They found 21-year-old Nunia Kurualeba with two stab wounds to her chest and other "significant injuries" at the Great Western Highway property, Detective Superintendent Trent King said.

She was treated by paramedics but died at the scene.

Jeremaia Tuwai, 21, was arrested without incident in Penrith on Monday evening after allegedly being spotted running away from the property.

Police said the two had been in a domestic relationship.

Mr Tuwai was charged on Tuesday morning with domestic violence murder.

He did not apply for bail and his matter was adjourned to September 6.

Neither Mr Tuwai or Ms Kurualeba had prior contact with the police over domestic violence issues, police said yesterday.

A friend of the Ms Kurualeba, Sokoveti Nayacakalou, was at home when she heard about what had happened.

"Her sister called, crying and telling me about the news," she said.

"We were shocked."

Ms Nayacakalou said the alleged victim was a "loving person" who enjoyed "making people laugh".

"She's just a happy person. She didn't deserve any of this," she said.
