A standard 5 gun safe tops out fast once a collection grows past the first few rifles — this guide ranks the storage that actually holds a larger collection under Australian firearm laws in 2026.
- Secuguard GS3K holds 10 long arms across five firearm categories (A, B, C, D, H) — Buy for larger collections.
- A basic 5 gun safe undersizes fast; Guardall SN25 keeps ammunition compliant and separate — Buy.
- Guardall T25 covers handguns and ammunition together for mixed Category H collections — Buy.
- CMI CR5 Commander adds time-delay relock for high-value collections — Consider, not essential.
- A hardware-store gun cabinet rarely meets category compliance once a collection passes five firearms — Skip.
Why this matters
Most gun safes sold in Australia are built around a five-firearm capacity because that covers the average shooter. That capacity stops working the moment a collection grows into double digits, or the moment rifles under Category A, B, C or D sit alongside a handgun under Category H.
State police departments inspect for compliance, not intent — a rack of rifles crammed into a five-gun cabinet fails an audit even if the door locks fine. Requirements differ by state, so check how the gun safe rules stack up state by state before buying anything in 2026.
For collectors past the five-gun mark, the right safe does two things a basic model doesn't: it holds more long arms without stacking them on top of each other, and it separates ammunition storage the way most state legislation requires. Every gun safe carried by Buy A Safe in 2026 gets judged against exactly those two points before capacity or price even comes into it.
How we ranked
Every safe on this list is judged against three things that matter for larger collections: rated capacity for long arms, compliance with Australian firearm storage categories (A, B, C, D, H), and whether ammunition can be locked away separately from the firearms themselves.
Basic domestic safes and hardware-store gun cabinets are left off this list — they're built for a five-gun household, not a collection that's outgrown one. Pricing, lock type and fire rating get weighed too, but capacity and compliance decide the ranking first. Every product below ships and installs in Australia in 2026, and every verdict assumes the reader is storing more firearms than a starter safe was designed for.
The ranked list
1. Secuguard GS3K Cat A/B/C/D/H – 10 Rifle Gun Safe
The flagship pick. The Secuguard GS3K Cat A/B/C/D/H 10 Rifle Gun Safe is built for exactly the problem this guide addresses — it's rated to hold 10 long arms across five compliance categories, so a mixed collection of bolt-actions, semi-autos and a registered handgun can sit in one cabinet instead of two.
That's double the standard five-gun capacity most shooters start with. If a collection has already outgrown a basic cabinet, this is the safe that stops a second purchase being necessary in 2026. Verdict: Buy — it's the clearest fit for a larger collection on this list.
2. Guardall T25 Hand Guns & Ammo Safe
The mixed-collection pick. The Guardall T25 Hand Guns & Ammo Safe is built to hold handguns and ammunition in one unit, which matters when a collection spans Category H alongside long arms stored elsewhere.
Running a rifle safe and a separate handgun-and-ammo safe side by side is standard practice for anyone holding more than one firearm category — it's also what most state compliance checks expect to see. Verdict: Buy — pair it with a long-arm safe rather than trying to fit everything into one cabinet.
3. Guardall SN25 Ammunition Safe
The compliance non-negotiable. The Guardall SN25 Ammunition Safe exists for one job: keeping ammunition locked away from the firearms themselves, which several Australian states require once storage moves past a token amount.
Skip this and the best rifle safe on the market still fails an inspection. Verdict: Buy — treat it as mandatory, not optional, once a collection grows past a handful of firearms.
4. CMI CR5 Commander Safe TDR
The security upgrade. The CMI CR5 Commander Safe isn't marketed as a gun safe, but its time-delay relock function is worth a look when a collection includes high-value optics or documents that need a second layer of protection alongside the firearms.
It's not a substitute for a compliant rifle or handgun safe. Verdict: Consider — an add-on for high-value collections, not a first purchase.
5. Guardall HV3 Home Safe
The overflow option. The Guardall HV3 Home Safe handles the paperwork that piles up around a growing firearm collection — licences, permits, spare optics — without eating into the capacity of a dedicated gun safe.
It won't hold a single firearm under most state rules. Verdict: Consider — useful alongside a compliant gun safe, never instead of one.
Comparison table
| Safe | Built for | Key detail | Verdict |
|---|---|---|---|
| Secuguard GS3K Cat A/B/C/D/H | Long arms, mixed categories | 10 long arms across five compliance categories | Buy |
| Guardall T25 Hand Guns & Ammo Safe | Handguns plus ammunition | Combined storage for Category H plus ammo | Buy |
| Guardall SN25 Ammunition Safe | Ammunition only | Separates ammo from firearms per state rules | Buy |
Where to buy
- Buy from a dealer who can confirm the safe's rated firearm category in writing, including Buy A Safe — a generic "gun safe" listing on a marketplace often isn't rated for anything.
- Check the ammunition storage requirement for your own state before buying just one unit — a rifle safe alone doesn't satisfy every state's rules in 2026.
- Get delivery and anchoring arranged at the time of purchase. A 10-gun-capacity safe is too heavy to move twice, and an unbolted safe fails most compliance checks regardless of what's locked inside it.
FAQ
What's the best gun safe for a collection bigger than five firearms?
The Secuguard GS3K Cat A/B/C/D/H holds 10 long arms across five firearm categories, which covers most collectors who've outgrown a standard 5 gun safe. Pair it with a dedicated ammunition safe to meet most state storage rules in 2026.
Is a 5 gun safe big enough for a growing collection?
A 5 gun safe covers a starter collection but runs out of room fast once a second rifle style or a registered handgun gets added. Most collectors upgrade to a 10-gun-rated safe like the Secuguard GS3K within a few years.
Do I need to store ammunition separately from firearms in Australia?
Several Australian states require ammunition to be stored separately from firearms once holdings pass a small amount. The Guardall SN25 Ammunition Safe is built specifically for that separation requirement.
Can one safe hold both handguns and rifles legally?
It depends on the safe's rated category and the relevant state's rules — safes like the Guardall T25 are rated for handguns and ammunition together, but long arms generally need their own compliant storage.
How much does a large-capacity gun safe cost in Australia in 2026?
Pricing varies by capacity, steel thickness and lock type, so check current listings directly rather than relying on a fixed figure. Larger, higher-category safes generally cost more than a basic 5 gun safe.
What happens if a gun safe fails a police compliance check?
A safe that doesn't match the registered firearm categories, or that stores ammunition alongside firearms where that's not permitted, can fail an inspection even when it's locked and bolted down. Confirming category ratings before buying avoids this.
Is a hardware-store gun cabinet enough for a larger collection?
Basic hardware-store cabinets are usually built for entry-level five-gun households and often lack the rated capacity or category compliance a larger collection needs. A purpose-built safe like the Secuguard GS3K is the safer long-term buy.
Should a collector buy one big safe or two smaller ones for a mixed collection?
Most collectors with mixed categories run a long-arm safe alongside a separate handgun-and-ammo unit like the Guardall T25, rather than one safe for everything. It's also what most state compliance checks expect to see.
One last thing
The detail most first-time buyers miss isn't capacity — it's compliance category. A safe rated for Category A and B doesn't automatically cover a Category H handgun or a Category D restricted firearm, and that fine print matters more than how many guns physically fit inside. Check the category rating before checking the gun count, and browse the full gun safe range on Buy A Safe before making the call in 2026.
