Workers’ Compensation for Security Companies

What You Actually Need to Declare

At renewal time, one of the most common surprises for security business owners is a workers’ compensation adjustment notice – a bill for the difference between what was declared at the start of the policy period and what the actual wages turned out to be.

For some businesses, that adjustment is manageable. For others – particularly those that have grown significantly, taken on a large contract, or run a heavy casual workforce through a busy period – the shortfall can be substantial. And it’s entirely avoidable.

Workers’ compensation for security companies is more complex than most industries. Here’s what you need to understand about how it works – and what you need to declare to make sure your cover is genuine.

Why Security Companies Get This Wrong

The complexity in workers’ comp for security businesses comes down to the nature of the workforce. Security operations rarely run on a predictable headcount with stable weekly wages. You have permanent staff, casual guards, part-time employees, and sometimes labour hire arrangements. Shift patterns change. Client contracts start and finish. You take on a major event and your casual wages spike for a month.

Most workers’ compensation policies require you to estimate your total wage bill at the start of the policy year. That estimate becomes the basis for your premium. If your actual wages come in higher – which happens regularly in businesses that take on new contracts or seasonal work – you owe the difference at adjustment.

The problem isn’t the adjustment itself. The problem is when the gap is large enough to create a genuine financial strain, or when the underestimation is significant enough to attract penalties.

In our experience, security businesses most commonly underdeclare in three areas: casual loading on top of base wages, overtime paid during large events or peak periods, and the wages of staff employed by a labour hire company but working under the security business’s direction. Each of these is treated differently depending on the state jurisdiction and the specific circumstances of the arrangement.

What You Must Declare

Every Australian state and territory administers workers’ compensation separately, and the declaration requirements differ in their specifics. But across jurisdictions, the core principle is consistent: you must declare the full cost of wages paid to workers covered by the policy.

Permanent and part-time employees

Base wages, casual loadings, penalty rates, allowances, superannuation (in most states), and leave entitlements all need to be captured. A common mistake is to declare only the base rate for casual guards, excluding the casual loading – which can be 25% or more on top of the hourly rate.

Overtime

If your guards regularly work overtime – which is common in security, particularly in event security and cash-in-transit – that overtime must be included in your wage declaration. Overtime rates significantly increase the average wage per hour, and a policy declared on base rates alone will understate the actual exposure.

Labour hire and contractors

This is where the exposure is often most misunderstood. If you engage workers through a labour hire company, the labour hire company is typically responsible for holding workers’ compensation cover for those workers. However, the practical question – who is directing and controlling the worker – can affect how liability is allocated if a claim arises.

If you use contractors who operate as genuine independent businesses with their own cover, they are generally responsible for their own workers’ compensation. But if a contractor is in substance an employee – working under your direction, using your equipment, at your sites, without genuine independence – the courts and regulators may look through that arrangement. Getting this classification right before a claim arises is considerably simpler than disputing it afterwards.

The Risk of Getting It Wrong

The consequences of underdeclaring wages fall into two categories: financial adjustment at the end of the policy period, and disputed claims.

The financial adjustment is straightforward. The workers’ compensation insurer audits your actual wages against your declared wages, and the shortfall becomes a debt. In a business with significant casual or event-based wage spikes, that can be a large number.

Disputed claims are more serious. If a guard is injured and makes a workers’ compensation claim, and your policy was declared in a way that excluded or understated that guard’s wage category, the claim can become complicated. In the worst cases, an inadequately declared policy can be treated as non-compliant – with penalties that vary by state but can be significant.

What a Correctly Structured Policy Looks Like

For security businesses, a well-structured workers’ compensation approach starts with an accurate and comprehensive wage estimate at the outset – one that includes all employee categories, correct rate classifications, and a realistic projection of overtime and casual hours.

The risk classification for security work is higher than many other industries. Guards working in high-risk environments – event security, cash-in-transit, crowd control – carry a higher premium rate than general security. Declaring all guards under a single lower rate category is a common error that creates both compliance risk and coverage gaps.

A specialist broker who works with security companies can help you structure your wage declaration correctly at the start of the period, rather than managing a large adjustment at the end of it. They can also ensure your classification codes accurately reflect your workforce – which affects both your premium and the adequacy of your cover when a claim arises.

If your security business has grown, taken on new contract types, or significantly changed the composition of your workforce since your last renewal, now is the time to review your workers’ compensation declaration – not at adjustment time.
