Police said a 54-year-old man died after he fell into a woodchipper.
The 54-year-old Queensland man was clearing the driveway of a rural property in Goomborian, Gympie - about 660 miles north of Sydney - with two friends Sunday night when the incident occurred.
"Everyone's obviously very distressed and we're still trying to work out the circumstances as to who has seen what".
Authorities are investigating to determine exactly how the man was pulled into the machine, and whether he was using the woodchipper properly.
Mr Algie said the man's two friends were "extremely distressed". The guys were not contractors and knew the lady who owns the property, police said.
"They are obviously quite traumatised now".
First responders and anyone investigating the incident have also been offered support services.
Acting Inspector Paul Algie told The Gympie Times the scene was one of the most horrific he'd ever come across.
He urged the community to take care around machinery.
Mr Algie said: "There's very clear guidelines in terms of the paperwork that comes with these machines and also I noticed on the trailer there's a number of warning stickers in relation to how the machine should be used".
A report is being prepared for the Coroner.
QLD Workplace Health and Safety have launched an investigation into the incident and, in a profoundly grim note, the Disaster Victim Identification Squad has joined forensic officials at the site of the incident today.
