She came to live at Brightwater the Cove five years ago and celebrated her 100th birthday on September 27 with Cove staff members and other residents.
Mrs Sullivan was born in Fremantle in 1913.
Before the war, she was an apprentice photographer until the company she worked for had to close down during the Depression.
She went to work as a shopkeeper and later as a cook at the Imperial Hotel in Fremantle.
Mrs Sullivan met her husband on a blind date.
Even though he did not show up for the first date, she gave him another chance and they got married in 1937.
Mrs Sullivan said she had an eventful life, one of the highlights being a trip in 1964, when she and her husband drove around Asia and Europe in a kombi van.
She said the best thing about living at the Cove was the carers.
‘They are all marvellous,’ Mrs Sullivan said.
Her favourite activities are Wii bowling, bingo and training for the Seniors Recreation Council Live Lighter Aged Care Games, which are held every year in the Peel district.
Last year she nearly won the title of the eldest person competing in the games, but missed out by one year.
She is hoping to be able to gain that title this year.
