Margaret Sinclair - who turns 106 on Saturday - said the secret to her longevity is drinking plenty of water and the odd glass of wine.
Mrs Sinclair, who lived in her family home at Petersham till she was 99, is a resident at St Vincent's Yennora (Rosary Village).
An active resident at that. Despite being wheelchair-bound, she still likes to dance, garden and read. She recently took part in the village's first gardening club and potted up baby seedlings.
Her sharp reflexes could easily see her captain the balloon volleyball team - not bad for someone who has lived through 28 Prime Ministers, two World Wars and the current toilet paper crisis.
Margaret was born in 1914 and grew up on an orchard in the little village of Thurgoona, outside Albury. After her father returned from World War I (where he lost an eye fighting in Belgium) the family moved to a vineyard called St Hilaire where she rode her horse to school at St Bridgette's Catholic Girls School.
Margaret, who is a life member of the Marrickville Historical Society, worked for an architect and a doctor and then as school teacher before coming to Sydney via a brief stint in Melbourne.
In her late 20's, she married her husband Ralph and they raised four sons in Glebe. Margaret and Ralph enjoyed many holidays together and travelled extensively through Europe before he died in 1976.
In 1948 the family moved to Petersham where Margaret lived until moving to St Vincent's Yennora (Rosary Village). Even when she was 99 she would walk down the street and hop on the bus into the city.
Margaret, who has six grandchildren and 14 great grandchildren, will celebrate with a small celebration on Sunday.
