Neighbours who declined to be named for fear of retribution, say they have been verbally abused daily, robbed and had their homes and cars vandalised since the home for adolescents was established in the suburb five years ago.

Residents consistently reported what appeared to be a lack of supervision, with multiple neighbours alleging they found no carers at the house on multiple occasions.

"My concern is they're not being looked after to the degree they need," a resident said.

"I've gone around a few times to complain but there's no carers present."

The Mercury obtained photos depicting children in the care of the facility playing unattended on the roof of the property.

CareSouth told the Mercury the home in question had around-the-clock supervision and urged any neighbours with concerns to make contact to resolve any issues they had.

"Young people sometimes engage in risk-taking behaviour," said CareSouth chief executive Debra Tozer.

"Whilst I have stated previously that I cannot comment on specific events involving young people in statutory out-of-home care for privacy reasons, I can assure you that CareSouth has policies and procedures in place for the reporting of incidents."

During one serious incident, one neighbour alleged the carer in charge was intoxicated.

In 2012, one resident and his partner heard female screams coming from the road and went out to assist.

"I took the south end of the road and my partner took the north end to divert traffic until the ambulance and police arrived ... all hell broke loose."

According to the resident involved, the carer responsible for supervising the teen involved appeared intoxicated: "I had the impression she was drunk - she had slurred speech and was sitting on the street not helping, her head in her hands."

Neighbours have approached the facility's managers in the past to resolve issues but found results to be mixed due staff turnover.

"I went over there to have a cup of tea with one manager when it first opened and he listened to us and did things like telling staff to park on the lawn instead of on the street, but he left ages ago," one said.

"We complained about them being on the roof and throwing fruit at my wife, but most of the time we're told to call the police because the carers aren't allowed to touch the kids," another said.

One neighbour wrote a letter that went unanswered after counting 58 "go f-yourselves" and "about 30 c-words" heard in one conversation in the street between the care facility's children.

"These kids are mostly underage and most roam the streets between 10pm and two in the morning, causing havoc," said the neighbour.

"I've broken out in a stress rash after one of the girls abused me after asking her not to swear in front of my grandchildren," one neighbour said.

One one occasion, cars were damaged after neighbours complained to CareSouth carers at the property, the residents alleged.

"They target neighbours who complain, cars were egged and damaged," a resident said.

The Department of Family and Community confirmed CareSouth would receive more than $13 million in funding in 2014-15 for the provision of up to 230 out-of-home-care placements.
