Criminal Damage & Arson

Being accused of criminal damage or arson can be overwhelming. These charges are often complex, and even a simple misunderstanding can lead to serious consequences. The difference between an accident and a criminal offence can hinge on fine details such as intention, lawfulness, and cause.

To constitute a criminal offence, the damage must generally be unlawful and, in many cases, intentional or reckless. Penalties range from fines for minor property damage to imprisonment for more serious or deliberate acts. Indeed, the maximum penalty for criminal damage by fire is life imprisonment.

What the Court Considers

When sentencing for property damage or arson, the Court will carefully assess:

  • How the damage occurred — was it deliberate or accidental?
  • The extent of the loss and any steps taken to reduce or repair it;
  • Whether compensation was offered;
  • The surrounding circumstances, including any threats, violence, or domestic dispute;
  • Whether the offender had a mental illness.

Every case is different. Having an experienced criminal defence lawyer in Perth on your side can make all the difference.

Defending Arson and Fire-Related Allegations

Allegations involving fire or arson often raise complex technical questions. Investigators may focus on how the fire started, who was responsible, and whether there was any lawful purpose for ignition — such as a controlled burn.

In recent years, prosecutors have increasingly relied on the Bush Fires Act in cases where the Criminal Code may not apply. However, not every charge under this Act is valid. A person accused of setting fire to their own property has not necessarily committed an offence under the Criminal Code unless there was intent to defraud, such as starting a fire with the intention of making a false insurance claim.

At Perrella Legal, we examine every detail — from forensic fire reports to witness evidence — to expose weaknesses in the prosecution’s case and ensure your rights are protected.

Frequently Asked Questions

“Criminal damage” generally means unlawfully damaging someone else’s property. Arson is a form of criminal damage where the damage is caused by fire or explosion. Arson offences are treated more seriously because of the risk to life and surrounding property.

Not always. Many fire-related offences require proof that the damage was intentional or reckless, not necessarily planned.
A key issue is often whether the fire was a true accident or whether the conduct involved criminal negligence or disregard for obvious risk.

If the fire was genuinely accidental and not caused by unlawful or reckless conduct, you may have a defence.
These cases often turn on technical evidence about how the fire started, and whether your actions meet the legal threshold for criminal responsibility.

Possibly — but not automatically.
Under the Criminal Code (WA), damaging your own property by fire is not usually an offence unless it was unlawful, such as where there is intent to defraud (for example, to knowingly make a false insurance claim).
However, police sometimes pursue charges under the Bush Fires Act, depending on circumstances.

Arson investigations typically involve forensic fire experts, reconstruction of the fire’s origin, witness accounts, and elimination of other possible causes.
Even small errors in early investigation can create major weaknesses in the prosecution case.

Penalties vary widely depending on the facts.
Minor property damage may result in a fine or community order, but criminal damage by fire can carry a maximum penalty of life imprisonment, especially where the fire endangers people or destroys a dwelling.

Courts look closely at:

  • Whether the fire was deliberate, reckless, or accidental;
  • The extent of damage or risk created;
  • Any attempts to limit damage or assist emergency response;
  • Whether compensation was offered;
  • Any threats, violence, or domestic context; and

Your personal circumstances, including mental health.

Depending on the evidence, defences may include:

  • The fire was accidental;
  • You did not start or cause the fire (identity issue);
  • There is insufficient proof of intention or recklessness;
  • The ignition was lawful (e.g., a controlled burn with proper authority); or
  • The investigation is unreliable due to forensic or procedural flaws.

Do not attend an interview or give a statement without legal advice.
Even innocent explanations can be misunderstood or used against you later. Contact Perrella Legal before speaking with investigators.
