The search for nine-year-old Charlise Mutten resumed on Monday morning, after the NSW girl went missing from a home four days ago.
Charlise’s parents say they last saw the girl on Thursday at a property at Mount Wilson, 20 kilometres north of Katoomba.
She was reported missing on Friday, prompting a search involving more than 100 police and emergency personnel including dog units, police helicopters and the SES.
Charlise is Caucasian, is between 130 centimetres and 140 centimetres tall, and thin. She has brown hair and brown eyes.
It is believed she was wearing a pink top with a round-neck collar, a black knee-length skirt and pink Nike thongs.
The multi-agency search has used geo-targeting messaging in the Mount Wilson area.
“Whilst police have grave concerns for her safety, we are thankful the weather has been kind to us over the past few days and we believe the weather would be sufficient for her to be able to survive this time in the bush,” Chief Inspector Garry Sims said on Sunday.
“There’s water in the bush so we are hopeful Charlise will be able to sustain herself until we find her.”
