A fence had been pulled to the ground, pot plants broken and small trees trampled.
Shocked neighbours said they woke in the middle of the night to grunty car noises.
"I heard the bottles smashing and they did burnouts, then they took off down the road," Sean Taylor, 23, said.
Another neighbour thought it was a group of drunk teenagers until he heard abuse and shouting. "There was definitely two cars."
Taylor said he heard the two cars go down nearby Bayswater Ave.
He said Charnley and her children had only recently moved back with her father, who was unwell. Charnley's mother said the family were coping with the allegations and the abuse.
"Everyone is innocent until proven guilty," she said. "We are coping - just."
Jerome Kino, the owner of the stolen Mitsubishi, said he was not involved in the attack, though he had received a threatening phone call about 3pm yesterday.
"I got threatened for my house getting smashed up," Kino said.
"They said 'We at your house now, if you don't come down now we will eff it up.' It is probably seen as suspicious but I was not there. I was with my two mates and they will back that up ... I'm willing to help find out who it was."
North Shore Area Commander Les Paterson said the police were investigating.
