The 27-year-old victim was found with a knife wound at a Quakers Hill house on Wednesday evening. She died at the scene.
"(It) was so severe that she was deceased by the time the police attended," Superintendent Jennifer Scholz told reporters on Thursday.
Her husband, 31, was arrested and taken to Blacktown Hospital for treatment to lacerations on his hands before being returned to custody. He was on Thursday charged with murder and is due to face Parramatta Local Court on Friday.
The couple had moved to Australia from India two years ago.

“Violence is never acceptable and it is such an incredible tragedy that this happened.”
