An Australian man working as a combat medic assisting frontline troops has been killed in Ukraine.
Queenslander Jed William Danahay, 27, was killed on August 24 in Izyum in eastern Ukraine by Russian forces while driving a medical vehicle, his family says.
"Jed lived his life trying to help other people. In his short time on this earth Jed did more things than most of us will ever do in a lifetime," his family said in a statement.
"Jed's comrades in Ukraine described him as the backbone of their unit, a hero and someone who they could all trust their lives too."
The medic died for what he believed in, helping people who needed it, his family said.
"He was at his heart an optimist and always believed that things should be better," they said.
"Jed's comrades in Ukraine described him as the backbone of their unit, a hero and someone who they could all trust their lives too.
"He will be missed dearly by his friends and family."
The Department of Foreign Affairs and Trade is providing consular assistance to the family, which can include guidance and liaison with local and Australian authorities to assist with funeral and repatriation arrangements.
"We send our deepest condolences to the family and request their privacy be respected during this difficult time," a DFAT spokesman said.
