'Act of revenge' fuels fatal Qld explosion

An alleged act of revenge has cost a man his life in central Queensland after fuel he was using to set a shipping container alight exploded.

The Mackay man's body was found at a trailer manufacturing business by firefighters about 2am on Tuesday.

Police allege the fatal explosion happened while the man, 30, was attempting to ignite a container holding personal items belonging to his father's ex-partner.

"Unfortunately, in the process of lighting it's obviously got out of control and there was an explosion," a spokesman told AAP on Wednesday.

The dead man's father, Timothy Ian McIntyre, 50, was also at the Malcolmson Street business and helped set the fire, police allege.

"We'll allege they planned to run in different directions when the fire was lit," the spokesman said.

"So it appears (McIntyre) didn't know the tragedy had occurred."

Police charged McIntyre with a string of offences, including arson, wilful damage and four counts of contravening a domestic violence order.

He was remanded in custody after appearing in Mackay Magistrates Court on Wednesday.

McIntyre will reappear in the same court on May 29.
