A 10-year-old girl was found with her throat slit and words carved into her body before her 14-year-old cousin was arrested.
The girl's aunt returned to the family farmhouse in Gunnedah in north-west NSW about 7am on Wednesday to find the girl with blood pouring from her body.
By the time police arrived the girl had already died as a result of multiple knife wounds to her neck and face.
The teenager's mother left the house at about 6.30am with another child to complete farm duties before returning after 30 minutes, The Daily Telegraph reported.
She returned to the farmhouse to find her niece with her throat slit and her daughter missing.
A desperate search for the 14-year-old found her on a neighbouring property at 8.30am.
The girl allegedly told police that she had cut her cousin's throat and stabbed her multiple times with the knife.
Her mother told officers she left both the 14-year-old and 10-year-old asleep but found the younger girl bleeding profusely when she returned.
The 10-year-old had travelled 350km from Orange to stay with her 14-year-old cousin during the school holidays before her death on Wednesday morning.
It is believed the young girl's injuries had been inflicted with a knife and words were carved into her skin, but police are not releasing details of the wounds.
The teenager was arrested and taken to Gunnedah Police Station where she spent the day with medical experts and local detectives.
Forensic police spent much of Wednesday scouring the property for evidence but are believed to remain there over the coming days.
The 14-year-old girl is being held at Gunnedah Police Station but no charges have been laid.
Gunnedah Mayor Councillor Jamie Chaffery told Daily Mail Australia the community's heartfelt prayers were with the family.
'They're dealing with this devastation of losing a young member of the family,' he said.
'The community has been through so much through three years of drought and COVID-19 but we are resilient and supportive of each other to get through the tough times.'
Councillor Chaffery said the community will be devastated by the 'tragic event'.
'We will be there to support each other and we will support the family,' he said.
Those members of our community that will need support, we encourage them to reach out to Lifeline or Headspace.'
'We appreciate the thoughts of the people reaching out from the broad areas across NSW that are offering their thoughts and prayers.'
The family of the 14-year-old have lived at the property more than a decade ago and are said to be well-respected in the Gunnedah community.
Senior police have described the death as one of the worst murders in recent history involving young girls.
