Police were called to a home on Wilpena Terrace in Kilkenny just before 5am on Sunday, almost three hours after the shooting is believed to have occurred. No one was injured.
Officers said two suspects got out of a vehicle parked on nearby Myponga Terrace, walked towards the home and fired at its brick facade before running back to the vehicle and fleeing. The movements were captured on CCTV.
Occupants were inside the home at the time but were unaware of the shooting, police said. A crime scene was established after officers were alerted.
During the investigation, police allege they found weapons inside the property, including a machete and a hunting knife. An 18-year-old man who lived at the home was arrested and charged with breaching a weapons prohibition order.
The search for the two suspected gunmen is continuing.
