Self defence in QLD is a real defence, not a plea for sympathy, and there is one thing about it worth knowing before anything else.

Once self defence is properly raised on the evidence, you do not have to prove you were defending yourself. The directions Queensland Courts publishes for judges to give juries put it plainly: the burden remains on the prosecution at all times to prove that the defendant was not acting in self defence, and to prove it beyond reasonable doubt.

That is the opposite of what most people assume when they are sitting in a watch house convinced they have to somehow prove their innocence. It does not mean the defence succeeds, and nobody can tell you whether it would in your matter. It does mean the work is not all on your side of the table.

What the law allows you to do

The starting point is the ordinary situation. Someone attacks you and you did not provoke it.

In that situation the Criminal Code allows you to use the force that is reasonably necessary to defend yourself effectively, as long as the force is not intended to cause death or grievous bodily harm and is not the kind of force likely to cause it.

Two words in that are doing all the work.

Reasonably. Not the force you wished you had used afterwards, and not the force a calm person might have chosen with time to think. What was reasonably necessary in the circumstances as they actually were.

Necessary. Force used after the threat has ended is a different thing from force used to meet it. This is where a lot of otherwise good self defence arguments run into trouble, because of what happened in the few seconds after the other person stopped.

One thing worth clearing up, because people arrive expecting it. Proportionality and imminence are not separate boxes that have to be ticked before self defence is available. They sit inside the assessment of what was reasonably necessary, which is how the Queensland Courts jury directions treat them. So the question is not whether your response passed a proportionality test. It is whether, in the circumstances as they were, the force you used was reasonably necessary.

The line at serious injury

There is a separate and higher rule for the worst situations.

Where the attack on you is such that you have a reasonable apprehension of death or grievous bodily harm, and you believe on reasonable grounds that you cannot otherwise preserve yourself, the Criminal Code allows force that would otherwise be beyond the limit, including force likely to cause death or grievous bodily harm.

That is a genuinely different test, and it is not reached just because a fight felt frightening. It turns on a reasonable apprehension of death or really serious injury, and on there being no other way out that you reasonably believed was open to you.

If you started it, or provoked it

Harder, but not automatically gone.

Where you unlawfully assaulted the other person first, or provoked the assault, the Criminal Code has a separate and narrower rule. Self defence is available only where the other person responds with such violence as to cause a reasonable apprehension of death or grievous bodily harm.

And it is excluded altogether where you began the assault intending to kill or to do grievous bodily harm.

So a scuffle you started, which the other person escalated dramatically, is not necessarily outside self defence. A fight you started intending to seriously hurt someone is.

This distinction matters more than almost anything else in a pub fight case, and it is exactly the sort of thing where the sequence of events, second by second, decides the outcome.

Defending someone else

The Criminal Code extends the same protection to a person acting in good faith to defend someone else, using a like degree of force to that which the person being defended could lawfully have used.

That is worth knowing, because a great many charges come out of somebody stepping in to help a mate, a partner or a stranger. Stepping in is not automatically unlawful. What was reasonably necessary is still the question.

Defending property

There are separate provisions again dealing with force used to defend a dwelling and property. They are not the same rules as personal self defence and they should not be assumed to work the same way.

If your situation is about someone coming into your home or onto your land, that is a specific question worth asking about rather than reasoning across from what you have read about defending yourself.

Why "he swung first" is a beginning, not an end

People arrive convinced that because the other person threw the first punch, the matter should be over. It is a very good starting fact and it is not the whole analysis.

The questions that follow are the ones that decide these cases. Was the force you used proportionate to what you were facing. Did it stop when the threat stopped. Was there a way out you reasonably believed was available. Is the account you gave police consistent with the injuries, the footage and what the witnesses say.

None of that is a technicality. It is the substance of the work.

What evidence actually matters

Footage. Pubs, car parks, servos and buses are covered by cameras, and footage is routinely overwritten within days or weeks. If it exists, somebody needs to ask for it now rather than in three months.

Your injuries. Photograph them, and see a doctor. An injury nobody documented is very hard to prove later, and your injuries are often the clearest evidence of what you were facing.

Witnesses. Get names and numbers while people are still contactable. In a town where a lot of work is seasonal, witnesses move on quickly.

What you said to police. This one cuts both ways and it is the reason to be careful. A rushed account given at the roadside or in a watch house, before you have slept, can lock you into a version that does not match what the footage later shows. You are not obliged to talk your way out of it on the spot.

What to do, and what not to

Get advice before you give a detailed account. Wanting to explain yourself is the most natural reaction there is, and it is also how people damage a good defence.

Write down your own sequence of events while it is fresh, for your lawyer rather than for anyone else.

Do not contact the other person. Not to apologise, not to explain, not to check they are alright. It creates a second problem and it can be read in ways you would not intend.

And get the QP9, which is the police version of what happened, because self defence is argued against what the prosecution says it can prove, not against what you remember.

This article is current as at August 2026 and states the law as it stands. These defences are under review, though. The Queensland Law Reform Commission delivered 36 reform recommendations to the Attorney-General on 1 December 2025, including changes affecting victim-survivors of domestic violence. Nothing in this article has changed as a result, but if reform is enacted the position will move, so check the current material rather than relying on an article.

If you were defending yourself and you have still been charged

Being charged when you believe you were the one being attacked is a particular kind of unfair, and it happens regularly, usually because police arrive after the event and take the account of whoever was still standing and talking.

That is not the end of it. What matters now is getting the evidence secured while it still exists and getting your account into a form that holds up.

We act in assault and violence matters in Cairns and across Far North Queensland, including matters where self defence is raised. If you have been charged after defending yourself, the useful work here is time sensitive.

If you have been charged after defending yourself in Cairns, speak with us early, because footage and witnesses do not stay available for long.
