UPDATE 2.25PM: A COUNCIL prime mover and trailer valued at more than $400,000 have been completely destroyed in an early-morning blaze.
A council spokesman confirmed the fire, saying it appeared to have started in the 85 cubic metre trailer.
He said a council worker was filling a water tank on a street sweeper near by when he saw the flames and raised the alarm.
The vehicle was a 2016 Hino FS2848 Short Proshift 16 Air Prime Mover and the trailer a 2014 Azmeb high-volume Side Tipper.
The spokesman said the side tipper was a locally manufactured product from Azmeb Global Trailers in North Bundaberg.
He said the council would be unable to remove the vehicle until insurers have undertaken an assessment.
The prime mover and trailer was valued at $422,000.
Police are investigating the incident and said they had not ruled out arson.
"We can't discount anything at this point until we have done a full range of tests," Acting Inspector Michael Bishop said.
EARLIER: IF YOU heard a loud bang in West Bundaberg early this morning, you are not alone.
Social media users were quick to jump on local forums to ask about the "sound of a loud explosion" in the area.
Queensland Fire and Emergency Services confirmed the big bang was from a truck fire at the Bundaberg Waste and Recycling Facility on University Dr.
QFES spokesman Ross Findlay said the truck caught fire under the garbage loading chute at the facility early this morning.
"We were called to the fire about 2.30am," he said.
"A council worker saw the blaze and by the time we got there, the truck was well involved."
Mr Findlay said the explosion heard by residents was the tyres of the truck "blowing out".
"It was definitely a loud bang," he said.
"It was made even louder because of where the truck was, it caused quite an echo."
Mr Findlay said two crews battled the blaze and the truck was completely destroyed.
The estimated value of the truck is more than $400,000.
