Only a few fighters have had a successful professional boxing career after the age of fifty: George Foreman, Bernard Hopkins, and Dulwich Hill's Father Dave Smith.
He enjoys the physicality of the sport but it is seeing its impact on the lives of his parishioners that keeps him in the ring.
Now 55, Fr Dave continues to train and professionally box while fundraising for his own community and Syria which has become a focus for his charity work.
He is a fighter, an Anglican preacher, a youth worker, a father of four, a trainer and a priest.
Chris Turner, first entered Father Dave's boxing academy in September last year and their friendship was instantaneous. "It felt like we had been friends for many years."
"From the moment I contacted him, it's like we were old mates. First time I met him, he embraced me and called me brother," Mr Turner said.
Since then Mr Turner has been coming to the gym regularly and has felt a strong sense of community.
He intends to accompany Fr Dave on his next trip to Syria and has found new meaning in his life.
"In 1989, I was sent to Dulwich Hill, by the parish ... I started asking people about the problems in the area," Fr Dave said.
"Many were concerned the youth in the area had nothing to do after school, so we started working with kids," he said.
Fr Dave had a background in Korean Martial Arts, with a 6th degree black belt. But after the breakdown of his first marriage, boxing training and competitions became a form of healing.
He noticed the positive effects of boxing, and the problems in the community... substance abuse, fathers fighting for custody and anger issues involving young people.
It prompted him to the Old School Boxing Academy which continues to work its magic.
The connection with the youth was the reason he fell in love with boxing. It was a way of getting to know more about the community. Some of the children he dealt with were on the verge of becoming involved in the drug scene or ending up in prison.
"We felt fight training would be good for them ... they had to have two things, a lot of energy, and not to be too concerned about their good looks," Fr Dave said.
He's a man of faith but embraces fighters from different races, religions, beliefs and ages. However, in the gym there are no differences except for skill and experience.
His work as both a humanitarian and trainer have inspired some of his fighters to better themselves as members of the community and individually.
