Hi,
Really,,if she is still alive we should NOT be talking about her and her private life on these boards.

We cannot access marriages after 1961 in NSW nor deaths after 1981.
So if she married or died after those dates your best hope would be newspaper notices.
If you know where she was living in 1980 google for local newspapers in that area and either ask for a lookup or place a notice.

If alive she would still be on electoral rolls BUT as we have no idea if SHE wants to be contacted it would be a bit rude of someone to give out her private details...((that is why the indexes stop at certain dates,,to protect people's privacy))
