A drive-by shooting of a home in Sydney's south that could have "easily" killed two innocent men may be a case of mistaken identity, police say.
Officers were called to a house in Connells Point around 9pm on Friday night after neighbours reported hearing gunshots.
They arrived to find the upper storey of the house and a car parked out the front riddled with bullet holes.
Half an hour later a vehicle that was seen in the vicinity of the shooting was found nearby, burned out and with stolen or fake plates.
NSW Police Superintendent Jason Box on Saturday said the two men inside the home at the time of the shooting were lucky to escape uninjured.
"Shooting indiscriminately into a premises in a quiet suburban area is not only a cowardly act, it's also extremely dangerous," he said.
"For the number of shots that were fired into the residence ... it could have quite easily been a fatality for them."
The men don't have any links to crime groups or figures, and police have found no explanation as to why they may have been targeted.
"(The shooters) obviously have planned this to a certain extent, but it would appear that they have made a mistake," Supt Box said.
"There's nothing to suggest that anyone in that street at this point is a target."
Police will maintain a visible presence in the area as detectives continue to comb over the crime scene.
