The bodies of a father and his 10-year-old daughter have been found following a shed fire at a rural property northwest of Brisbane.
Emergency services were called to the property at Biggenden, west of Maryborough on Tuesday afternoon before making the grim discovery.
Speaking to reporters on Wednesday, Detective Chief Inspector Gary Pettiford said the 54-year-old man who died was due to marry his partner and the child's mother next week.
"The whole thing is very tragic for the community out there ... they were actually getting married at the property," he said.
The woman involved is distraught and in shock, Det Chief Insp Pettiford said.
"It will to be a long time before she comes to terms with the loss of not only her partner but her daughter," he said.
Once it's safe to enter the structure, forensic experts will begin to gather evidence and the remains will be retrieved.
The cause of the fire is currently unknown.
"This investigation will go for at least two to three days before we'll know anything concrete," Det Chief Insp Pettiford said.
