UPDATE: A man's body has been found at the site of a scrub fire in City Beach.
About noon, firefighters were called to the blaze, which started between Rochdale Road and West Coast Highway.
Aircraft were sent to assist the ground crews, who quickly got the fire under control.
As emergency services mopped up, major crime squad detectives were called in to investigate reports of a body being found.
Residents said they heard an explosion before the fire.
The bomb squad visited the fire scene.
"We know some witnesses heard an explosion and, as a result of that, fire officers have attended the scene," Insp. Dominic Wood said earlier this afternoon.
"As a matter of protocol, police officers have attended to assist with traffic and assist to put the fire out.
"It is at that stage that fire officers have discovered that there was a deceased person at that location."
The man's death is not being treated as suspicious.
Insp. Wood said this afternoon that extra police resources were called to the fire scene.
"We’ve brought in the major crime squad and local detectives to come to the scene to start an investigation into who that person is and the circumstances," he said.
"At this stage we haven’t got close enough to fully ascertain how this person got to that location and the exact situation the body is in.
"We don’t know what the explosion is.
"It may be related to the subsequent fire ... we don’t know if there has been an explosion but because of what witnesses said we don’t want to take any risks with it so we always call in the bomb squad to thoroughly examine the area and make that safe for first responders, investigators and the fire officers.
"I don’t think too many people at this stage have seen anything specific but [they] have certainly heard an explosion so we have responded and acted on that explosion."
A parked van was found empty at the corner of Rochdale Road and West Coast Highway.
"Clearly a priority for us at this stage is to investigate that white van," Insp. Wood said.
"We don’t know if the van is linked to the deceased person."
