You are in a situation that is escalating quickly. Someone is threatening you, moving into your personal space, or perhaps they have already put their hands on you. Your brain switches to survival mode. You push them back. You might throw a punch or grab something nearby to protect yourself. In that moment, it feels like you have no choice.
Then the police arrive. Suddenly, you are the one being questioned.
Witnesses saw you hit someone, and there is evidence of an injury. You try to explain that you were scared and reacting to a threat, but the officer simply takes notes and tells you that you are being charged with assault.
It is a confusing and frustrating position to be in. How does protecting yourself become a criminal offence? Usually, it comes down to the gap between what we think self-defence means and how Western Australian law actually defines it. We’ve recently had a chat with the guys at Podmore Legal and according to them, this is one of the most misunderstood areas of criminal law. Many people genuinely believe they acted within their rights, only to find out later that their actions did not meet the legal criteria.
The Legal Definition of Self-Defence in WA
In Western Australia, self-defence is covered by Section 248 of the Criminal Code. While the law admits that you have a right to protect yourself, that right has very specific boundaries.
For your actions to be considered lawful, three things generally need to be true:
You must have believed your actions were necessary to defend yourself or someone else.
That belief must have been reasonable.
The force you used must have been proportionate to the threat.
These requirements have layers that often trip people up. What feels “reasonable” when your adrenaline is pumping might not look reasonable to a magistrate sitting in a quiet courtroom months later.
There is also a major distinction between defending yourself from an active attack and responding to one that has already ended. Self-defence is about protection, not getting even. If someone punches you and then stops, hitting them back is usually seen as retaliation, which is a crime.

Common Misconceptions
A lot of people think that if someone starts a fight, they have a “free pass” to do whatever it takes to win. That is not the case.
Another common myth is the idea of “standing your ground.” While WA law does not strictly require you to run away before you can defend yourself, a court will definitely look at whether you had an easy way to avoid the violence but chose not to take it.
Pre-emptive strikes are another grey area. You might feel justified striking first if you think someone is about to hit you, but the law is wary of this. You would need to prove you had solid grounds to believe an attack was imminent and that you had no other choice. Simply hitting someone because they look aggressive or because an argument is getting heated is rarely enough to stand up in court.
The Proportionality Question
This is where most self-defence claims fall apart. Your response has to “fit” the threat.
If someone pushes you and you respond by pulling a knife, that is not proportionate. If someone threatens a punch and you hit them with a heavy object, you are likely heading for an assault charge. The court looks at what you knew at the time, but your perception has to be grounded in reality. If there was no reason to think someone had a weapon, claiming you “thought they did” won’t carry much weight.
Once the threat stops, your right to use force stops too. If you keep hitting someone after they have fallen to the ground or stopped fighting, you have moved from self-defence into assault.
Defending Others and Property
You are allowed to use force to protect someone else, provided you follow the same rules of necessity and proportionality. However, this is risky because you are acting on your perception of someone else’s fight. If you jump into a scuffle and end up hitting a plain-clothes police officer making a lawful arrest, your “defence of others” claim will be very difficult to prove.
Protecting your property is different. The law allows for some force, but it is much more limited. You generally cannot use serious physical violence just to stop someone from keying your car or stealing a phone.
There is also a common belief that you can do whatever is necessary to an intruder in your home. While the law gives more leeway to people in their own homes, it still isn’t a blank cheque. If you chase a burglar down the street and beat them, that isn’t defence, it’s an assault.
The Problem with Raising Self-Defence Too Early
Many people make the mistake of claiming self-defence the moment they talk to the police. It feels natural to explain why you did what you did, but this can be a massive tactical error.
When you say “I acted in self-defence,” you are admitting you committed the physical act. You are saying, “Yes, I hit him.” If your legal argument for self-defence fails later on, you have already handed the prosecution a confession to the physical part of the assault.
It is often better to stay silent until you have seen the evidence, such as CCTV or witness statements. Blabbing in the back of a police car before you know exactly what you are being accused of can limit your options later.

How Claims Are Assessed
In court, the prosecution does not necessarily have to “disprove” your self-defence claim. Instead, if you raise it, the court looks at whether there is a reasonable possibility that you were acting lawfully. If that possibility exists, you should be acquitted.
However, the court will look at everything:
CCTV footage: Did you have a chance to walk away?
Medical reports: Are the injuries consistent with a “defensive” move?
Credibility: Does your story match what the witnesses saw?
If your version of events contradicts the video evidence or seems exaggerated, the court might decide your fear wasn’t genuine or reasonable.
Alternatives and Retaliation
The law expects you to consider other options if they are available. If you could have safely locked yourself in a car, called for help, or simply walked away, the court will ask why violence was the chosen path. This is especially true in public places like pubs or car parks.
We also need to look closely at the “Retaliation vs. Defence” split. Retaliation feels like justice in the moment, but legally it is just another assault. If there is a pause in the fight (even a short one) and then you go back for more, you have likely lost the protection of a self-defence claim.
When the Claim Backfires
Insisting on a self-defence claim when the evidence is stacked against you can actually make things worse. If CCTV shows you were the aggressor, claiming you were “scared for your life” can make you look dishonest to the judge.
In some cases, a different strategy is better. Maybe the prosecution simply cannot prove it was you, or maybe there is a different legal argument, like provocation or accident, that fits the facts better.
Seeking Help
If you have been involved in a fight and believe you were defending yourself, the smartest move is to get advice before you make a formal statement. You are entitled to a lawyer and you are entitled to time to think.
The team at Podmore Legal has handled many cases where self-defence was the core issue, and they also act as bail lawyers in Perth for those who need immediate help securing release after an arrest. They can help you look at the evidence and decide if a self-defence claim is your best way forward, or whether another strategy is needed to protect your future.
