Never one for much fuss, former Wimmera resident and World War II veteran Jack Bullen will hold just a small event in celebration of his monumental achievement on Friday.
Becoming a centenarian is a major feat for any individual, but Mr Bullen said he planned to have just a small get-together this weekend, seeing the funny side of his milestone.
"I'm still upright," he said.
"I don't hold much thought for celebrations, I've had too many of them anyway. But my daughter and my son are coming down and we'll have lunch together."
He said he'd been overwhelmed with the number of cards and letters he'd received.
"It's never-ending," he said.
"I got a letter from the Queen, from the Governor General, from the Prime Minister, from the Premier of Victoria and three local members.
But with a lifetime of involvement in committees, clubs and the military, Mr Bullen should hardly be surprised at the community's response.
Mr Bullen, who now lives in Warrnambool, enlisted in the army in Horsham in 1940, lying about his age in order to join.
"I went into the office and the fella said 'how old are you?' I said '18' and he said 'go home and wait a couple years'," Mr Bullen said.
"So I walked out of his office and walked back in and he said 'what do you want?' and I said 'I'm 20' and he said 'sign this'."
As a driver in the 9th Division Cavalry Regiment, it wasn't long before Mr Bullen saw battle in Syria.
"I had five-and-a-half years in the army, I was in the Middle East for two-and-a-half years and in Borneo in the Pacific," he said.
"After the war, I opened a General Motors dealership in Nhill with my brother all the way until 1984 - we had a big business there with 32 staff."
While in Nhill, Mr Bullen filled his time by engaging with a range of activities, clubs and societies.
"I was president of almost everything but the girl guides I think," he said.
"I was president of Rotary, of the RSL, the golf club, the hospital and I was on many committees. I was also vice-captain of the local football team."
Mr Bullen moved to Point Lonsdale shortly after retiring in 1984 and stayed there for 20 years before finally settling in Warrnambool.
He's heavily involved in the golf club, having played the sport for 82 years.
At age 92, he even won the Warrnambool Golf Cub open competition.
