Police have admitted they could have done more to help a woman before she was stabbed by her son.
An Independent Police Conduct Authority report found the police underestimated the woman's situation from her first two 111 calls and failed to send officers.
She was then stabbed in the back by her son, who was later found to be insane.
Police communications centre national manager Superintendent Dave Trappitt said they should have acted with greater urgency and not delayed their response.
"We also share the IPCA's view that if Police had attended the address sooner, the stabbing may have been avoided," he said.
"Police have sincerely apologised to the victim for the way in which we responded to her calls."
