Gun safe storage laws in Australia differ by state and territory, firearm category, firearm numbers and storage location. This 2026 reference compares NSW, Victoria, Queensland, Western Australia, South Australia, Tasmania, the Northern Territory and the ACT; a brand name or category label alone does not establish compliance.
- Gun safe storage laws by state Australia require checking category, quantity, construction, installation and ammunition security together.
- Victoria specifies at least 1.6mm steel; Tasmania specifies 2mm for A/B and 3mm for C/D/H.
- WA Level 1 specifies a 3mm cabinet and 6mm door; Level 2 specifies 6mm and 10mm.
- A 150kg exemption is not universal: some categories require anchoring regardless of weight.
- Buy A Safe gun safes should be matched to official requirements, not treated as automatically approved nationwide.
Sources checked: 7 October 2026. This is general storage guidance, not legal advice or police approval of a particular installation. Official legislation, police directions and individual licence conditions take precedence. For local context, see the NSW gun-storage guide, then use the official sources below to confirm your arrangement.
Why this matters
Steel thickness is only one part of firearm storage. Locks, hinges, mounting points, access to keys, ammunition separation and the building itself also matter. Requirements can change when you add a handgun, share storage, move a safe into a shed or increase the number of firearms at the address.
Buy A Safe's gun-storage reference is for Australian owners comparing state requirements before choosing and installing a safe. It does not replace your firearms registry's assessment. Keep the product specification and installation plan together so you can compare the whole arrangement with the applicable rules.
Gun safe storage laws by state: Australia at a glance
This table summarises ordinary private-owner arrangements, not dealer, security-company, collector or approved alternative storage rules. Weight thresholds refer to the empty receptacle where the source specifies that basis. Read the relevant section before applying a threshold.
| Jurisdiction | Construction reference | Anchoring reference | Ammunition reference |
|---|---|---|---|
| NSW | Level 1 A/B receptacle; Level 2 C/D/H steel safe. Do not substitute an unsourced national thickness rule. | A/B under 150kg: fix securely; C/D/H: attach to premises structure. | Separate locked container or approved integral lockable steel compartment. |
| VIC | Purpose-built steel receptacle, at least 1.6mm under the police guidance. | Below 150kg empty: bolt to premises structure; category and quantity conditions also apply. | Separate locked container or purpose-built separately lockable compartment. |
| QLD | A/B/C: rigid solid steel or solid timber; D/H: rigid solid steel. | A/B/C below 150kg: fix to building; D/H: bolt to building regardless of weight. | Secure separate container or area; an internal secured ammunition area can be suitable. |
| WA | Level 1: 3mm body/6mm door; Level 2: 6mm body/10mm door; rated-safe and room alternatives exist. | Check current repository installation rules and the approved storage statement; do not import another state's exemption. | Confirm ammunition repository requirements with WA Police, separately from the firearm storage matrix. |
| SA | Level one safe: 2mm body and door; level two safe: 3mm body and door. | Below 150kg empty: at least two anchor points into solid structure. | Separate locked storage with an unlocking mechanism different from the firearm safe. |
| TAS | A/B: 2mm metal; C/D/H: 3mm metal; concrete alternative. | Below 150kg empty: four fixings, split wall/floor or all into either. | Separate locked receptacle or compartment, keyed with a different lock. |
| NT | A/B: 3mm recommended; below 2mm not considered. C/D/H: 6mm door, 3mm remainder minimum, subject to inspection. | A/B above 150kg empty: police guidance allows no fixing; C/D/H and combination cabinet: fix to wall or floor. | Confirm the separate ammunition arrangement with the Firearms Policy and Recording Unit. |
| ACT | Up to 10 A/B: approved container arrangements; more than 10 A/B and C/D/H: specified safe construction, including 3mm steel option. | Up to 10 A/B below 150kg: at least two suitable anchors; higher-tier safe fixing specifications apply. | Separate locked container of a type approved by the registrar. |
Licence-category table: A, B, C, D and H
Category letters describe firearms, not a single Australian safe certification. Confirm the category of each registered firearm rather than inferring it from the appearance of the firearm or the safe's name. WA's current framework also includes Category E, so this common-letter table is not its complete classification system.
| Category | Storage decision to make |
|---|---|
| A | Check the local A/B baseline and the number stored at the premises. |
| B | Check A/B rules, including material and empty-weight fixing thresholds. |
| C | Do not assume the same upgrade in every state: Queensland groups C with A/B for the basic container rule. |
| D | Check higher-tier construction, mandatory fixing and any alarm requirements. |
| H | Check handgun storage, internal separation where relevant, and additional electronic security requirements. |
Mixed collections must satisfy every applicable storage condition. Use the stricter applicable construction where appropriate, but do not assume that a heavier safe removes a separate alarm, ammunition or access-control obligation.
New South Wales: Level 1 versus Level 2
The NSW Police Level 1 and Level 2 fact sheets, version 3.2 dated December 2025, distinguish A/B firearms from C/D/H firearms. Level 1 describes a commercially manufactured steel or hardwood firearm receptacle; Level 2 describes a commercially manufactured steel safe designed specifically for firearms.
For A/B, a receptacle below 150kg empty must be fixed. The Level 1 fact sheet specifies at least four appropriately secured anchor points for its listed structural mounting arrangements and addresses internal locking security. C/D/H storage requires solid steel fixtures attaching the safe to the premises structure; the fact sheet does not provide the same weight-based exemption.
Ammunition must be in separate locked storage or an approved integral lockable steel compartment. Storage away from the principal residence or other listed permitted settings can add individual firearm locking and monitored alarm requirements. Do not reduce NSW compliance to an advertised steel gauge.
Official source: NSW Police safe storage, including Level 1, Level 2 and Instruments of Approval.
Victoria: 1.6mm steel and the 150kg threshold
Victoria Police's firearm-storage page specifies a purpose-built steel receptacle at least 1.6mm thick, complying with AS/NZS 1594:2002. Below 150kg empty, the receptacle must be bolted to the premises structure. It must be locked with a sturdy lock when firearms are stored.
A clothing locker is not accepted as a firearm receptacle simply because it has been modified. Cartridge ammunition needs separate locked storage; Victoria Police accepts a purpose-built unit with separate lockable firearm and ammunition compartments. Category, quantity and other licence conditions still require checking against Schedule 4 of the Firearms Act 1996.
For a 2026 installation, check the entire arrangement with your Divisional Firearms Officer if there is doubt. Official source: Victoria Police firearm storage.
Queensland: Category C is not grouped with D and H
Queensland Police distinguishes rigid solid-steel or solid-timber containers for A/B/C from rigid solid-steel containers for D/H. For A/B/C, a container weighing less than 150kg must be securely fixed to the frame or floor of a permanent building. D/H containers must be bolted to the frame or floor regardless of that threshold.
The police guidance uses construction and rigidity requirements rather than one minimum steel thickness for every private-owner safe. Firearms are stored unloaded, with the bolt removed or action broken as applicable. Ammunition requires a secure container or area separate from the firearm container; an internal secured ammunition area can be suitable.
Higher quantities and business or collector licences bring additional requirements. Official source: Queensland Police safe storage of weapons and ammunition. The QPS Form 28 storage guidance and QPS storage brochure support the container distinctions above.
Western Australia: use the current storage matrix
WA Police's current Storage and Security information sheet, version V2-1, uses firearm numbers, category and occupied versus unoccupied location to determine storage and security. Its quantity bands are 1–5, 6–15 and 16 or more firearms.
- Level 1 cabinet option: 3mm steel body and 6mm steel door.
- Level 2 cabinet option: 6mm steel body and 10mm steel door.
- Level 3: Grade V safe or compliant secure room or strongroom, rather than a basic plate-steel cabinet.
Alarm and CCTV obligations depend on the matrix. Existing approved storage can have transitional treatment; the official example of four A/B firearms in an occupied home permits continued existing storage until a firearm is added or replaced. Do not apply that example to every licence or location.
For bolting and ammunition separation, confirm the current repository requirements and storage statement with WA Police before installation. Do not rely on older 2mm/3mm WA summaries or a generic 150kg exemption. Official sources: current WA Police Storage and Security information sheet and Firearms Regulations 2024, current consolidated version.
South Australia: safe level and storage level are different
SAPOL defines a level one safe with structural-grade steel at least 2mm thick in the body and door. A level two safe requires at least 3mm in the body and door. Both include door-fit and locking requirements, and safes below 150kg empty require at least two anchors into solid building structure.
Which safe and security tier applies depends on category, quantity and whether storage is under the main roof or in an outbuilding. The total firearms at the premises counts, including shared storage. A storage level can add CCTV or an alarm to a level two safe; it is not just a thicker cabinet.
Ammunition can be inside the firearm safe only in separately secured storage with an unlocking mechanism that cannot unlock the outer safe. Keep each unlocking mechanism out of the other relevant storage space. Read the South Australian storage guide alongside SAPOL storage, safety and security.
Tasmania: 2mm or 3mm, with four fixings below 150kg
Tasmania Police specifies metal at least 2mm thick for A/B and 3mm for C/D/H, with concrete as an alternative. Below 150kg empty, fix the receptacle at least twice to the wall and twice to the floor, or at least four times to either the wall or floor. Use masonry fixing bolts or coach screws as appropriate.
Internal locking and hinge protection are also specified. Ammunition needs a separate locked receptacle or compartment keyed with a different lock. Any Category H firearm, or 10 or more firearms of any category at the premises, triggers an electronic security requirement: a compliant alarm or visual recording device.
The safe alone does not satisfy that additional requirement. See the Tasmanian gun-storage guide and Tasmania Police storage, safekeeping and transport.
Northern Territory: recommended thickness is not the same as a minimum
NT Police recommends at least 3mm metal for A/B cabinets. Thinner construction can be assessed individually for rigidity and reinforcement, but material below 2mm is not considered. The guidance calls for at least two bolt-down points, with four recommended; an A/B receptacle above 150kg empty need not be bolted under that guidance.
For C/D/H, the door minimum is 6mm and the rest of the cabinet minimum is 3mm, subject to individual inspection and approval; 6mm throughout is recommended. These safes must be fixed to the wall or floor. Combination cabinets for handguns have their own individually locked internal-box requirements.
Confirm the ammunition arrangement and cabinet approval with the Firearms Policy and Recording Unit. The construction page is not a complete ammunition checklist. Read the Northern Territory storage guide and NT Police storage requirements.
ACT: more than 10 A/B firearms changes the safe requirement
ACT Policing distinguishes up to 10 A/B firearms from more than 10 A/B and C/D/H. The first group permits specified lockable container arrangements, with at least two suitable anchors below 150kg empty. Firing mechanisms must, if possible, be removed and separately stored as specified.
The higher group requires a specified safe. The steel option uses at least 3mm structural-grade mild steel, continuous welding and detailed door and lock construction. The 3mm figure is not a blanket rule for every ACT storage arrangement. Higher-tier mounting specifications depend on the substrate, and Category D also requires an intruder alarm.
Ammunition belongs in a separate locked container of a type approved by the registrar. Collector arrangements have additional conditions. Read the ACT storage guide and ACT Policing storage requirements.
What can fail a firearm-storage inspection?
An installation can fail even when its steel exceeds the thickness requirement. These are compliance gaps to check, not a ranked list of inspection statistics:
- A cabinet intended for a lower category or quantity than the firearms actually stored.
- Missing anchors where fixing is mandatory, or anchors gripping a non-structural surface.
- A door, hinge arrangement or lock that does not meet the relevant specification.
- Ammunition sharing an unsecured firearm compartment.
- Keys or codes accessible to someone not authorised to possess the firearms.
- Missing electronic security where category, quantity or location requires it.
- Assuming approval at the old address automatically covers a new building or state.
Before an inspection, compare the product specification, actual installation, firearm count and access arrangements with the official source. Photographing the installation helps document it but is not a substitute for compliance or approval.
Match Buy A Safe models to the applicable category and state
Buy A Safe's product specifications provide a starting shortlist, not nationwide police certification. The two models below both specify a 6mm body and 8mm door. Their stated category suitability does not override local installation, locking, compartment or electronic-security requirements.
| Model | Best for | Documented construction | Important limitation |
|---|---|---|---|
| Secuguard - GS3KL Cat A B C D & H - 10 Rifle Gun Safe | Comparing a 10-rifle model with a separately locked internal compartment | 6mm body, 8mm door; 183kg; listed NSW Level 1/2 and A/B/C/D/H suitability | An 8mm door does not meet WA's 10mm Level 2 cabinet-door specification. |
| CMI Sports Shooter Rifle Safe SS14-D | Comparing a larger 14-rifle model | 6mm body, 8mm door; 274kg; listed Level 1/2 and A/B/C/D/H suitability | Weight does not remove mandatory fixing for categories that require it; the top cupboard specification alone does not establish ammunition separation. |
Shortlist either model only after checking your local category requirements. For WA Level 2, do not buy either as a qualifying plate-steel cabinet solely because its product page says Level 2: WA and NSW use different specifications. Confirm any alternative rated-safe pathway independently.
FAQ
Are gun safe storage laws the same across Australia?
No. Construction, anchoring, ammunition and electronic-security requirements vary by state and territory, category, quantity and location.
Does every gun safe under 150kg need bolting down?
Several jurisdictions use a 150kg empty-weight threshold, but it is not a national rule. Some higher categories require fixing regardless of weight; check your local conditions.
What steel thickness does a gun safe need in 2026?
There is no single Australian minimum. Victoria's police guidance specifies 1.6mm; Tasmania specifies 2mm for A/B and 3mm for C/D/H; WA cabinet levels have separate body and door specifications.
Can ammunition be stored inside the firearm safe?
Some jurisdictions allow a separately locked internal compartment, but the separation and key requirements vary. An open shelf behind the firearm lock is not equivalent to separately secured ammunition storage.
Does an A/B/C/D/H product label prove nationwide compliance?
No. A category label must be checked against the applicable state specifications and actual installation; it does not establish police approval of every arrangement.
Do WA Level 2 and NSW Level 2 mean the same thing?
No. WA's Level 2 plate-steel cabinet option specifies a 6mm body and 10mm door. A product advertised for NSW Level 2 must be assessed separately against WA requirements.
When does Tasmania require an alarm or recording device?
Tasmania requires the specified electronic security device where any Category H firearm or 10 or more firearms of any category are stored at the premises.
What should I check before moving a gun safe interstate?
Check the destination registry's category, quantity, construction, installation, ammunition and address-notification requirements before storing firearms there. Approval of the old arrangement is not transferable evidence of compliance.
One last thing
A label such as Level 2 is meaningful only within the rules it refers to. In 2026, a 6mm-body, 8mm-door safe can carry a NSW Level 2 product description while falling short of WA's 10mm-door cabinet option. Check the jurisdiction before comparing models; that distinction is more useful than choosing by brand alone.
