A Defence Force army major has died following a traffic accident in Canberra at the weekend.
Major Aaron Couchman was off duty and cycling when the accident happened on Saturday morning.
Army chief Major General John Boswell said Mr Couchman joined the army in 1990.
"As a man he embodied drive and professionalism," Mr Boswell said.
"He was a good bloke, a friend and mentor to many. He will be sorely missed by those of us fortunate enough to have known him."
Mr Couchman was posted to HQ Joint Operations Command in Canberra and had previously held senior positions at the Training and Doctrine Command in Waiouru.
Mr Boswell said the focus now was on supporting Mr Couchman's family.
"Our thoughts and our full support are with Aaron's family, friends and colleagues," Mr Boswell said.
