Commander Dawe attended Riverside High School and was a former Tamar Yacht Club member.

His career in the navy has spanned over 45 years of service.

Commander Dawe's father Max Dawe was one of the founding members of the Trevallyn Bowls and Community Club.

He said Commander Dawe will be the first person actively serving in the armed forces to speak at the event.

"All the people we've had previously have been ex-servicemen or somebody tied up with the services like politicians," Mr Dawe said.

"This is the first time."

Naval service runs in the family, with Commander Dawe's older brother also serving in the navy for 30 years.

"His brother had already been in the navy for three years," Mr Dawe said.

"Gavin was more interested in sailor than his brother.

"Gavin used to as a school kid go in and out of the naval office and have a look at pictures - all the officers knew him.

"That's his life and he just loves it, I mean he's been in the job for 45 years."

According to Mr Dawe, his son was too young to be in the navy when he was first accepted to attend academy training.

"He was in there for six months and two weeks before they found out he was too young," Mr Dawe said.

"They [the navy] said 'you might as well stay now' two weeks after he's reached the proper age."

Commander Dawe was made an officer of the Order of Australia when he was 27.

Mr Dawe said his son received the honour because of his involvement in developing something related to anti-submarine warfare.

Commander Dawe has recently become involved in the Young Endeavour Foundation and youth development program, even captaining the STS Young Endeavour on its 12 month world cruise in 2015 that visited Anzac Cove.

Mr Dawe said family members from across Australia will be coming to Tasmania during Anzac weekend, many of whom are current or former members of the navy.

"They sort of planned it around that [Anzac Day]," he said.

"It was a double-whammy so to speak.

"His [Commander Dawe's] wife used to be in the navy and his brother's wife also used to be in navy."

Trevallyn's Anzac Day service will commence at noon at the Bowls and Community Club, there will also be a $5 lunch and rum issue after the ceremony.
