It is an offence to participate in a criminal organisation:

A criminal organisation means a criminal group or an organisation declared under Part 2 of the Serious and Organised Crime (Control) Act 2008 (SA) [s 83D].

A criminal group is a group of 2 or more people whose aim is to engage in or facilitate conduct that amounts to a serious offence of violence, or a serious offence that would benefit the group [s 83D].

Participating in a criminal organisation carries a maximum penalty of imprisonment for 15 years [s 83E(1)].

It is also an offence to assault someone or damage property knowing, or being reckless as to whether, that act constitutes participating in the criminal activity of a criminal organisation, with a maximum penalty of imprisonment for 20 years [s 83E(2)]. The maximum penalty is 25 years if the person assaulted is a public officer acting in the course of their official duties [s 83E(4)].
