“She's got horrific scars across her neck,” Marley’s mother Gail told 9News.
“She's been having nightmares since it happened.”
Since the incident occurred last Thursday - the second hat cord related injury in the past two weeks - Australia's Department for Education and Child Development has issued a Hazard Alert.
“Ensure hats and clothing do not have chin straps, cords, drawstrings, toggles and hooded clothing has no draw strings,” the alert read.
Parents who want more information have been advised to contact their school principals.
