A 24-year-old woman has been charged with two counts of murder after two bodies were found in a burnt-out shed in Biggenden, north-west of Brisbane, last month.
The fire claimed the lives of the town's baker, 54-year-old Todd Mooney, and his 10-year-old daughter Kirra on December 20.
Twenty-four-year-old Maryborough woman, Kristen Olsen, was also charged with one count of arson.
