Investigators believe two men on a motorcycle stopped on McAdam Street and fired a single shot towards property on Blyth Street just before 7:30am on 14 March.
The bullet struck a car parked in the carport of the residence.
Although the car was unoccupied, six people were home at the time, including a 31-year-old man, a 35-year-old woman, and four children aged 18, 13, nine and one.
Police believe the two men then fled on the bike along McAdam Street at a fast rate of speed.
Investigators have released CCTV of a motorcycle and two men who they believe can assist with their enquiries.
Both offenders are believed to be male, the rider was wearing a helmet, but the passenger was not.
Both were wearing dark clothing on top and light clothing on the bottom.
