Understand knife laws across every Australian state and territory. A practical guide to buying, carrying, and importing knives legally in Australia.
Are Knives Legal in Australia?
Yes — most knives are legal to own in Australia. Ownership is not generally restricted. The rules become more specific when it comes to importing certain knife types and carrying knives in public, where state and territory laws apply.
This guide covers:
- Federal knife import laws (what you can and cannot bring into Australia)
- Carry rules for every state and territory
- What counts as a "reasonable excuse"
- Which knife types are banned or restricted

This article is provided for general information purposes only. It does not constitute legal advice and should not be relied upon as such. Knife laws in Australia are complex, vary between states and territories, and are subject to change. The information below reflects our understanding at the time of writing but may not reflect the most current legislation in your jurisdiction.
If you are unsure whether a knife is legal to own, carry or import in your situation, you must seek independent legal advice from a qualified solicitor in your state or territory. Penalties for carrying or importing prohibited knives can be severe, including fines and imprisonment.
Federal Knife Import Laws
Before state laws apply, federal importation rules set the baseline. Knife importation into Australia is regulated under the Customs Act 1901 (Cth) and the Customs (Prohibited Imports) Regulations 1956 (Cth), Schedule 13.
Knives Prohibited from Import (without a permit)
- Flick knives / switchblades — any knife that opens automatically by pressing a button, spring or gravity mechanism
- Butterfly knives (balisongs) — knives with a split handle that rotates around the blade tang
- Gravity knives — knives that open by the force of gravity or centrifugal force
- Automatic knives — knives that open automatically by mechanical means
- Disguised knives — knives concealed within everyday objects (pens, combs, belt buckles)
- Ballistic knives — knives capable of projecting the blade
- Knuckle knives / push daggers — knives with a crosswise handle designed to be gripped in the fist
Knives That Are Generally Legal to Import
Most standard knives used for outdoor, trade, kitchen, and sporting purposes are not prohibited imports. This includes:
- Fixed blade hunting, bushcraft and outdoor knives
- Standard folding knives (manual open, no automatic mechanism)
- Kitchen and chef's knives
- Multi-tools
- Swiss Army knives
All knives sold through Outback Edge Imports are stocked within Australia and comply with federal import regulations. Browse our Hunting Knives, EDC Knives, and Folding Knives.
State-by-State Knife Carry Laws — Quick Reference
There is no national blade length law in Australia. Knife carry laws are set by each state and territory. The common thread across all jurisdictions is that carrying a knife in public without a reasonable excuse or lawful purpose is an offence.
| State / Territory | Carry in public | Blade length limit | Key legislation |
|---|---|---|---|
| Queensland | Reasonable excuse required | None specified in law | Weapons Act 1990 (Qld) |
| New South Wales | Reasonable excuse required | None specified in law | Summary Offences Act 1988 (NSW) |
| Victoria | Lawful excuse required | None specified in law | Control of Weapons Act 1990 (Vic) |
| Western Australia | Reasonable excuse required; stricter categories apply | None specified in law | Weapons Act 1999 (WA) |
| South Australia | Reasonable excuse required | None specified in law | Summary Offences Act 1953 (SA) |
| Northern Territory | Lawful excuse required | None specified in law | Weapons Act (NT) |
| ACT | Reasonable excuse required | None specified in law | Prohibited Weapons Act 1996 (ACT) |
| Tasmania | Reasonable excuse required | None specified in law | Police Offences Act 1935 (Tas) |
Note: This table is a general summary only. Legislation changes, enforcement varies, and definitions of "reasonable excuse" are applied case by case. This is not legal advice — verify current laws in your jurisdiction before carrying any knife in public.
Queensland Knife Laws
In Queensland, knife possession in public is governed by the Weapons Act 1990 (Qld). It is an offence to carry a knife in a public place without a reasonable excuse.
What counts as a reasonable excuse in QLD?
- Work use — a chef carrying a knife to or from work, a tradesperson carrying a utility knife on the job
- Lawful outdoor activity — hunting, fishing, camping where the knife is appropriate to the activity
- Food preparation
- Sports or recreational activity
- Lawful knife collecting
What is NOT a reasonable excuse in QLD?
- Self-defence — this is explicitly not a lawful excuse under QLD law
- Carrying "just in case"
- General EDC without a specific lawful purpose
Queensland also prohibits certain knife types from being possessed at all, including flick knives, gravity knives and butterfly knives.
New South Wales Knife Laws
NSW knife carry in public is primarily governed by section 11C of the Summary Offences Act 1988 (NSW), which makes it an offence to carry a knife in a public place or school without a reasonable excuse.
What counts as a reasonable excuse in NSW?
- Use at work — a butcher, chef or tradesperson carrying a knife appropriate to their trade
- Lawful recreational activity — fishing, camping, hunting
- A cultural or religious practice
- Exhibiting the knife as part of a collection
The Weapons Prohibition Act 1998 (NSW) covers prohibited weapons, which include switchblades, butterfly knives, push daggers, and similar items — these are prohibited to possess in NSW regardless of excuse.
Victoria Knife Laws
Victoria's knife laws sit under the Control of Weapons Act 1990 (Vic). Carrying a controlled weapon (which includes most knives) in a public place is an offence without a lawful excuse.
What counts as a lawful excuse in VIC?
- Carrying the knife for use in your occupation (chef, butcher, tradesperson)
- Carrying for a lawful sport, recreational activity, or entertainment
- Carrying for genuine collection purposes
- Carrying for use in a place of worship or for a cultural purpose
Victoria has additional school zone provisions — carrying any knife on or near school grounds is treated very seriously regardless of excuse. Victoria also has specific prohibited weapon categories that cannot be possessed at all.
Western Australia Knife Laws
WA's knife carry laws are governed by the Weapons Act 1999 (WA). WA is generally considered to have stricter knife regulations than eastern states, and its list of prohibited weapons is broader.
Carrying a knife in a public place in WA requires a reasonable excuse. WA law distinguishes between prohibited weapons (cannot be possessed without a licence or permit) and offensive weapons (possession in public requires a reasonable excuse).
What counts as a reasonable excuse in WA?
- Carrying for work purposes (trades, food preparation, professional use)
- Carrying for outdoor recreation (fishing, hunting, camping) where the knife is reasonably appropriate to the activity
- A religious, cultural or educational purpose
WA residents should exercise particular caution — penalties for weapons offences in WA are significant, and the definition of "reasonable excuse" is interpreted strictly. If in doubt, seek legal advice before carrying.
South Australia Knife Laws
In South Australia, public carry of a knife without a lawful excuse is an offence under the Summary Offences Act 1953 (SA). SA also has provisions under the Serious and Organised Crime (Control) Act 2008 (SA) relevant to prohibited weapons.
What counts as a reasonable excuse in SA?
- Carrying for work — tradespeople, chefs, food industry workers
- Carrying for lawful outdoor activities — fishing, camping, hunting
- Sport or recreation where the knife is appropriate
Prohibited weapons in SA include switchblades, gravity knives and butterfly knives — possession of these is an offence regardless of excuse.
Northern Territory Knife Laws
The Northern Territory has knife carry provisions under its Weapons Act (NT). As with other jurisdictions, carrying a knife in public without a lawful excuse is an offence. The NT's Weapons Act lists prohibited weapons that cannot be possessed.
Reasonable excuses follow broadly similar categories to other states — work use, outdoor recreation, sport — but enforcement context in the NT can differ significantly from major cities in other states.
Note: NT legislation has been subject to updates in recent years. Always verify current laws at the NT Government's website or consult a local solicitor.
ACT Knife Laws
In the Australian Capital Territory, knife possession and carry is regulated under the Prohibited Weapons Act 1996 (ACT). The ACT prohibits possession of certain knife types outright and requires a lawful excuse to carry other knives in public.
The ACT's reasonable excuse provisions follow the national pattern: occupational use, lawful recreation, sport and collection are recognised. Self-defence is not a lawful excuse in the ACT.
Tasmania Knife Laws
Tasmania's knife carry laws operate under the Police Offences Act 1935 (Tas) and, for prohibited weapons, the Firearms Act 1996 (Tas) and related regulations. Carrying a knife in a public place without a lawful excuse is an offence.
Reasonable excuse principles follow the national pattern — occupational use, lawful outdoor recreation and sport are recognised. Carrying a hunting or fishing knife while engaged in those activities is generally lawful; carrying the same knife in a public space without that context is not.
What Counts as a "Reasonable Excuse"?
Every Australian state and territory uses the "reasonable excuse" or "lawful excuse" standard for public carry. While the specific wording varies by jurisdiction, the underlying principles are consistent.
Generally accepted as a reasonable excuse (across all states)
- Occupational use — chef, butcher, tradesperson, farmer, fisherman, hunting guide carrying a knife appropriate to their work
- Outdoor recreation — fishing, camping, hunting, bushwalking where the knife is appropriate to the activity and you are travelling to or from that activity
- Sport — certain knife-related sports and activities
- Collecting — carrying a knife to or from a collector's event, show or appraisal
- Cultural or religious purpose — recognised in most jurisdictions (e.g. Sikh kirpan)
Not a reasonable excuse (in any Australian jurisdiction)
- Self-defence — not a lawful excuse in any Australian state or territory
- Carrying "just in case" — no specific purpose defeats the reasonable excuse requirement
- Habit or routine — carrying out of habit, without a specific lawful reason, is not sufficient
The test is applied contextually. A chef walking to work with a knife roll is clearly lawful. The same person carrying a fixed blade on a Saturday night in the CBD without a reason is not. Intent, context and the nature of the knife all matter.
Which Knives Are Legal to Own at Home?
Ownership at home (as opposed to carry in public) is far less restricted. Most standard knives — including fixed blade hunting knives, folding knives, kitchen knives, and multi-tools — are legal to own in all Australian states and territories, provided they are not on the prohibited import list.
Prohibited weapon types (switchblades, butterfly knives, gravity knives etc.) are banned from possession in most states regardless of location. Owning one at home does not make it lawful.
