The 150kg "Magic Number": A Guide to Heavy-Duty Gun Safes in Australia

Date Posted:5 March 2026 

The 150kg Rule: Why a Heavy-Duty Gun Safe is the Ultimate Solution

TL;DR: In states like Victoria, 150kg is the legal weight threshold where bolting a safe down becomes optional for Category A & B firearms. Choosing a heavy-duty safe from XHunter AU simplifies compliance for renters and provides elite-level security through thicker industrial steel.

When it comes to firearm storage in Australia, weight isn't just about bulk—it's about legal freedom. In 2026, as police inspections become more frequent, many shooters are turning to the "Magic Number" that simplifies their life: 150 Kilograms.

What is the 150kg Rule in Victoria?

Under Victorian Law, if an empty gun safe weighs 150kg or more, it is generally not mandatory to bolt it to the floor or wall for Category A & B firearms. This is the ultimate "loophole" for Victorian hunters who are renting. Since the safe is too heavy to be easily removed by thieves, the mass itself satisfies the security requirement, sparing your landlord's floorboards from permanent damage.

"At XHunter AU, our field tests show that the sheer mass of a 150kg+ safe is the best deterrent against 'carry-away' thefts. While a light cabinet can be pried off a wall in minutes, a 150kg beast stays exactly where you put it."

Security Beyond the Weight: Why Heavier Means Stronger

To reach the 150kg mark, manufacturers don't just add lead weights; they use thicker steel. A premium 150kg+ Heavy-Duty Safe typically features 3mm steel bodies and 6mm steel plate doors, making them virtually immune to common pry-bar attacks.

Feature Standard Safe (< 80kg) Heavy-Duty Safe (150kg+)
Legal (VIC A/B) Mandatory Bolt-Down Bolting Optional (Legal Mass)
Steel Body 1.5mm - 2mm 3mm Reinforced
Steel Door 2mm - 3mm 6mm Solid Plate

Expert FAQ: The 150kg Magic Number

1. Is the 150kg rule valid for Category H (Handguns)?
No. In most states, including Victoria, Category H storage requirements are much stricter. Handgun safes almost always require bolting to the floor or wall, regardless of their weight.
2. Is the weight measured with guns inside?
No, the law refers to the weight of the empty safe. Adding ammunition or firearms to a 100kg safe does not make it a 150kg safe in the eyes of the law.
3. Does the 150kg rule apply in NSW or QLD?
While 150kg is the specific threshold in Victoria, other states generally require bolting for all safes. However, a 150kg+ safe is still highly recommended in all states as it makes theft nearly impossible.
4. Why do fire-rated safes weigh so much more?
Fire-rated safes contain thick layers of gypsum or fire-resistant concrete-like material. This insulation adds significant weight, often pushing a mid-sized safe over the 150kg legal limit.
5. What tools are needed to move a 150kg safe?
You will need a heavy-duty appliance trolley (rated for at least 250kg), furniture straps, and ideally 2-3 strong adults. Never attempt to move one alone.
6. Can I bolt down a 150kg safe anyway?
Yes! Even though it's not mandatory in VIC for A/B, we always recommend bolting it down if possible. It provides the highest level of security against professional thieves.
7. What steel thickness should I look for in a heavy-duty safe?
Look for at least 3mm for the body and 6mm for the door. This is the standard for high-security storage at XHunter AU.
8. What is "Swing 'n' Slide" technology?
It's a patented design by Lokaway where the door slides behind the frame before swinging, leaving no gap for a pry bar to enter.
9. Does a 150kg safe protect against fire?
Only if it is specifically "Fire Rated." Not all heavy safes are fireproof. Check the product specs for a fire rating (e.g., 30 or 60 minutes).
10. Does XHunter AU ship 150kg+ safes?
Yes! We use specialized heavy-item carriers to ship our large safes across Australia. Please ensure you have a clear path for delivery at your location.
