As her daughter played piano and her granddaughter sang, Mrs McElwee's friends and family from across the nation joined in the celebrations.

"I'm having a wonderful day with all my wonderful relatives that I hadn't seen for years," Mrs McElwee said.

"I live for my family."

Living in Launceston for most of her life, Mrs McElwee said that one of her happiest memories was meeting her husband of 64 years, the late Reg McElwee.

The couple met while both working at the textile factory Kelsall and Kemp.

Music has been a passion of both Mrs McElwee and her family throughout her life.

"Music's always been part of the family," Mrs McElwee said.

"I still play the piano a little bit."

Since moving into the Sandhill Aged Care Home in 2011, Mrs McElwee's daughter Valerie Towers said that she had enjoyed the change.

"She absolutely loves it here, she's thrived since she came here," Mrs Towers said.

"She has devoted her whole life to her family."

"The staff here are very, very good," Mrs McElwee said.

Mrs McElwee's good health has given her the rare opportunity to meet her two great-great-grandchildren.
