"The family are, of course, deeply distressed and have asked that their privacy be respected at this time," a spokesman said.
The arson squad is still investigating the exact cause of the blast.
The family had been staying at the caravan park for at least a week as they sought more permanent, rental accommodation.
Witnesses told reporters on Wednesday how they heard a bang, like a bomb going off, and then saw a yellow flame engulf the tent.
"I just tried to find a hose, so that I could help," Tony said.
"We all just tried to put out the fire."
Sharon Doyle, who was staying at a nearby house, said she could hear the father and daughter screaming.
"People were yelling out 'help, help me' ... the daughter was more whimpering," she told reporters.
"It was just horrible. Trying to get those sounds out of your head is hard, even now."
