Stories of service and sacrifice are inked on the skin of current and former military personnel across Australia.
The Australian War Memorial has created a photographic chronicle of the connection between tattoos and the Defence Force, with the results on display in a powerful exhibition.
"Tattoos have been such a central part of people's lives but have never been talked about," senior curator Stephanie Boyle said.
"It's an unofficial history hiding within the official military history."
The Ink in the Lines exhibition took about three years to curate and is on tour around the country.
It features the stories and tattoos of 22 people from across Australia, including Townsville veteran and tattoo artist Rob Douma.
"A lot of the tattoos that I've done for the veterans have been about helping them process grief, trauma, loss of mates," Mr Douma said.
"For others … it's all about that identity and belonging."
Despite more Australians being inked than ever, Mr Douma said there was still stigma around tattoos.
"I've travelled to other parts of Australia where I get stared at because I'm heavily tattooed," he said.
"There are still people of every generation that look at me like, 'What is that guy? Is he a bikie? Is he a criminal?'"
'Bridged the gap'
Ms Boyle said some people were surprised to find out about the War Memorial's exhibition.
"A lot of people disapprove of tattoos … [but] once they had listened to the stories and saw the photographs and understood the background of why someone – especially an ADF veteran – might choose to get a tattoo, their mind was completely changed," Ms Boyle said.
"It's bridged the gap between tattooed people and non-tattooed people, it's bridged the gap between veterans and non-veterans.
"People come away with an increased understanding of what it's like to be a veteran, but also what it's like to be a human being."
Brian Grace said he was overwhelmed and honoured to see photographs of his tattoos hanging in the Museum of Tropical Queensland in Townsville, Australia's largest garrison city.
"There is a lot of personal stress and a lot of suicide in the defence force, and a lot of these blokes [featured in the show] say their tattoos have stopped him from going down that line," he said.
Indelible thanks
Mr Grace has a large tattoo on his leg commemorating North Queensland's deadly Black Hawk tragedy in 1996.
"There were 18 fatalities from that and a number of the blokes from units that I'd served in were involved," he said.
Ms Boyle said the exhibition also explored the impact of service life on family members.
"We've got one person in the exhibition who's not a veteran — but she's married to one and she was so thankful for the safe return of her husband from Afghanistan that she wanted to embody that by getting a tattoo," Ms Boyle said.
"She said that it's not just for her, it represents all the families who worry and wait for their loved one to come home."
Ink in the Lines is on show at the Museum of Tropical Queensland until October.
