Detectives have set up a command centre in Townsville as they ramp up investigations into the suspected murder of a 47-year-old woman at her home in North Queensland.

Officers discovered the 47-year-old's body at a unit on Chander Street in the Townsville suburb of Garbutt nearly two weeks ago, on November 4, but believe she had been dead for days.

A police spokesperson said the woman had died about the end of last month.

"Investigations to date have indicated a significant incident which resulted in the woman's death occurred around October 30," the spokesperson said.

Her body was discovered after an anonymous caller asked them to make a welfare check.

The woman’s death is the third violent death of a woman in the Townsville policing district within two months.

A spokesman for police said "significant resources" had now been allocated to the homicide investigation, in a bid to find who was responsible.

"A command centre has been established in Townsville and significant resources have been allocated to investigate all possible circumstances leading up to the incident and to locate and arrest the person or persons involved and provide answers for the family," they said.

Officers are particularly interested in any vision from businesses or residences on more than a dozen Townsville streets on October 31, that captures a person walking on the road or pathways.
