A drive-by shooting at a bikie clubhouse has been caught on CCTV footage, with an unmarked police car also shot at moments later.

Police say it was "only luck" that police officers and other people in the area of the public escaped unscathed from the "extremely concerning" incident at the Outlaws Motorcycle Clubhouse in Carrum Downs, outer south-east Melbourne, on September 27 last year.

Police have released CCTV in a public appeal for information, months after what's believed to be a targeted attack.

Police say shots were fired at a group of people outside the Titan Drive property, from a dark-coloured SUV that drove past around 7.45pm.
