A mum and her three kids have survived a scary shooting incident where projectiles were fired into their home in Kurri Kurri.
The woman woke early Sunday after hearing a motorbike going up and down Greta Street several times.
Police say she then heard a loud noise and discovered a hole in a front window.
Holes were also found in the lounge room and a kitchen window, and in the driver's door of her car.
Three people were later arrested in a car spotted driving erratically nearby.
A gun and ammo were allegedly found inside.
However police say the two 22 year old men and 18 year old woman are not responsible for the initial shooting.
