Labour Hire vs Contractor vs Subcontractor: What
Labour hire vs ABN contractor vs subbie crew in Sydney 2026 — tax, IR, liability, super, sham contracting risk. Construction-specific breakdown for builders.
Three workers, same hi-vis — three completely different legal structures:
| Labour hire | ABN contractor | Subcontractor | |
|---|---|---|---|
| Who employs them | Labour hire agency | Themselves | Themselves / their business |
| Super obligation | Agency pays 12% | Worker's own SMSF | Worker's own SMSF |
| Workers comp | Agency's icare policy | Worker carries own (or deemed worker) | Worker / their insurer |
| WHS PCBU duty | Agency + host both | Head contractor + worker | Head contractor + subbie |
| Sham contracting risk | Low (PAYG) | High if controls look like employment | Low if genuine fixed-price scope |
Misclassify and you owe back-super, PAYG penalties, and — since January 2025 — face possible criminal wage theft charges.
Three workers. Same hi-vis. Same boots. On your Sydney site right now they look identical — but their legal structures aren't, and mixing them up is exposing builders to seven-figure fines under the 2025 wage theft laws.
You probably hire all three types every month. Most builders we deal with can't explain the difference clearly.
The defining test isn't what the contract says — it's what happens on site.This guide unpacks it: tax, super, workers comp, WHS duty, and IR risk. Sydney-specific. No fluff.
Labour hire — what you're actually paying for
Labour hire is straightforward. An agency employs the worker. You hire the agency. The agency invoices you per hour. The worker goes home with a payslip from the agency, not you.
Under Fair Work's labour hire framework, the agency is the legal employer. They pay PAYG, super at 12% (from 1 July 2025), workers compensation, payroll tax where the threshold is met, and leave loading.
You get an invoice. They deal with the ATO. That's the whole trade: you pay a margin over the raw wage, and in exchange the agency wears the payroll machinery and the IR risk that comes with being an employer.
The single thing builders get wrong here is treating the bill rate as "expensive labour." It isn't a wage — it's a wage plus every on-cost an employer legally carries, bundled into one number. When you compare it to a cash hourly figure, you're comparing a fully-loaded, compliant cost against a half-built one that the ATO will finish for you later.
Use labour hire when
- Demand fluctuates — a fit-out punch list needs eight TAs for three weeks, then two for a month.
- You don't have spare HR/admin — running payroll, super, and STP for a 4-person crew is a quarter-FTE job.
- You need workers fast — Leap can confirm crew by arvo for tomorrow's start.
- The work is integrated with your direct crew — same supervisor, same induction.
- You want try-before-you-hire — most deals include temp-to-perm conversion.

Labour hire = body on site, agency carries the IR risk. No PAYG, no super, no payroll tax, no workers comp, no recruiting, no sick-leave admin. Best for fluctuating demand and integrated crews.
Independent contractors — the ABN trap
This is where most builders get burnt. An independent contractor runs their own business. They have an ABN, invoice you, lodge their own BAS, and pay their own tax.
The pitch is seductive: cash to the ABN, no super, no leave, no admin. Done.
Except the ATO sees through it. From their contractor or employee guidance:
Calling them a contractor doesn't make them one. The ATO weighs the substance, not the label."Any label which you and the worker use in your contract to describe your relationship (such as 'independent contractor') will not determine or be relevant to how your relationship is characterised."
The ATO received more than 7,000 tip-offs about the building and construction industry in 2024-25. Around 20% alleged sham contracting. The whistleblower is usually a worker who didn't get paid super — or a competitor doing it right.
Genuine contractor vs sham — the on-site test
A finishing carpenter doing all the architraves in a townhouse for an agreed price, with eight other current clients and their own tools — that's a real contractor. A casual labourer working 38 hours a week under your foreman using your gear is not, no matter what's printed on the invoice.
| Signal | Genuine contractor | Sham (employee on ABN) |
|---|---|---|
| Clients | Multiple, ongoing | Only you, for months |
| Hours | Sets own within deadline | Same fixed roster daily |
| Tools | Brings own kit + vehicle | Uses yours |
| Delegation | Can send a substitute | Personally required |
| Insurance | Own PL ($10m+) | None |
| Payment | Fixed-price / per unit | Flat hourly, no quotes |
If three or more rows land in the right column, you have an employee on an ABN. Fix it before the ATO does it for you.
Subcontractors — a scope, not a body
Subcontracting is the option builders confuse most. A subcontractor is a contracting business engaged to deliver a defined scope. They run their own crew, use their own gear, and invoice on milestones or quoted lump sums — not hours-worked timesheets.
The classic Sydney subbie: a formwork crew of six who quote a project rate to set up, pour, and strip the slab of Building C. The head subbie holds the contract, pays his own crew. You pay the head subbie.
The line that trips builders up: a subbie is a business, not a person. You're buying an outcome — a poured slab, a framed level, a painted floor — and the subbie decides who turns up to deliver it. The moment you're directing individual workers in that crew, setting their hours, and paying by the hour, you've slid back into labour hire (or worse, sham contracting) wearing a subbie's invoice.
SafeWork NSW is clear: a principal contractor must be appointed for all construction projects valued at $250,000 or more — almost every job above a residential reno. As principal you must prepare a written WHS management plan, collect each subbie's Safe Work Method Statement for high-risk work, and verify their workers comp is current before they set foot on site.
Skip the WHS checks and SafeWork NSW can shut your site — and a subbie's injured worker exposes you personally under WHS Act s27.Use subbies when the work is a discrete, quotable trade package (slab, frame, plasterboard, painting) and you want price certainty. Don't when you need integration under one foreman, the scope is vague and likely to change, or you're paying day rates to dodge super — that's contracting-in-disguise.
Subbies = business-to-business deal. You're not buying labour by the hour, you're buying a deliverable. They carry super, workers comp, and PAYG for their own crew. Your job is to verify the paperwork and manage the WHS interface.
The ATO multi-factor test
This is the test that decides everything. The ATO published Taxation Ruling TR 2023/4 after the 2022 High Court decisions in Jamsek and Personnel Contracting.
The new framework: start with the contract. Where the parties wrote down their rights and obligations, those terms drive the analysis — but the substance still has to match. Six factors get weighed together:
No single factor wins. A worker can hold an ABN, invoice you, AND still be an employee if the overall picture looks like employment.
A worked example
Take Frank, a labourer, on his own ABN at a flat hourly rate, paid weekly. He works Monday to Friday under your foreman, uses your tools, has been with you 18 months, and has no other clients. Run the six factors and every one points the same way: control (foreman directs him), integration (on your crew daily), payment (hourly), tools (yours), risk (zero — paid regardless), delegation (can't send anyone else). Frank is your employee. The ABN changes nothing.
The cost of getting that one worker wrong isn't the small per-hour saving — it's back-super to day one, the Super Guarantee Charge piling interest and admin on top, the PAYG you should have withheld, and penalties of up to 75% of the unpaid tax. One misclassified labourer routinely lands as a five-figure bill.
💡 Why it matters: the contract you sign now carries far more legal weight than pre-2022. A well-drafted agreement that genuinely reflects independence gives real protection — a sloppy "contractor" contract describing employment is easier to attack now. The DIY ABN agreement off Google is genuinely dangerous.
The ATO is data-matching ABN invoicing against single-employer payments. Workers paid weekly by one entity on an ABN for 12+ months are triggering automated audits. Sydney construction is a focus sector.
Sham contracting — what it costs you
Sham contracting is telling a worker they're an independent contractor when you know — or ought reasonably to know — they're really an employee. It's covered under sections 357-359 of the Fair Work Act 2009.
Fair Work Ombudsman sets the civil penalties:
In the Personnel Contracting case (High Court 2022), a misclassified labourer was awarded $1.7m. Through 2024-25, Sydney formwork companies copped penalties between $200k and $800k for ABN-labelling de-facto employees. In March 2026 the FWO launched a joint operation with the ATO targeting construction sham contracting.
Two defences that don't work: "the worker asked for an ABN" (the Act requires you to reasonably believe it's genuine) and "I'm a small business" (there's no exemption from sham contracting).
Closing Loopholes 2024 — Same Job Same Pay
This is the legislation that changed labour hire. The Closing Loopholes Acts received Royal Assent across December 2023 and February 2024; the labour hire reforms commenced 1 November 2024.
If your business has an enterprise agreement (EA) above the award, labour hire workers on your site can apply to the Fair Work Commission for a Regulated Labour Hire Arrangement Order. If granted, you must pay them the same protected rate as a comparable direct employee — your EA rate, not the award.
The FWC won't make an order that isn't fair and reasonable; short-term work (under 3 months) and small-business hosts (under 15 employees) are excluded. By DEWR figures, 7,600+ workers have received pay rises through these orders so far — hitting large EBA head contractors first.
For most Sydney builders — under 50 staff, no EBA — Same Job Same Pay doesn't change the bill rate. But the direction of travel matters: more regulation, more pay parity, less hire-to-undercut. More in our labour hire cost breakdown.
Wage theft becomes criminal in 2025
From 1 January 2025, intentional underpayment of wages or entitlements became a criminal offence under the Fair Work Act. Fair Work Ombudsman confirms it targets deliberate non-payment — not honest mistakes.
Here's the link to today's article: if you misclassify an employee as a contractor and that results in unpaid award rates, super, or overtime, you're potentially in wage theft territory. The defence is intent — honest mistake stays civil; knowingly mislabelling someone to dodge their entitlements goes criminal.
The more obvious the misclassification, the more likely a court infers intent — a foreman directing a daily-rate ABN labourer for 18 months looks deliberate.Small businesses (under 15 employees) get one shield: the Voluntary Small Business Wage Compliance Code. Comply with it — genuine effort to understand the award, reasonable steps to pay correctly, cooperation with FWO — and you can't be referred for criminal prosecution. Bigger employers don't get the shield.
And don't count on insurance. D&O policies don't cover criminal liability, and some insurers now add wage-theft exclusions even for civil claims. Once intent is established, you're personally exposed.
Workers compensation — who carries it
This gets uniquely Sydney. NSW workers comp is run by icare, and they have a very specific view of who counts as a "worker" in construction.
Labour hire: the agency carries the policy. The premium is inside the bill rate. Done. Direct employees: you carry it — construction sits in higher-risk premium bands. ABN contractors: here's the trap.
In NSW, many construction "contractors" are deemed workers under the Workers Compensation Act 1987 — even with an ABN. Section 5 extends "worker" to cover personal-labour-for-hire arrangements. icare's guidance is explicit: if a sole-trader contractor on your site gets injured and has no own cover, your policy gets called on. Hire someone on an ABN to dodge super and you may have to insure them anyway — plus carry their third-party claims if they hold no public liability.
NSW construction lesson: never engage a solo ABN contractor without seeing their own workers comp certificate of currency AND public liability certificate. No certificates, your policy is exposed when something goes wrong.
Subbie businesses should hold workers comp in the company name, public liability (most Sydney sites require $20m), and PI if they certify anything. As principal on a project over $250k, you must verify these are current before site access — SafeWork NSW will ask to see your process during an inspection. More in host employer responsibilities under NSW law.
WHS duty — PCBU rules under labour hire
Under the WHS Act 2011 (NSW), every business that controls work on a site is a PCBU. The Act doesn't care about your contractual structure — if you're conducting work, you owe duties.
When a labour hire worker is on your site, both the agency and you are PCBUs with overlapping duties. Neither can offload to the other.
Both can be prosecuted if a worker is injured: the agency for inadequate screening, the host for site-specific hazards. Solo ABN contractors are PCBUs in their own right but also workers of your PCBU when integrated — same dual duty.
And under section 27, directors and decision-makers owe a personal due-diligence duty:
Picking the right structure for your project
After all the legal detail, here's the decision framework. There's almost never a single answer — healthy projects mix direct PAYG (your spine), labour hire (your flex), and subbies (your specialist packages). The mistake is forcing one structure across a whole job to keep the admin simple. The cheap-looking shortcut — everyone on an ABN at a flat hourly rate — is the one that fails every test in this article at once.
Think of it as matching the structure to the shape of the work, not the shape of your payroll. Steady, integrated, long-term work wants an employee. Variable, fast, integrated work wants labour hire. Defined, quotable, self-supervised work wants a subbie. Specialist, multi-client, short bursts want a genuine contractor. Most Sydney sites need all four in different corners on the same week.
Use direct PAYG when you need the worker for 2+ years of steady work, want deep loyalty and upskilling, have the HR capacity to run payroll and leave, and can absorb bench time.
Use labour hire when demand fluctuates, you need workers fast, you want try-before-you-hire, you lack HR capacity, or you want to transfer IR risk to a third party.
Use a genuine ABN contractor when the worker has multiple clients and a real business, the work is specialist (not general labour you could employ), the engagement is short and intense, and the deal is outcome-based with their own tools.
Use a subcontractor when the work is a defined, quotable trade package (frame, slab, paint, fit-out), the subbie runs their own crew, and you want to transfer the commercial risk of execution.
For a deeper look at when labour hire is actually worth it vs direct hire, we've crunched the maths on 3, 6, and 12-month engagements.
Honest disclosure — Leap is a labour hire company
Here's the bit most articles skip. Leap Labour is a labour hire company. We supply Sydney builders with labourers, trade assistants, formworkers, concreters, dogmen, riggers, and warehouse pickers — and we pay PAYG, super, workers comp, payroll tax, and leave loading on every worker.
So yes, we have skin in this game. But we wrote this straight because the alternative — builders cycling cash through dodgy ABNs to dodge super, then getting hammered by the ATO — is bad for everyone. The builders who get caught. The workers robbed of super. The honest subbies whose margins evaporate against undercutters.
Run your numbers honestly and decide. If labour hire fits, we'd love to be on your shortlist — if a real subbie or direct hire is the right answer, that's fine too. What we don't want is builders blundering into sham contracting because a podcast called ABNs a tax hack. More on why builders pick Leap and compliant labour hire in Sydney elsewhere.
The Sydney compliance checklist
Before you engage anyone next Monday — labour hire, contractor, or subbie — run this.
Then verify by structure: labour hire — agency workers comp + public liability ($20m on Sydney commercial sites) + an all-in bill rate. ABN contractors — ABN active 2+ years, multiple clients, own workers comp (NSW deemed-worker risk) and PL ($10m). Subbie crews — Pty Ltd/trust, crew workers comp, PL ($20m), WHS management plan, quoted scope, statement of no outstanding liabilities. Quarterly, re-check certificates and ticket expiries. Screenshot this and pin it to the site office wall.
If you engage Leap workers, we handle ticket verification, workers comp / PL / payroll tax / super inside the bill rate, STP lodgement, and real-time timesheets. Your job becomes the site-specific bits: induction, daily SWMS, site-hazard PPE, and managing the work. More in our Sydney labour hire transparency breakdown.
Where this is heading — 2026 and beyond
The landscape keeps moving. Three trends we're tracking that affect how Sydney builders structure their crews:
- AI-driven ATO enforcement. The ATO is shifting from manual audits to automated data-match alerts. Single-employer ABN invoicing for 12+ months now triggers risk flags automatically — "stay small and hope they don't notice" is dying.
- Same Job Same Pay extension. SJSP currently bites where the host has an EBA. DEWR consultation papers point to extension toward award-only sites on the policy roadmap — which would give labour hire workers across every Sydney site rate-parity protection.
- Workers comp deemed-worker reform. icare is reviewing the deemed-worker provisions; the ambiguity around solo construction contractors may tighten. Watch this in 2026 if you lean heavily on ABN trades.
The throughline: more regulation, more pay parity, less arbitrage. The honest structure is also becoming the only durable one.

Frequently Asked Questions
What is the actual legal difference between a labour hire worker, an independent contractor, and a subcontractor?+
A labour hire worker is employed by the agency, supplied to your site, and the agency pays PAYG, super, and workers comp. An independent contractor runs their own business under an ABN, controls their own hours, supplies their own tools, and carries their own insurance. A subcontractor is a contracting business engaged to deliver a defined scope — usually with their own crew and equipment.
Can I just call my workers contractors to avoid super and workers comp?+
No. The ATO and Fair Work look at the substance of the relationship, not the label. Sham contracting carries civil penalties up to $19,800 per breach for individuals and $99,000 for companies (2025 penalty unit rates). Serious contraventions carry higher multipliers. Labels in contracts do not determine the relationship.
What does the Closing Loopholes Act mean for hiring labour hire workers in 2026?+
If your business has an enterprise agreement (EA), labour hire workers on your site can apply through Fair Work for a Regulated Labour Hire Arrangement Order — making you pay them the same full rate as your direct employees doing the same job. Small businesses are excluded.
If I engage a subcontractor and they underpay their workers, am I liable?+
Under accessorial liability provisions, head contractors who knowingly engage subbies underpaying workers can face penalties up to $4.95 million for serious contraventions. From January 2025, intentional underpayment is also a criminal offence with up to 10 years prison.
Do I need workers comp insurance for an ABN contractor?+
Often yes. In NSW, icare treats many construction contractors as deemed workers even if they hold an ABN — meaning you must cover their workers compensation premium. If a sole-trader contractor working on your site gets injured and they have no cover, your policy gets called on.
Who is the PCBU when I use labour hire on a Sydney construction site?+
Both the labour hire agency and the host business are PCBUs (Persons Conducting a Business or Undertaking) with overlapping WHS duties. The host runs the site induction and SWMS; the agency screens tickets and provides safety equipment. Both can be prosecuted if a worker is injured.
When does a labour hire arrangement become a sham contract?+
When the worker is told they're a contractor but actually works set hours, takes direction, uses your tools, can't subcontract their work, and has no genuine business of their own. The 2024 ATO ruling TR 2023/4 lists the multi-factor test — control, integration, results, tools, risk, delegation.
