A woman found dead in her Picton home on Sunday afternoon has been named as 43-year-old Robyn Alma Grace.
Police were called to a disturbance at the house about 4:30pm, and an officer who entered the house found the woman dead.
Detective Inspector Geoff Jago said two other people inside the house at the time were taken into custody and handcuffed by the officer without incident.
Both have been charged with Ms Grace's murder.
A post-mortem carried out on Tuesday has established how she was killed, but police will not release that information.
Police are continuing a scene examination at Ms Grace's home and interviewing nearby residents.
