A loving young woman bashed to death by her boyfriend in her Sydney apartment had no chance of surviving his "insane jealousy" and "utter contempt for women", her mother says.

Rhonda Baker's family broke down in court on Friday, also International Women's Day, as they detailed the profound loss of their daughter, granddaughter, niece, cousin, workmate, aunty and sister.

Onitolosi Etuini Atiai Latu, 30, was found guilty of murdering 26-year-old Rhonda Baker.

The 26-year-old was murdered by Onitolosi Etuini Atiai Latu in Liverpool in August 2016.

Latu's NSW Supreme Court trial heard he had sent emails threatening to "cave" his girlfriend's head in prior to her death.
