A collection that starts with two rifles rarely stays at two, and the safe you buy today needs to survive category upgrades, extra calibres and a growing ammunition stockpile without forcing a second purchase in 2026 or 2027.
- Secuguard GS3K holds up to 10 long arms across Category A, B, C, D and H compliance classes — Buy for the anchor cabinet.
- Guardall T25 combines handgun and ammunition storage in one 3 gun safe cabinet upgrade — Buy for pistol owners expanding fast.
- Guardall SN25 is a dedicated ammunition safe, not a firearm cabinet — Consider it as a compliance add-on, never a substitute.
- Mixing rifles, handguns and ammunition in one non-compliant cabinet is the most common reason storage checks stall in 2026.
Why this matters
Most first-time buyers pick a 3 gun safe cabinet sized for the collection they own on day one, not the one they'll own in 2027. That works fine until a second calibre, a handgun licence variation, or a bulk ammunition purchase turns a compliant cabinet into a non-compliant one overnight.
Australian firearm storage law separates rifles, handguns and ammunition into distinct obligations depending on the state and licence category. A cabinet rated for Category A-D long arms does not automatically satisfy Category H handgun storage, and ammunition frequently needs its own locked compartment regardless of what's printed on the gun cabinet's compliance plate. The gear that suits a growing sporting shooter's setup in year one rarely covers the same collector two years later without an add-on purchase.
This guide ranks three cabinets that cover the three separate obligations a growing collection eventually runs into: rifle capacity, handgun storage, and ammunition separation.
How this list was ranked
Each cabinet was assessed against three questions a collector actually asks: does it cover the compliance category it claims, does it leave headroom for growth, and does it solve one storage problem cleanly rather than half-solving three. Cabinets that try to do everything at a bargain price tend to fail one of those three tests, usually ammunition separation.
The three picks below aren't interchangeable. They cover different parts of a compliant setup, and a serious collection in 2026 will likely end up owning more than one of them rather than choosing between them.
The ranked list
1. Secuguard GS3K — the anchor cabinet
The Secuguard GS3K is built to hold up to 10 long arms and is rated across Category A, B, C, D and H, which covers the bulk of rifle and shotgun licensing most collectors start with. That capacity number matters because it's the difference between buying once and buying twice — a cabinet sized for four rifles gets replaced the moment a fifth arrives.
For a collection still in its early stages, this is the cabinet to buy first. It absorbs growth for years rather than months, and the multi-category rating means a licence variation doesn't force a storage upgrade alongside it. Verdict: Buy as the primary cabinet in any 3 gun safe cabinet setup built for expansion.
2. Guardall T25 — the pistol add-on
The Guardall T25 is built specifically around handguns and ammunition, pairing the two in one unit rather than treating pistols as an afterthought bolted onto a rifle cabinet. That distinction matters because a handgun licence variation is one of the fastest ways a growing collection outpaces its original storage plan.
Buyers who start with rifles and add a pistol licence in year two usually discover their existing cabinet wasn't built for it. The Guardall T25 closes that gap without requiring a full cabinet swap. Verdict: Buy for anyone whose collection is expanding into handguns.
3. Guardall SN25 — the compliance backstop
The Guardall SN25 is an ammunition-only safe, and it's ranked third deliberately — it's not a firearm cabinet and shouldn't be marketed or bought as one. What it does well is solve the ammunition separation requirement that trips up collectors who assume their rifle cabinet already covers it.
This is the cabinet that gets skipped most often, usually because buyers assume ammunition storage is covered by the firearm safe next to it. It frequently isn't. Verdict: Consider the Guardall SN25 as a companion purchase once the rifle and handgun cabinets are sorted, not as a first buy.
“If the cabinet doesn't separate ammunition from firearms, it isn't compliant storage — it's a liability with a lock on it.”
Comparison table
| Cabinet | Best For | Key Detail | Verdict |
|---|---|---|---|
| Secuguard GS3K | Rifle collectors needing headroom | Up to 10 long arms, Category A-D and H | Buy |
| Guardall T25 | Handgun owners adding pistols | Combined handgun and ammunition compartments | Buy |
| Guardall SN25 | Ammunition separation compliance | Dedicated ammunition-only storage | Consider |
Where to buy
- Match the compliance plate category (A, B, C, D or H) against your actual licence categories before paying — a cabinet rated for the wrong category doesn't pass an inspection just because it locks.
- Treat the ammunition safe as a companion purchase, not a substitute for firearm storage. Most state legislation treats the two as separate obligations even when a single cabinet claims to cover both.
- Confirm bolt-down requirements and delivery access before ordering, especially for garage or shed installs where a heavy cabinet can't be repositioned easily after arrival.
FAQ
What is a 3 gun safe cabinet?
A 3 gun safe cabinet refers to a small set of purpose-built safes — typically one for rifles, one for handguns, and one for ammunition — that together cover a growing firearm collection's full storage obligations. A single cabinet rarely satisfies all three categories at once.
Do I need a separate ammunition safe from my gun cabinet?
In most Australian states, yes — ammunition storage is treated as a separate obligation from firearm storage even when both are kept in the same room. A dedicated ammunition safe like the Guardall SN25 solves this cleanly rather than relying on a rifle cabinet's built-in compartment.
How many rifles fit in a Category A-H gun safe?
The Secuguard GS3K holds up to 10 long arms across Category A, B, C, D and H, which covers most growing rifle and shotgun collections without an upgrade. Capacity varies by model, so check the rating on any cabinet before buying.
What's the difference between a handgun safe and a rifle cabinet?
A handgun safe like the Guardall T25 is built around Category H compliance and pistol dimensions, while a rifle cabinet is sized and rated for long arms under Category A-D. The two aren't interchangeable, and a licence covering both categories usually needs both types of storage.
Can one cabinet store rifles and handguns together?
Some multi-category cabinets are rated for both, but many collectors end up needing separate storage as their licence categories expand. Checking the compliance plate against your specific licence categories is the only reliable way to confirm coverage.
How much does a compliant gun safe cost in Australia in 2026?
Pricing varies by capacity, lock type and compliance category, so check current pricing directly rather than relying on a single figure. A three-piece setup covering rifles, handguns and ammunition typically costs more than a single all-in-one cabinet but avoids the compliance gaps that come with combined units.
Is a Guardall gun safe cabinet good for a growing collection?
Guardall's T25 and SN25 are built to handle handgun and ammunition storage specifically, making them a strong companion purchase alongside a larger rifle cabinet like the Secuguard GS3K. Neither is designed to be a standalone solution for a full, growing collection.
What happens if my gun safe cabinet doesn't match my licence category?
A mismatched compliance category is one of the most common reasons a firearms storage check fails, regardless of how secure the cabinet actually is. Matching the plate rating to your licence categories before purchase avoids the problem entirely.
One last thing
Most collectors buy the second rifle cabinet before they buy the ammunition safe — backwards, given that ammunition separation is the compliance detail that trips up storage checks more often than capacity ever does. If budget forces a choice in 2026, the Guardall SN25 solves a more common problem than a bigger rifle cabinet does.
