Like the AFP, it too is taking a hard line on hacktivist groups -- part of a threat list which includes individuals, organised criminal syndicates, and "state-based adversaries".

"The Government is aware of recent public debate about whether these actions are a legitimate form of protest activity. However, the Government does not consider 'hacktivisim' or other similar activity that disrupts the confidentiality, integrity or availability of electronic information to be a legitimate form of protest," a department spokesperson said.

"Individuals who become involved in these types of cyber activities need to be aware that they may be committing a criminal offence."
