Three women will face court accused of being part of a syndicate helping parents across Australia abduct their children.
The Australian Federal Police has served notices on the trio – aged 75, 68 and 46 – from Taree, Newcastle and Townsville as part of the long-running investigation into the network.
It follows the arrest of three people last month.
It's alleged they helped provide transport, accommodation and other support to allow two mothers to abduct three children in contravention of two family law orders.
All three children were found safe by AFP officers earlier this year.
"The actions of these people in deliberately ignoring court orders and helping hide children from their extended families, the courts and law enforcement cannot be justified," AFP Assistant Commissioner Debbie Platz said in a statement on Monday.
"This activity has the potential to significantly endanger the safety and wellbeing of children."
All three women will be charged with conspiracy to defeat justice, while the 68 and 46-year-olds will also be charged with child stealing.
They will face court next month.
