Gloria May Dawson

I am trying to find a 'Death Notice' of my Aunty 'Gloria May Dawson'. Her husband's name is Kenneth James Dawson, (also deceased) . The last record I have of Gloria May Dawson, is the 1963 Australian Electoral Roll, and they are listed as living in Spurwood Road, Warrimoo, NSW. but am unable to find anything else.

Any help would be appreciated.

Thank you, Bronnie
