CCTV captured the gun-wielding man creeping down the side of a house in on Karuah Street, Greenacre, about 1.10am, before firing several shots.
Police found a number of bullet holes in the garage door.
Bankstown Acting Superintendent Darren Sly said it was a targeted attack, however at this stage the motive or reasoning for that shooting was still under investigation.
“A public place shooting and a shooting like this is done by cowards, where they can hide behind a gun,” he said.
Anyone with information about this incident is urged to contact Crime Stoppers: 1800 333 000 or nsw.crimestoppers.com.au. Information is treated in strict confidence.
