Construction Recruitment Costs Explained: Job Boards, Agencies and Labour Hire Compared

Recruitment is a cost of doing business in construction but it is a cost that most employers do not examine carefully until something has gone wrong. Either a role has taken far too long to fill, an agency fee has arrived that was larger than anticipated, or the labour hire bill at month-end looks very different to the mental estimate made at the start of the project.

Understanding what each recruitment channel actually costs and what it delivers in return is not a complex exercise, but it is one worth doing. The difference between informed channel selection and defaulting to habit can represent thousands of dollars per hire and significantly different outcomes for the business.

The Three Main Channels

Construction employers in Australia typically access their workforce through three primary channels: job board advertising, recruitment agencies and labour hire. Each has a different cost structure, a different risk profile and a different set of circumstances it is best suited to.

Job Board Advertising: Cost and What It Delivers

Job board advertising is the most straightforward cost to understand. An employer pays a fixed fee to list a role for a defined period. Applications come in. The employer reviews, shortlists and hires directly. There is no percentage of salary, no ongoing margin on the worker's wages and no additional cost once the role is filled.

On generalist employment platforms, standard listing costs in Australia range from approximately $200 for a basic listing to over $800 for premium placement with additional features. These costs provide broad exposure across the platform's general audience.

Specialist construction job boards operate at similar or lower price points while delivering a more targeted, industry-specific audience. As covered in Why Industry Specific Job Boards Still Work in 2026, the value of a specialist platform is not primarily about lower cost it is about the relevance of the audience reached. Fewer irrelevant applications means less screening time, which represents a real saving in management resource even when the listing cost is comparable.

The limitation of job board advertising is that it is passive. The employer lists the role and waits for candidates to find it. In a market where the most capable workers are already employed and not actively searching, advertising alone may not reach the full candidate pool available.

Typical cost per hire via job board advertising: Listing fee ($200–$800) plus internal management time. For roles that produce a hire quickly, this is consistently the lowest-cost channel.

Recruitment Agencies: Cost and What They Deliver

Recruitment agencies provide a managed hiring service. Depending on the role, they may handle sourcing, advertising, screening, shortlisting and candidate communication, with the employer receiving a more focused group of candidates to interview and select from.

The value is usually in time saved, market knowledge and access to candidates who may not respond to a standard job ad. For specialist, senior or hard-to-fill construction roles, a good agency partner can be a practical option.

Agency fees are commonly charged as a percentage of the placed worker’s annual salary. In construction, this can vary depending on the role, seniority, urgency and terms agreed. For employers, the key point is not just the fee itself, but whether the role justifies a managed recruitment process.

The agency model can make sense when the role is difficult to fill through advertising alone, when the employer lacks the time to manage the full hiring process, or when speed and candidate access are more important than the lowest possible cost-per-hire.

For recurring trade, labour or site-based roles, employers may also want to consider whether building a direct candidate pipeline over time would create better long-term value.

Typical cost structure: percentage-based placement fee, usually tied to the successful hire.

Labour Hire: Cost and What It Delivers

Labour hire is a different commercial model to both job boards and recruitment agencies. Rather than facilitating a direct hire, a labour hire company employs the worker and supplies them to the client business on an agreed hourly bill rate.

That bill rate usually covers the worker’s wage, superannuation, workers compensation, payroll administration, compliance costs and the provider’s margin.

The value of labour hire is flexibility. Employers can bring workers onto a project quickly, cover short-term gaps, manage fluctuating project phases and reduce the internal administration involved in directly employing every worker.

For short-term requirements, emergency coverage or project phases where headcount is expected to change, that flexibility can represent genuine value.

Where employers need to think carefully is when labour hire becomes the default option for ongoing or long-term roles. Over time, the premium paid for flexibility can become a significant cost, especially where the same role could potentially be filled through direct employment.

The other consideration is workforce continuity. Workers supplied through labour hire may do excellent work on site, but the employment relationship sits with the labour hire provider. For employers trying to build a stable internal team, direct employment or candidate sourcing may create stronger long-term value.

As discussed in our article on Candidate Sourcing vs Labour Hire, the strongest approach is often not choosing one model permanently. Labour hire, job advertising, recruitment agencies and direct candidate sourcing all have a place. The key is using each model deliberately based on the role, timeframe, urgency and commercial outcome required.

Typical cost structure: hourly bill rate covering wages, employment on-costs, administration and provider margin.

Introduction-Based Sourcing: An Alternative Cost Model

A fourth option sits between the agency model and direct employment: introduction-based candidate sourcing. This involves a specialist identifying and introducing pre-screened candidates to the employer, who then employs the worker directly. The sourcing fee is a one-off charge rather than a percentage of ongoing salary or an hourly margin.

CJ Recruitment Global operates on this model for construction, civil and mining employers providing qualified candidate introductions for roles where advertising has not produced sufficient results, without the ongoing cost structure of labour hire or the standard agency percentage model.

For employers filling permanent or long-term roles, this model typically produces a lower total cost per hire than either a traditional agency engagement or extended labour hire dependency.

How to Choose the Right Channel

The most effective approach for most construction employers is not to select a single channel and apply it universally it is to match the channel to the role, the urgency and the cost tolerance of the business.

A useful decision framework:

Use job board advertising when the role is well-defined, the candidate pool is reasonably accessible and there is enough lead time for applications to come in. Advertising through a specialist construction platform is more likely to produce relevant results than a generalist board for most construction, civil and mining roles.

Use agency sourcing when the role is senior or specialist, when internal time to manage the process is genuinely limited, or when the position is urgent and the agency's existing candidate relationships can compress the timeline. Negotiate the fee structure before the search begins.

Use labour hire for short-term requirements, variable headcount phases and emergency gap coverage where flexibility genuinely outweighs the premium cost. Be cautious about using it as the default for ongoing or permanent roles.

Use introduction-based sourcing when advertising alone has not produced the right candidates, when the role requires proactive market access rather than passive inbound, and when the employer wants to establish a direct employment relationship without paying ongoing margins.

The Cost of Doing Nothing

No comparison of recruitment channel costs is complete without accounting for the cost of leaving a role vacant. As examined in detail in The Cost of Leaving Construction Roles Unfilled, the cumulative cost of vacancy across overtime, labour hire dependency, delay risk and retention impact consistently exceeds the cost of a proactive, well-targeted recruitment approach.

The goal is not to minimise what is spent on recruitment in isolation. It is to minimise the total cost of filling roles which means accounting for what vacancy costs alongside what each channel charges.
