Two South Australians and a woman from New South Wales have been charged over online child sex abuse and exploitation material, as part of an investigation involving SA, NSW and Federal Police.
Officers said a 34-year-old man from Adelaide's northern suburbs had been refused bail over alleged possession and dissemination of child exploitation material.
A 32-year-old woman from regional NSW was refused bail and will face court in Taree accused of aggravated sexual assault of a child and dissemination of child abuse material.
A 45-year-old woman from Adelaide's northern suburbs, also denied bail, is facing aggravated offences of production, possession and dissemination of child exploitation material, indecent assault and gross indecency allegations.
Police warned the public that any app, online game or social media platform which allowed people to be in contact with others they did not know could put them at risk.
They urged anyone with information about people involved in online child sexual exploitation or abuse to report the issue to Crime Stoppers on 1800 333 000.
