Dozens of people have been arrested following days of raids targeting the alleged creator and users of a secret app for criminal communications.
Around 700 Australian federal police members were involved in more than 70 searches around the nation this week, leading to the arrest of 38 people.
The raids also took down a global encrypted communications network, the AFP said.
A man police will allege created and maintained the network was due to face court on Wednesday.
Encrypted communication networks, including some reliant on dedicated devices, have become a focus for law enforcement targeting transnational organised crime.
The AFP and the US FBI previously ran a platform to gather evidence on murder plots, drug importations and weapon purchases which were openly discussed on the network because criminals thought it was secure.
It was exposed as being part of a law enforcement operation in 2021.
