Jess JohnsonWhen a gunman opened fire at an In-N-Out Burger in Twin Falls, Idaho on 1 August 2026, an armed bystander widely identified as Jordan Salinas did something that sparked global debate: he returned fire, disrupting the attacker long enough for dozens of diners to escape. Three people died and seven were wounded before the shooter — who later died nearby — was driven from the scene. Witness Lane Koehn told media that Salinas' intervention likely saved additional lives by diverting the gunman's attention at a critical moment. The footage spread quickly across Australian social media, prompting a question few people ever expect to have to answer: if this happened in Sydney, Melbourne, or Brisbane, what does Australian law say about stepping in?
The Question Australians Are Actually Asking
The Twin Falls shooting is among the most widely shared violent incidents on Australian social media in recent weeks, and the debate it has sparked goes beyond the usual gun culture comparisons. Thousands of comments zero in on one core legal question: could a civilian in Australia lawfully do what Jordan Salinas did?
The honest answer is more nuanced than either "yes, be a hero" or "no, stay out of it." Australia does recognise a civilian's right to use force in defence of themselves and others — but it attaches conditions that carry serious criminal consequences if they are misread or exceeded. Understanding those conditions before you are ever in that situation is not paranoia; it is basic legal self-awareness.
What Australian Self-Defence Law Actually Says
Self-defence is a statutory defence available in every Australian jurisdiction. In New South Wales, the key provision is section 418 of the Crimes Act 1900, which states that a person is not criminally responsible for an offence if the conduct was carried out in self-defence. Equivalent provisions exist under section 271 of the Queensland Criminal Code Act 1899 and parallel legislation in Victoria, South Australia, and Western Australia.
The legal test has two limbs that must both be satisfied:
Belief limb: Did the person genuinely and honestly believe their actions were necessary to defend themselves or another person from imminent unlawful violence?
Proportionality limb: Was the force used proportionate to the threat as it appeared to the person at the time — not as an objective observer would later assess it?
Critically, Australian law permits civilians to use defensive force to protect other people, not only themselves. You do not need to know the victim personally. If you witness a stranger being attacked on a train platform in Brisbane or a shopping centre car park in Perth, the legal framework supports intervention — within the proportionality limits outlined in the SA Law Handbook on self-defence, which reflects principles broadly consistent across Australian states and territories.
What the law does not permit:
- Using lethal or near-lethal force in response to a non-lethal or retreating threat
- Continuing to apply force after the attack has ended and the danger has passed
- Using a firearm to intervene, unless you hold a valid firearms licence authorising possession in that location
The Firearms Gap: Why Australia Is Not Idaho
This is where the Jordan Salinas scenario diverges sharply from anything a civilian could lawfully replicate in Australia.
In Idaho, adults can legally carry a concealed firearm without a licence or permit. Salinas — if police confirm his role, which they have not yet done officially — was within the law when he drew his weapon and returned fire at the attacker.
In Australia, civilian firearm ownership is among the most tightly regulated in the world, fundamentally shaped by the 1996 National Firearms Agreement following the Port Arthur massacre. Carrying a concealed handgun in a shopping centre in New South Wales, Queensland, or Victoria is a serious criminal offence regardless of intent — attracting penalties of up to 14 years' imprisonment in some states for unauthorised possession of a prohibited firearm.
That does not mean Australians are defenceless in a violent public emergency. It means the tools available are different: an improvised object used as a shield or barrier, physical intervention to restrain or disarm, or creating escape routes for others — but only to the degree the threat demands, and stopping the moment the threat ends.
If You Were Jordan Salinas in Parramatta: A Concrete Scenario
Consider a realistic Australian equivalent.
It is 12:30 pm on a Tuesday at a food court in Parramatta, western Sydney. A man enters and begins attacking customers and staff with a large kitchen knife, injuring three people in under a minute. You are a 38-year-old construction supervisor with no weapons on you. You have a choice: flee, shelter in place, or intervene.
If you grab a metal chair and use it to block and disarm the attacker, fracturing his wrist in the process:
Under section 418 of the Crimes Act 1900 (NSW), self-defence requires: (1) an honest belief the force was necessary to prevent death or grievous bodily harm to others, and (2) force that is not grossly disproportionate to the threat. A fractured wrist stopping a knife attack in progress almost certainly satisfies both limbs. Courts and juries in comparable NSW and Victorian cases have consistently acquitted civilians who intervened proportionately against active lethal threats.
The legal exposure shifts dramatically in two scenarios:
If you continue striking the attacker after he drops the knife: The threat has ended. Additional force is no longer defensive — it becomes assault. Under NSW law, assault causing grievous bodily harm carries a maximum penalty of 7 years' imprisonment. The self-defence shield protects intervention; it does not protect punishment.
If you were carrying a prohibited weapon (such as a flick knife) and used it: Even if the self-defence of others argument succeeds on the stabbing charge, you face a separate, standalone charge under the Weapons Prohibition Act 1998 (NSW) — carrying penalties of up to 2 years' imprisonment for possession alone. Two separate legal proceedings can run concurrently, even if the first ends in acquittal.
The if/then logic the law applies is precise: if the threat is active and your force is proportionate to the level of danger → you are very likely protected. If the threat has ended or your force exceeds what the situation required → prosecution is likely, regardless of your intentions.
Civil Liability: Good Samaritan Protection
Australians who intervene in emergencies benefit from civil liability protection under Good Samaritan legislation that exists across every state and territory. In NSW, the Civil Liability Act 2002 protects a person who assists someone in an emergency in good faith from civil damages — provided they did not cause the emergency and did not act with gross negligence.
In practice, this means that if a bystander intervenes in a violent attack and the attacker later pursues civil action for injuries sustained during the intervention, Good Samaritan protections are likely to shield the bystander from a damages award. These provisions operate separately from criminal self-defence law. They do not affect whether a charge is laid; they only affect civil liability.
The result is that Australia's legal system, taken as a whole, does provide meaningful protection to civilians who act proportionately in genuine emergencies — but that protection is conditional, jurisdiction-specific, and requires professional legal analysis in any real incident.
Why This Story Matters Beyond the Headlines
The debate around Jordan Salinas resonates in Australia not because Australians could or should replicate his exact actions — the legal and practical context differs fundamentally — but because it surfaces a question that most people have never had to think through: what are your actual rights if you witness extreme violence in a public space?
The answer: you have the right to act to protect others using proportionate force. You have no legal obligation to act. And you face serious criminal risk if your force exceeds the threat, extends beyond it, or involves a weapon you had no lawful authority to carry.
Australian law is calibrated carefully here: it rewards protection, not vigilantism. It gives civilians legal cover to act in the moment — but demands they stop the instant the danger passes.

What to Do After Any Violent Incident
If you have been involved in a violent public incident — as a victim, a bystander who intervened, or someone whose actions are now under scrutiny — the first step before making any statement to police is to consult a criminal defence lawyer.
Statements made at the scene, however well-intentioned, can be used as evidence in subsequent proceedings. A lawyer can advise you on your rights under the relevant state legislation, assess whether your actions fall within the self-defence provisions, and help you navigate any investigation.
Australia's legal framework does allow for civilian heroism. But it requires proportionality, restraint, and a clear understanding of where the law draws the line — before, not after, you need it.
