Installing a home safe in Australia costs more than the sticker price of the safe itself once you factor in delivery, anchor bolts, floor prep and whether you hire a locksmith or bolt it down yourself.
- Home safe installation cost in Australia hinges on floor type and safe weight, not just the safe's price tag.
- Safes under roughly 150kg need bolting to stop walk-out theft — this is the main DIY-vs-locksmith decision point.
- A Chubb Mini Banker MkII Size 1 (M-15) starts at $1,795 before any installation cost is added.
- Timber suspended floors often need extra bracing before anchor bolts will hold — check this before delivery day.
Why this matters
Most buyers price a home safe by the retail tag and stop there. That's the wrong number to budget against.
The real home safe installation cost in Australia is a stack: the safe, delivery to the exact room, the correct anchor bolts for a safe installation, and either your own labour or a locksmith's callout. Skip any one of those steps and the safe sits in a hallway unbolted, which defeats the point of buying one. Picking the right size safe for your home before you buy avoids half the installation headaches described below.
What you'll need
- A tape measure — check doorways, hallway turns and stairwells before the safe arrives, not after
- Confirmation of your floor type: concrete slab versus timber suspended floor
- Rated masonry anchor bolts matched to the safe's fixing holes
- A masonry-rated power drill if you're bolting the safe yourself
- A furniture dolly and a second person for anything over 100kg
- A booked locksmith or safe technician if you're going professional
- The safe itself, sized and weighted for the room it's going into
The steps
1. Measure access before you buy, not after delivery
This step accomplishes exactly one thing: it stops a $2,000-plus safe getting stuck in your hallway. Measure the narrowest doorway, any stairwell turn, and the final resting spot with a few centimetres of clearance on each side. Buyasafe home safes range from compact desk units to freestanding models over 100kg, and access width is the single biggest cause of failed deliveries. Common mistake: measuring the front door but forgetting the internal hallway turn into the study or bedroom.
2. Confirm the floor type
Anchor bolts only work if there's something solid to bite into. A concrete slab takes a masonry anchor bolt reliably; a timber suspended floor usually needs the bolt driven into a joist, which may mean lifting a floorboard or adding a plywood backing plate. Ground-floor homes on a slab are the easiest and cheapest install; elevated timber floors in older Queenslanders or beach houses add a step. Common mistake: assuming carpet means concrete underneath — plenty of older homes have carpet over particleboard.
3. Decide DIY vs professional installation
Bolting a safe yourself is realistic if the floor is concrete, the safe is under roughly 150kg, and you own a masonry drill. Above that weight, or on a timber floor, a locksmith or safe technician earns their fee — wrong-size anchor bolts or a badly drilled hole in a slab can crack tile and won't hold under a determined pry attempt anyway. Common mistake: using standard wall plugs instead of concrete-rated anchor bolts because they were already in the shed.
4. Select the correct anchor bolts
The safe's fixing holes dictate bolt diameter — most home safes use M8 to M12 masonry anchors. Undersized bolts are the single most common reason a bolted safe still gets ripped out during a break-in. The anchor bolt selection guide covers which bolt size matches which safe class. Common mistake: buying bolts by length alone and ignoring the shear rating.
5. Book delivery to the exact room
General courier delivery to the kerb is not the same as delivery to the room. Heavier safes need a two-person carry or a stair-climbing trolley, and that's a separate booking line, not an assumption. Confirm this before delivery day, because a driver who can't get a 90kg safe past the front step will leave it on the porch. Common mistake: ordering standard freight for a safe over 80kg and expecting room delivery anyway.
6. Bolt the safe down
This is the step that actually stops theft. Position the safe, mark the fixing holes, drill to the anchor manufacturer's depth (usually 60-80mm into concrete), insert the anchors, and torque the bolts to snug — not over-tight, which can crack the drilled hole in tile or thin slab. The full walkthrough is in how to bolt down a safe correctly. Expected outcome: the safe doesn't shift when you push it with full body weight. Common mistake: drilling the pilot hole undersized, which makes the anchor spin instead of expanding.
7. Test the lock and record the code
Before you load anything valuable in, open and close the safe five to ten times, including a full power-off test if it's electronic. Write the combination or code down and store it somewhere that isn't inside the safe. Common mistake: setting a factory default code and never changing it — a habit that shows up constantly in insurance claim reviews.
8. Add up the real total
Once delivery, bolts, and labour (DIY time or locksmith fee) are on top of the safe price, the total budget looks different from the sticker price alone. A Chubb Mini Banker MkII Size 4 (M-75) lists at $2,295 and a Size 6 (M-125) at $2,995 — either is a reasonable base before install costs land on top. Common mistake: budgeting only for the safe and getting surprised by the anchor bolts and drilling consumables.
Troubleshooting
- Doorway too narrow for the safe — measure the tightest turn before ordering, not the front door. Some safes ship on their side or with removable feet to shave centimetres.
- No concrete slab under the carpet — pull back a corner and check, or ask your builder. Timber floors need a joist-mounted backing plate before bolting.
- Anchor bolts spin without biting — the pilot hole is undersized or too shallow. Redrill to the manufacturer's exact depth and diameter, don't force a bigger bolt into a small hole.
- Safe isn't level after bolting — use packing shims under the base before final torque, then re-check with a spirit level.
- Delivery driver won't carry the safe past the ground floor — confirm room delivery and stair access at time of booking, in writing, not verbally on the day.
- Electronic lock won't complete setup after installation — most failures are a battery seated wrong or a factory code entered incorrectly on the first try; reset per the manual before assuming a fault.

What to do next
If the whole point of reading this is to avoid doing the bolting yourself, some suppliers bundle delivery and fitting together. The guide on choosing a safe with delivery and installation included covers what to check before you assume that's the case.
FAQ
How much does it cost to install a home safe in Australia?
Home safe installation cost in Australia depends on the safe's price, delivery to the room, anchor bolts, and labour — a $1,795 to $3,000 safe still needs bolts and either DIY time or a locksmith callout added on top in 2026.
Do I need a professional to install a home safe?
Not always — a concrete floor and a safe under roughly 150kg is a realistic DIY bolt-down job. Timber suspended floors or heavier safes are where a locksmith earns the fee.
What size anchor bolts does a home safe need?
Most home safes use M8 to M12 masonry anchor bolts depending on the fixing holes and the safe's weight class. Undersized bolts are the most common reason a bolted safe still fails during a break-in attempt.
Can a home safe sit on a timber floor?
Yes, but the anchor bolts need to reach a joist or a plywood backing plate rather than just the floorboard, which usually means lifting a board before installation.
Is it cheaper to bolt a safe down myself?
Yes, DIY bolting on a concrete floor avoids a locksmith callout fee, but it requires the correct masonry-rated anchor bolts and a drill capable of the required hole depth.
Does a heavier safe cost more to install?
Yes — safes over 100kg typically need two-person delivery or a stair-climbing trolley, and that's usually a separate line item from standard kerb delivery in 2026.
What happens if a safe isn't bolted down?
An unbolted safe under roughly 150kg can be carried out of a house whole during a break-in, which defeats the security purpose of buying one in the first place.
One last thing
The cheapest part of this whole process is the anchor bolts — a few dollars each — and it's the part homeowners skip most often after spending $2,000-plus on the safe itself. Buyasafe's home safe range covers the size and weight brackets discussed above, but the safe only does its job once it's actually fixed to the floor it sits on.
