The Queensland Times report that the worker was driving a Mack prime mover loaded with treated logs and was using a small crane on the trailer to unload the pieces of timber.
According to Police, nobody saw what happened since the man was working on his own at the time of the incident. His body was discovered by other workers on the site at around 8.40am.
Ipswich district duty officer Senior Sergeant Bob Phillips said the man has somehow become stuck between the boom of the loading crane and the truck itself.
“It appears as though the man has somehow become stuck in between the boom of the crane and the rear frame of the truck,” said Snr Sgt Phillips.
“There were no witnesses but we believe it was a short period of time in between when the incident occurred and when he was found.”
The construction work at the Westside Christian College was stopped for several hours as investigations started.
Workplace Health and Safety Queensland is investigating the incident.
