A man was airlifted to hospital after suffering head and shoulder injuries when he fell from a ladder in northern New South Wales.
The incident happened on Friday afternoon.
Paramedics were called to the Barraba property about 4pm.
The man was stabilised on scene before being flown to a Tamworth hospital by the Westpac Rescue Helicopter.
Falls from a height caused 46 fatalities (or 30 per cent) over the five year period from 2013 to 2017, according to Safe Work Australia figures.
Over a third (35 per cent) of these involved falls from a building or other type of structure, and almost a quarter (22 per cent) involved a fall from a ladder.
