In the ACT, sabotage offences are contained in the Criminal Code 2002. These offences involve deliberately causing damage to public facilities in order to disrupt services or functions or cause economic loss. Sabotage is considered one of the most serious criminal offences in Australian law due to its potential impact on national security, public safety, and economic stability. This page deals with sabotage offences in the ACT, including penalties, defences, and the legal process involved in prosecuting these charges.
What is sabotage?
Under section 423 of the Criminal Code 2002, a person is guilty of sabotage if they:
- cause damage to a public facility by committing a property offence or cause an unauthorised computer function; and
- intend to cause major disruption to government functions, major disruption to the use of service by the public or major economic loss.
This is offence is not committed simply by taking part in a strike, action or lockout.
The maximum penalty for sabotage is 25 years imprisonment, a fine of 2,500 penalty units, or both.
Elements of Sabotage
For a successful prosecution of sabotage under the ACT Criminal Code, the prosecution must prove beyond reasonable doubt that the accused intended to cause major disruption or economic loss. The term "major" is significant and requires substantial impact rather than minor inconvenience. Public facilities include government buildings, utilities, transportation systems, telecommunications infrastructure, and other essential services that the public relies upon.
Computer-Related Sabotage
Modern sabotage offences increasingly involve cyber attacks and unauthorised computer functions. This can include hacking into government systems, disrupting digital infrastructure, or damaging computer networks that support public services. The Criminal Code 2002 recognises that contemporary sabotage may not involve physical damage but can be equally destructive through technological means.
Threaten sabotage
Under section 424 of the Criminal Code 2002, a person is guilty of an offence if they threaten to commit sabotage. Threatening sabotage carries a maximum penalty of 15 years imprisonment, a fine of 1,500 penalty units, or both.
A person may be found guilty of this offence even if the person who was threatened did not actually fear that the threat would be carried out.
Nature of Threats
Threats of sabotage can be communicated through various means including verbal statements, written communications, electronic messages, or implied through conduct. The law does not require that the threat be specific or detailed, but it must be credible enough to constitute a genuine threat of sabotage. The prosecution must establish that a reasonable person would interpret the communication as a threat to commit sabotage.
Attempted sabotage
Under section 44 of the Criminal Code 2002, a person can be found guilty of an attempted offence if they attempt to commit an offence by engaging in conduct that is not merely preparatory to the commission of the offence.
A person may be found guilty of attempting to commit sabotage even if the offence they were attempting to commit was impossible to commit, or even if the offence was actually committed.
An attempted offence carries the same maximum penalty as the offence that was attempted. In the case of attempted sabotage, the maximum penalty is 25 years imprisonment, a fine of 2, 500 penalty units, or both.
Conduct Beyond Preparation
The distinction between preparatory conduct and attempted sabotage is crucial in determining criminal liability. Courts examine whether the accused's actions moved beyond mere planning and preparation to actual steps toward committing the offence. This might include acquiring materials for sabotage, conducting surveillance of target facilities, or taking preliminary steps to access restricted areas.
Defences to Sabotage Charges
Several defences may be available to individuals charged with sabotage offences under the ACT Criminal Code. Understanding these potential defences is crucial for anyone facing such serious allegations.
Lack of Intent
The prosecution must prove specific intent to cause major disruption to government functions, public services, or economic loss. If the accused's actions were accidental, reckless, or intended for a different purpose, this may provide a defence. The defendant may argue that any damage caused was unintentional or that they did not foresee the consequences of their actions.
Legitimate Protest Activity
Section 423 specifically excludes participation in strikes, industrial action, or lockouts from constituting sabotage. This protection extends to lawful protest activities and civil disobedience that falls within constitutional rights to freedom of expression and assembly. However, this defence does not cover actions that go beyond legitimate protest and cause actual damage to public facilities.
Investigation and Prosecution Process
Sabotage investigations in the ACT typically involve multiple law enforcement agencies due to the serious nature of these offences and their potential impact on national security and public safety.
Law Enforcement Response
The Australian Federal Police (AFP) often takes the lead role in sabotage investigations, particularly when they involve critical infrastructure or have national security implications. ACT Policing may also be involved, especially for locally-focused incidents. These investigations often involve extensive forensic analysis, surveillance, and intelligence gathering to establish the full scope of any sabotage plot.
Evidence Collection
Prosecutors must gather substantial evidence to prove sabotage charges beyond reasonable doubt. This includes physical evidence of damage, expert testimony about the impact on public services, digital forensics for computer-related sabotage, and evidence of the accused's intent. The complexity of these cases often requires extensive preparation and expert witnesses to explain technical aspects to the court.
Jurisdiction
Sabotage offences are strictly indictable offences and can only be finalised in the ACT Supreme Court. A person facing one of these charges will have to go through a committal proceeding in front of a magistrate before the matter may be transferred to the Supreme Court.
Committal Proceedings
During committal proceedings, the magistrate determines whether there is sufficient evidence to warrant a trial in the Supreme Court. This process allows the defence to examine the prosecution's case and may result in charges being dismissed if the evidence is insufficient. The committal hearing also provides an opportunity for plea negotiations and case management directions.

Frequently Asked Questions
What counts as a 'public facility' for the purposes of sabotage offences in the ACT?
Public facilities include government buildings, utilities, transportation systems, telecommunications infrastructure, and other essential services that the public relies upon. The definition is broad and covers any facility whose disruption would have a major impact on government functions or public services. The key element is that the damage must be intended to cause major disruption or substantial economic loss, not merely minor inconvenience to a service or facility.
How does the ACT Criminal Code treat cyber attacks as sabotage offences?
The ACT Criminal Code 2002 specifically recognises computer-related sabotage as a serious offence. Causing an unauthorised computer function that results in major disruption to government operations, public services, or significant economic loss can constitute sabotage. This includes hacking government systems, disrupting digital infrastructure, or damaging computer networks supporting essential public services. Cyber sabotage carries the same maximum penalty of 25 years imprisonment as physical sabotage, reflecting its equally destructive potential.
