Holiday security for vacant commercial and construction sites.

Protecting a vacant commercial or construction site over the holidays comes down to three things: a randomised patrol schedule covering the whole shutdown, a monitored alarm with a licensed officer able to attend, and a documented lock-up before the last day. Queensland's building industry treats 22 December to 10 January as non-business days, so most sites sit empty for about three weeks. That is long enough for a break-in to go undiscovered until staff return.

Why a three-week gap changes the risk

Every business closes overnight and most close weekends, and offenders already know that. What makes late December different is the length of the gap and how predictable it is. A weekend gives someone roughly sixty hours. The shutdown gives them three weeks, on a start date published in advance across an entire industry.

Deliveries stop, and there is no one dropping past for a forgotten laptop. The tenants either side of you are closed too, so the informal watching a busy estate provides for free disappears when yours does.

That shifts the risk in two directions. Someone who gets in has time to work, which is why shutdown theft tends to be heavier and better organised than the opportunistic weekend kind. The damage is also found late. By the time anyone walks the site, the evidence is cold and a burst pipe has been running for a fortnight.

The dates that define the 2026/27 window

Under the Building Industry Fairness (Security of Payment) Act 2017, the period from 22 December to 10 January is excluded from the definition of a business day. For the coming break that puts the last business day at Monday 21 December 2026 and the first at Monday 11 January 2027.

The public holidays inside that window:

• Christmas Eve, a part-day public holiday from 6pm on Thursday 24 December 2026
• Christmas Day, Friday 25 December 2026
• Boxing Day, Saturday 26 December 2026, plus an additional public holiday on Monday 28 December because Boxing Day falls on a weekend
• New Year's Day, Friday 1 January 2027

Commercial premises outside construction usually track close to the same window. Even where a business closes only for the public holidays, annual leave keeps most sites thin into late January. Scope cover against the whole quiet period, not the days marked in red.

What actually goes missing

The list is consistent across commercial and construction sites:

• Copper and cable. Light, valuable and quick to strip once someone is inside a switch room or a partly wired build.
• Tools, batteries and small plant. Anything that fits in a ute tray and sells the same week.
• Fuel. From plant, generators and site vehicles left on site over the break.
• Materials and scrap metal. Stacked, uncounted, and rarely alarmed.
• Vandalism and graffiti. Cheap to commit and expensive to remediate. A site left tagged also reads as unwatched, which invites repeat visits.
• Squatting and illegal dumping. The costliest to unwind, because it becomes a legal process rather than a security one. Our guide to trespassers on a commercial property covers where that goes.

Copper is the standout. A Queensland Police copper wire operation centred on Townsville, reported in January 2026, had charged 33 people with 164 offences, with more than 200 thefts reported since January 2025. Detectives said the problem is not confined to Townsville, and new housing estates sat among the targets. That matters across the Ripley Valley and the Springfield growth corridor, where partly completed homes hold cable, hot water systems and appliances behind a temporary fence.

Read your insurance wording before you lock up

Most commercial property policies carry an unoccupancy clause. If premises sit empty beyond a set period, cover can be restricted or fall away. The threshold varies by insurer, commonly between 30 and 90 days, so a three-week shutdown alone usually sits inside it.

The trap is the site already partly empty before December. A tenancy that vacated in early November plus a full shutdown can push you past the threshold without anyone noticing. Two things are worth doing before the last day:

• Read the unoccupancy clause in your own policy rather than assuming the common range applies to you.
• Check what the policy asks of you while the site is empty. Many wordings expect reasonable precautions, and some expect documented inspection. A timestamped patrol report shows that, and an informal recollection will not.

This is general information rather than insurance advice. Your broker can confirm what your specific wording requires.

A patrol plan built for a three-week gap

A shutdown schedule is not an after-hours schedule stretched out:

• Randomise the timing. Fixed pass times are easy to sit and wait out. Randomised arrival carries most of the deterrent value.
• Cover the whole window. The stretch between New Year and the return date is often softer than Christmas week, because the site has been quiet long enough to look abandoned.
• Make each pass a walk. Perimeter, gates, roller doors, site sheds, container locks, and every point where your fence meets a neighbour. A drive-by proves the front gate is shut and nothing else.
• Log it with photographs. Timestamped reports give you an insurance record and a dated picture of the site's condition.
• Pair patrols with response. A sensor tripping at 2am only helps if someone attends. Alarm response puts a licensed officer on site instead of a call to a director three hours up the coast, and our guide on what to do when your alarm goes off covers the decision itself.

Mobile patrols are the backbone of shutdown cover because the cost is shared across sites, which is what makes nightly attendance affordable for three weeks straight. Sites carrying serious value through the break layer a static presence over the highest-risk nights, as our construction site security guide for the Ripley Valley sets out.

The lock-up check before the last day

What happens over the break is largely decided in the week before the site closes.

• Move high-value plant, tools and cable off site or into a locked, anchored container. Anything you shift now cannot be stolen later.
• Photograph the site as you leave it, including serial numbers on plant. It speeds up both the claim and the police report.
• Test the alarm and update the monitoring contact list. A call routed to a number that changed months ago wastes the response.
• Confirm who holds keys, who is authorised to attend, and who we call first.
• Fix lighting now. Replace failed sensors and lamps before you close.
• Remove what helps someone get in: pallets stacked against a fence, a ladder left out, a gate chained but not locked.
• Tell your patrol provider about scheduled visits, so a contractor collecting gear on 3 January is not treated as an intruder.

Book it before the end of November

Licensed officers are scarce in late December, with events, retail and construction all bidding for the same three weeks. Public holidays also carry higher award rates, worth building into the budget rather than meeting on the January invoice.

Booking early also leaves time for a site visit while people are still there. Walking a live site with the people who run it beats assessing an empty lot through a locked gate.

Frequently asked questions

How often should a vacant site be patrolled over the holidays?

There is no fixed rule and no legal minimum. Typical practice for a vacant commercial premises is at least one pass per night through the shutdown, while construction sites and yards holding high-value plant usually get several passes across the overnight window at randomised times. The right number follows what is on site and how exposed the boundary is.

When should I book holiday security cover?

By the end of November for a December shutdown. Licensed officers are in short supply across late December, because events, retail and construction all want cover in the same three weeks. Booking early also lets us walk the site while it is still occupied.
