A former Sydney public relations executive who became homeless in her 60s says publicising her story led to a cascade of contact from regular, suburban women who had also fallen on hard times.

Glen-Marie Frost, 73, previously lived in a mansion in Bellevue Hill in Sydney's east, managed an international PR company and was head of communications and community relations for the Sydney Olympics.
