Neighbours who live by the back fence of the Masjid Al Noor on Deans Ave offered shelter to dozens of people who managed to escape from the mosque after the shooting started on Friday.
Jason, a neighbour who only wanted to give his first name, told the Herald that he saw dozens of people leap over his 2m-high fence in a panic and then sprint down the driveway, away from the shooting.
He opened his front door to offer refuge, and about 10 people ran inside, he said.
"There were lots of people climbing over the fence here and then got help here."
He said they stayed for several minutes before police arrived at the scene.
