Every December the crew downs tools, the gate gets chained, and a site full of plant and materials sits empty for weeks. The construction site theft Christmas problem isn't new, but the figures rarely sit in one place.
Here they are: what's published on holiday-period theft, what walks off site, what a break-in costs, and the delay that follows when the crew comes back.
No Australian police force publishes a construction site theft Christmas figure, but the surrounding numbers are clear. Victorian tradies lost more than $33 million in tools in 2023, and insurer NTI saw a 35 per cent rise in claims over the summer of 2024 to 2025. Tools, copper, appliances, fuel and plant are the usual losses, and the bigger cost is the time lost replacing them in January.
SafeWork NSW calls the Christmas and New Year break the longest shut down in the construction industry. Finish on Friday 18 December and come back on Monday 4 January, and your site sits empty for 17 nights in a row. A weekend gives a thief two nights. The shutdown gives them weeks, with most sites on the street empty too.
Insurers see it. NTI's head of claims said in December 2025 that over the festive shutdown it's "not uncommon for worksites to operate with little to no security". Truck Assist recorded a 35 per cent increase in claims from November 2024 to January 2025, including stolen tools, depot vandalism and fuel theft.
Police record building site theft inside broader categories, so there's no holiday-period line to quote. Our construction site theft statistics post has the year-round numbers. These matter for the break.
| Figure | Where and when | Source |
|---|---|---|
| More than $33 million in hand and power tools stolen from tradies, up 37% in value on the year before | Victoria, 2023 | RACV, citing the Crime Statistics Agency |
| 18,626 power tools and 14,911 hand tools stolen, 12% more items than the year before | Victoria, 2023 | RACV, citing the Crime Statistics Agency |
| 35% increase in overall claims over the summer period | Truck Assist customers, Nov 2024 to Jan 2025 | NTI / Truck Assist |
| On-the-spot fines of $2,700 for a business and $500 for an individual with an unsecured site | NSW, December 2025 | SafeWork NSW |
Distrust any national total without a named source. The Victorian figure only covers tools. Add materials, fuel, copper and plant and the real shutdown number is larger.
Shutting down a build this December?
Our Christmas guide sets out the four layers, fence, lock, light and watch, and the dates to work back from.
Read the shutdown guidePolice and industry bodies agree on the targets. South Australia Police lists building materials, copper, appliances, doors, windows, fittings, electrical cable and tools, and warns against leaving raw materials on site over holiday periods. The Housing Industry Association names hot water units, copper wiring and major appliances as high-risk.
The stage you shut down at decides the loss. Lock-up and fit-out sites lose appliances and copper. Civil jobs lose diesel, plant and cable. Three weeks gives a thief time to come back with a bigger vehicle.
| Target | Why it goes over the break | Sites most exposed |
|---|---|---|
| Power and hand tools | Portable, high value, easy to sell on | Any site with tools left in sheds or containers |
| Copper cable and pipe | Scrap value, stripped in the open with no one around | Fit-out stage builds, new estates, infrastructure |
| Appliances and hot water units | Delivered before the break, installed after it | Residential lock-up and fit-out |
| Fuel | Drained from plant and site tanks at leisure | Civil, roadworks, remote compounds |
| Plant and machinery | Weeks of cover to load and move it | Civil, earthworks, early-stage builds |
The stolen goods are only the first line on the bill. A cut fence, a jemmied container and a machine with its fuel lines cut all need fixing before work restarts. HIA notes that under most of its contracts the builder carries the risk for unaffixed materials, tools and equipment, so the excess and claim admin land on you.
Premiums follow claims. In February 2026 HIA said site theft "increases claims and risk, and insurers price in that risk", with 72 per cent of small builders naming insurance a top pain point. A bad shutdown shows up at renewal.
In NSW, SafeWork inspectors visit sites during the shutdown and can issue notices or on-the-spot fines. Rules differ between states, so check with your regulator. See what WHS inspectors check before the shutdown.
Who's watching your site at 2am on Boxing Day?
Siteguard's Australian-based control room verifies every alarm and responds in real time, nights, weekends and public holidays.
How monitoring worksA theft on 20 December is usually found on the first day back. By then the gear is long gone and the first morning of the year goes to walking the site, listing what's missing and getting a police event number.
HIA says theft delays a build when supplies, equipment or materials can't be replaced, and early January is a hard time to replace anything. Suppliers and hire yards are still ramping up, a stolen hot water unit can be weeks away, and a replacement excavator has to be found. The program slips before a trade turns up, and subbies booked for that week move on.
Claims add their own lag. Without footage, an insurer has only your word for what was on site. Event records from Siteguard Foreman give you the time and entry point on the first morning back.
The cheapest fix is to leave less behind: take tools home, hold high-value deliveries until install, and lock cabs and fuel caps. Our post on protecting plant and machinery over the shutdown covers plant, and the Christmas Shutdown Checklist puts every step on one page.
Whatever stays needs a response, not just a record. Siteguard's solar camera towers keep running after site power goes off, and a Shark Cage locks tools inside the tower's steel casing. With control room monitoring, an operator verifies each alarm, issues audio warnings and the siren, and escalates when required, public holidays included. That's the gap between a break-in on the hard drive and one stopped at the fence. The recommended construction setup pairs Twin Cam towers with that monitoring.
"Last Christmas we had 21 break-ins into our construction site. We installed a Siteguard system on site and this Christmas we only had 1 attempted break-in. It has even saved us the cost of paying for security guards." Kevin, Senior PM, Hines Constructions Pty Ltd
No police force publishes a Christmas-specific figure. Victorian tradies lost more than $33 million in tools in 2023, and insurer NTI reported a 35 per cent rise in claims over the 2024 to 2025 summer.
Tools, copper, appliances, hot water units, windows, fittings and building materials. Civil sites also lose fuel, plant and machinery.
It's the longest unattended stretch of the year, often 17 to 24 nights, with most nearby sites empty too. A theft may not be found until the first day back.
There's no standard figure. It depends on what was taken and how fast it can be replaced in early January. A stolen hot water unit or excavator can hold a crew up for days or weeks.
Under most HIA contracts the builder is responsible for unaffixed materials, tools and equipment and must insure against theft. Check your own contract and policy. This is general information, not legal advice.
Yes. A recorded camera tells you in January what happened in December. With control room monitoring, an operator verifies each alarm, issues warnings and a siren, and escalates when required, public holidays included.
