I don't know if it's any help but you can look up NSW Births, Deaths & Marriages at www.bdm.gov.au and click on indexes. If you have a district it would probably help. Births you can search up to 1905, Deaths & Marriages up to 1945. I've had some great results from here. There was also a similar site for searching in Tassie but I've lost the link and can't seem to find my way into the site again. I will keep trying and let you know if I find it. Hope this helps.
