Detective Inspector David Harbison said the woman had been shot at by two men with investigators treating the matter as a homicide.
"Early investigations indicate the deceased was assaulted by two male persons who may have chased her down Railway Parade," he told reporters on Sunday.
"Police are investigating reports of up to three to four shots fired in that street."
During the assault the woman is believed to have received a gunshot wound.
Det Insp Harbison said police do not believe the incident was a random attack.
A number of witnesses are currently assisting police with no clear suspects on police radar.
"It was very dark... two males is about all we've got at the moment," Det Insp Harbison said.
"I want to reassure the public that a dedicated task force of local detectives along with specialist homicide detectives have been deployed to investigate this crime, the goal will be to bring the persons responsible to justice as quickly as possible," he added.
