The paramedic's own colleagues and friends tried to save him on what the Queensland Ambulance Service has described as one of its darkest days.
The paramedic suffered critical injuries and died at the scene."You would not get any worse circumstances in a day's work than attending a colleague in such horrific circumstances," the Queensland Ambulance Service's Gerard Lawler said.
"Today is one of the saddest days in the history of the Queensland Ambulance Service."
Colleagues and friends have been offered counselling and time off to process their grief, as the ambulance service rallies to support those he has left behind.
The victim has been saving lives for almost a decade and was described as a diligent and professional worker.
