Man charged over woman's very violent murder

The partner of a young mother has been charged with her domestic violence-related murder.

Police found the 31-year-old Sydney woman's body on Wednesday after a relative raised concerns about her welfare.

Officers broke into her home in Belmore, in the western suburbs, to find she had been the victim of a "very violent murder".

NSW Police have charged a man, 35, with domestic violence-related murder, contravening an apprehended domestic violence order, using a prohibited weapon contrary to a prohibition order and failing to comply with a digital evidence access order direction.

He is due to appear in Campbelltown Local Court on Thursday.

The woman is yet to be formally identified, police said.

Some 73 women have died due to domestic violence in Australia this year, according to community group Destroy the Joint.

Of those deaths, 23 have been in NSW.
