http://www.ryersonindex.org/There's a 1981 notice indexed at that link ....Abraham SHAPIRO death 19 Jan 1981, late of Maroubra (a suburb of Sydney). The notice appeared in the SMH newspaper on 20 Jan 1981. That newspaper notice may be one of several for that chap.... there may be a separate notice for the funeral service, this could be several days later in January. There may be a probate/administration notice ... that could be several months after.
The ryerson index is prepared by volunteers, and there is a look up facility that the volunteers conduct, and is listed on their website. I realise that "Abraham" is not "Isaac", but these two names are familiar to many
and often go hand in hand.
If you think there may be a connection between Abraham Shapiro death 10 Jan 1981 and Shazzafitz's post "my father died in 1981 all alone in Australia", perhaps there's RChatters on the Aussie Board who can help with a visit to one of the major libraries in the various state capitals.
In the meantime, I will see if I can find any likely online sightings of an Isaac Shapiro in Australia post WWII ...
Cheers, JM
