Victor Harbor's Irma Springbett turned 100 on Monday, November 4 and celebrated the milestone with family and friends on Sunday, November 3, at the Encounter Bay Football Club.
However the party started early for Irma, when on Friday, November 1, the team at Coles Victor Harbor, surprised Irma when she went to do her normal weekly shopping.
Led by manager Rob, the Coles team presented Irma with a '100' birthday cake, flowers and chocolates.
However, on the Sunday, more than 170 people turned up to honour the centurion at Encounter Bay.
Irma has three children, Malcolm, Richard and Marilyn, 11 grand children and 23 great-grandchildren.
Irma said it was emotional to share her 100th birthday with family and friends and that family was the secret to her longevity.
"Family life is everything to me," Irma said.
"Over the years all the pleasure and entertainment I have enjoyed has revolved around my family and other families we knew.
"I am so fortunate, as I love my family and it was so special to share my birthday with so many people."
When Irma cracked the ton on Monday, November 4, she also shared the special day with her son Richard.
Richard turned 75-years-old on the same day, but in typical Richard manner, wanted the day to be all about his mother.
"I think it is pretty special for Mum to have her grand kids and great-grand kids here for this special day," Richard said.
