Police have set up a crime scene where a man was shot in Sydney overnight.

Police are investigating after a man was shot dead in Sydney's west on Friday night.

Emergency services were called on Brisbane street, St Marys, about 7.20pm after reports of shooting in the area, police said.

When they arrived, police found a man in his 30s with gunshot wounds outside a home. He was treated by paramedics but died at the scene.

Police haven't been able to confirm the man's identity.

A crime scene has been established and will be examined by specialist officers.

Channel 9 reports that neighbours heard between 8 to 10 gunshots and that the stricken man was found lying in a gutter.

Witnesses told police that a vehicle drove away from the scene a short time after the shots were heard, according to NewsCorp Australia.

Detectives believe the shooting was targeted and are probing possible links to outlaw motorcycle gang activity.

Police told reporters in Sydney that the man was gunned down by 2 men who were driving a silver Commodore.

Authorities believe the victim was gunned down at "point blank range" with a semi automatic weapon while he was lying in the gutter.

Detective Inspector Grant Taylor said it was too early to tell why the murder took place but that the murdered man was closely associated with outlaw motorcycle gangs.

The two shooters were wearing balaclavas at the time the attack was carried out, he said.

He said the shooting was highly targeted and that locals with no links to criminality had nothing to fear.

There are reports that the man was shot dead in front of his fiancee, who has been described as "very shaken up" by the shocking incident.
