Warning: This article contains details of alleged child sexual abuse which may be distressing to some readers.

More than 1,200 children are being urged to undergo precautionary health screening after a former childcare worker was charged with more than 70 offences relating to alleged child sexual abuse at a centre in Melbourne’s south-west.

Joshua Dale Brown, 26, from Point Cook, has been charged over alleged sexual offences against eight children – aged between five months and two years – at the Creative Garden Early Learning Centre in Point Cook, where he worked between April 2022 and January 2023.

Victoria Police revealed Brown has worked at 20 childcare centres between 2017 and 2025, with investigations ongoing and additional allegations, including one involving a centre in Essendon, being pursued.

Deputy Commissioner Wendy Steendam said the case is “incredibly distressing”, describing the allegations as confronting and involving “some of our most vulnerable people in our community”.

The charges laid against Brown include sexual penetration of a child, producing child abuse material, and recklessly contaminating goods to cause alarm or anxiety.

Detectives from the Sexual Crimes Squad began investigating in May after they allegedly uncovered child abuse material and executed a search warrant at Brown’s Point Cook home. He had not previously been known to police and held a valid Working with Children Check at the time of his employment.

Police said the families of the eight alleged victims were notified last week.

“As you can imagine, this was deeply distressing for the families to hear,” said Acting Commander Janet Stevenson, adding that not all centres where Brown worked are believed to be connected to the alleged offences.

In a coordinated response, Victoria Police and the Department of Health have contacted more than 2,600 families whose children may have been at centres during Brown’s employment. About 1,200 children have been recommended for infectious disease testing “out of an abundance of caution”, authorities said.

Chief Health Officer Dr Christian McGrath said while the public health risk is low, the testing was being recommended due to a potential exposure risk during the relevant period.

“We do understand this is another distressing element to the situation and we’re taking this approach as a precaution,” Dr McGrath said, assuring families that any infections could be treated with antibiotics and that there is no broader risk to the public.

Letters sent to families on Tuesday stated: “At this stage, there is no evidence to suggest that your child has been offended against. If this changes, you will be contacted directly by Victoria Police.”

Support lines staffed by professionals have been established, and the government has promised free testing and assistance for affected families.

G8 Education, the operator of the Point Cook centre, said it was “extremely distressed” by the allegations and is fully cooperating with authorities. In a statement, the company said all legally required employment and background checks were carried out during Brown’s employment.

“G8 Education has no tolerance for any behaviour that compromises the safety or wellbeing of children,” the company said.

Brown has been remanded in custody and is scheduled to appear at Melbourne Magistrates Court in September.

The investigation remains ongoing.
