Hi, Ansellmw,
Welcome to Rootschat
Just to add a little to Sparrett’s post, you can search the Ryerson Index by district as well as person. For example there are 132 notices for Turramurra for the year 1986 - and all are in the Sydney Morning Herald rather than a local paper. Make sure you read the search instructions - you have to be fairly specific in regard to spelling etc. Once/if you find your relatives in the index just google for contact details. If you have any trouble I am sure there are people on here who will be able to help.
Cheers, Peter
