ITS official: Lansvale's Annie Cairns is the oldest woman in south-west Sydney.
Born in 1909, the mother of three, grandmother of eight, great-grandmother of 25 and great-great-grandmother of four turned 105 on Thursday.
To celebrate the remarkable milestone, Cabra-Vale Diggers Club hosted a birthday party for her.
Joined by family and friends, the club's oldest member cut her birthday cake during a bingo break.
Her son Brian, 82, said he was thrilled with the wonderful reception. "I think it's wonderful — what an experience we've had," he said.
"When we were babies, Mum would look after us so if it was good enough for her to do it then, then it's good enough for us to look after her now."
His sister Vida Day, 80, said she couldn't believe her mother had reached 105.
"It's unbelievable," she said. "Mum still lives at home by herself but has people from home care visit regularly to shower her."
Adding to the surprises on the day, Mrs Cairns woke up to 105 balloons at the front of her house — a present from her neighbours.
Mr Cairns said a party was also held for his mother at her home later that day.
Mrs Cairns used to walk to Cabra-Vale Diggers Club three times a week.
She stopped doing so a year ago because of declining health.
In March, she collapsed at the front of her Lansvale home and had to go to hospital.
Since then, she has been in a wheelchair.
Mrs Day said her mother had deteriorated over the past year.
"She currently weighs 31 kilograms and only 10 per cent of her aorta is working."
