Contractor or employee: the Australian guide

Getting this wrong is expensive, and it is expensive in a way that compounds quietly. Backpay, superannuation with interest on top, and a sham contracting exposure that has become harder to defend since 2024.

This guide covers what actually decides the question in Australia, the second test most businesses have never heard of, and what belongs in a contractor agreement that holds up.

1. Why the label doesn't decide it

A contract can call someone an independent contractor on every page. They can have an ABN, issue invoices, and describe themselves that way on their own website. None of that decides the question.

Australian law looks at the relationship, not the paperwork. If the working reality is employment, the person is an employee - with leave, notice, unfair dismissal rights and superannuation - regardless of what the document says.

That has always been broadly true, but the balance between the contract and the reality shifted twice in three years, and it now sits firmly on the side of reality.

2. The test: real substance, practical reality and true nature

What changed

In 2022, two High Court decisions moved the test towards the written contract. Where a comprehensive written agreement existed, the terms of that agreement largely determined the relationship, and the way the parties actually behaved mattered much less.

Parliament reversed that. Section 15AA of the Fair Work Act 2009 (Cth) commenced on 26 August 2024 and requires the relationship to be assessed on its "real substance, practical reality and true nature". It is often called the whole-of-relationship test, because it looks at the contract and how the contract is performed in practice.

What gets weighed

No single factor is decisive. The assessment looks at the relationship as a whole, and the questions that carry the most weight are these.

• Control. Who decides how the work is done, when it is done, and in what order? A contractor typically controls their own method. An employee is directed.

• Commercial risk. Who wears it if the job goes wrong or takes longer than expected? A contractor carrying no risk of loss looks a lot like an employee.

• Delegation. Can the person send someone else to do the work? A genuine right to delegate - one that is real rather than written - points strongly towards a contract for services.

• Tools and equipment. Who supplies them, and who pays for them?

• Integration. Does the person present as part of your business, or as their own? Uniforms, business cards, an internal email address and a place on the org chart all point one way.

• Hours and continuity. Set hours, ongoing work and an expectation that the arrangement continues indefinitely all lean towards employment.

• Business of their own. Do they work for others? Do they advertise, quote, and carry their own insurance? Someone with a single client and no independent business is closer to an employee than to a contractor.

What the contract still does

The written agreement has not stopped mattering. It is the starting point, and where the practical reality is genuinely ambiguous, the contract can settle it.

What it can no longer do is override a reality that points the other way. A contract describing a right to delegate that nobody has ever used, in a role where delegation would never be accepted, carries very little weight.

The practical implication: the agreement and the working arrangement need to match. A well-drafted contractor agreement that describes an arrangement you don't actually operate is worse than useless, because it evidences the gap.

3. The second test: superannuation

This is the part most businesses miss, and it catches genuine contractors.

Australia runs two independent tests. Passing the first one does not answer the second.

The labour test

Superannuation runs on the Superannuation Guarantee (Administration) Act 1992 (Cth). Under s 12(3), a person engaged wholly or principally for their labour is treated as an employee for superannuation purposes - even where they are a genuine independent contractor under employment law.

So a person can be correctly classified as a contractor, with no entitlement to leave or notice, and still be owed superannuation.

The question is what the contract is for. A contract for a person's own labour engages s 12(3). A contract for a result, or one where the person supplies substantial plant and equipment, or one performed by the person's own team, generally does not.

Who is most exposed

The engagement most likely to fall inside s 12(3) is an individual, working largely alone, paid for their time rather than for a defined deliverable. Consultants. Tradespeople engaged without their own crew. Freelancers on a day rate.

An ABN makes no difference. Neither does an invoice. Neither does a clause saying superannuation is not payable - parties cannot contract out of the superannuation guarantee.

What it costs when it's missed

Unpaid superannuation is not settled by paying the original amount late. It becomes the superannuation guarantee charge, which has three parts:

• the shortfall amount

• nominal interest, at 10% a year

• an administration component of $20 per employee, per quarter

Unlike an ordinary contribution, the charge is not tax deductible. The shortfall is also calculated on salary and wages, a broader base than the ordinary time earnings used for a normal contribution - so the amount owing can exceed what a simple recalculation would suggest.

Why offshore tools miss it

A contract system built on US 1099 rules or UK IR35 logic has no concept of s 12(3). Those regimes have nothing equivalent. The engagement passes every check the tool knows how to run, and the exposure sits there accruing.

This is one of the clearest cases where using a tool built for another country produces a confident answer that is wrong.

4. Sham contracting

Section 357 of the Fair Work Act 2009 (Cth) prohibits representing an employment relationship as an independent contracting arrangement.

The defence used to turn on whether the employer honestly believed the arrangement was a contract for services. It now requires the employer to show that belief was reasonable.

That is a materially higher bar. An employer who never asked the question, never took advice, and never looked at how the work was actually performed will struggle to show a reasonable belief - particularly where the arrangement looks like employment on its face.

Related provisions also matter. The Fair Work Commission has a jurisdiction to deal with unfair contract terms in services contracts, and the Independent Contractors Act 2006 (Cth) applies to engagements above the contractor high income threshold, which changes each 1 July.

5. What a defensible contractor agreement contains

A contractor agreement cannot make an employee into a contractor. What it can do is describe a genuine contracting arrangement accurately, so that the document and the reality support each other.

Scope of work

Define the result, not the hours. A contract to deliver a defined outcome reads as a contract for services. A contract to be available for 38 hours a week reads as employment.

Be specific about what is being delivered, to what standard, and by when.

Delegation

If the person can genuinely subcontract or send a substitute, say so - and mean it. A delegation clause that has never been exercised, in a role where you would refuse a substitute, works against you rather than for you.

Payment

Payment against milestones or deliverables supports a contracting characterisation. An hourly or daily rate paid on a regular cycle looks like a wage, particularly where it continues regardless of output.

Set out how invoices are submitted, what triggers payment, and what happens if work is defective.

Equipment, insurance and business status

Record who supplies tools, equipment and materials. Require the contractor to hold their own insurance where that is appropriate to the work, and to maintain their own business registrations.

These are not decisive on their own, but a contractor supplying nothing and insured by nobody but you is a weak arrangement.

Term and termination

A contract with no end date, terminable on notice, resembles employment. A term tied to the completion of the work, with defined termination rights, does not.

Superannuation

Deal with it explicitly rather than by denial. If the engagement is principally for the person's labour, superannuation is payable and the contract should account for it in the rate. A clause simply stating that no superannuation is payable does not change the obligation.

Intellectual property

See section 6 - this needs its own attention.

Confidentiality and restraint

A contractor with access to confidential information should be bound to protect it, and that obligation should survive the end of the engagement.

Restraints on contractors are subject to the same restraint of trade doctrine that applies to employees. They must be reasonable in duration, area and restricted activity to be enforceable, and the applicable state law matters - New South Wales allows a court to read an unreasonable restraint down under the Restraints of Trade Act 1976 (NSW) s 4(3), while other states are more likely to strike it out entirely.

6. Who owns the work

This is the clause businesses most often assume they don't need, and most often wish they had.

Under the Copyright Act 1968 (Cth), copyright in work created by an employee in the course of their employment generally belongs to the employer by default. Copyright in work created by an independent contractor generally belongs to the contractor, unless the contract assigns it.

That means a designer, developer, writer or consultant you engaged and paid may own the copyright in what they produced for you. You may have an implied licence to use it for the purpose it was commissioned for, but a licence is not ownership - and it may not cover reuse, modification, or a later sale of the business.

A contractor agreement that does not deal with intellectual property leaves this open. The fix is straightforward: a written assignment of the intellectual property in the deliverables, effective on creation or on payment, with a moral rights consent where appropriate.

The time to fix it is before the engagement. Afterwards, you are asking someone to sign away something they already own.

7. The clauses that cause the most trouble

• "The contractor is not an employee." A statement of characterisation, not a fact. It carries almost no weight against a working reality that says otherwise.

• "No superannuation is payable." Cannot displace s 12(3).

• A delegation clause nobody uses. Actively unhelpful, because it evidences the gap between the document and the reality.

• Set hours and a fixed weekly payment. The two strongest indicators of employment, and they frequently appear in agreements titled "Independent Contractor Agreement".

• Silence on intellectual property. The default runs against you.

• An overreaching restraint. A five-year, Australia-wide restraint on a contractor is unlikely to be defensible, and in some states an unreasonable restraint fails altogether rather than being narrowed.

• Indefinite term, no deliverables. If the contract cannot say what is being delivered, it is describing a job.

8. When this needs a lawyer

Some of this can be worked through from the document. Some of it cannot, and it is worth knowing which is which.

Get advice from an Australian legal practitioner where the classification is genuinely borderline and the engagement is significant. Where a contractor has been engaged for a long period on terms that look like employment and you are considering changing the arrangement. Where a contractor has raised a claim, or a regulator has made contact. Where the engagement sits above the contractor high income threshold and the Independent Contractors Act 2006 (Cth) may apply. And where the work involves valuable intellectual property and the ownership position is unclear.

The common thread: these turn on facts, history and conduct rather than on the words in the document - which is precisely where a contract analysis, however thorough, stops being able to help.

9. Before you engage: a checklist

About the work

• Is there a defined deliverable, or is this a role?

• Who controls how and when the work is done?

• Who wears the risk if it goes wrong?

• Can the person genuinely send someone else?

• Who supplies the tools, equipment and materials?

About the person

• Do they work for other clients?

• Do they have their own insurance and business registrations?

• Will they present as part of your business, or as their own?

About the money

• Is payment tied to deliverables, or to time?

• Is the engagement principally for their labour? If so, superannuation is payable.

• Has superannuation been accounted for in the rate?

About the document

• Does the agreement describe the arrangement you will actually operate?

• Is intellectual property assigned in writing?

• Are confidentiality obligations expressed to survive the engagement?

• Is any restraint reasonable in duration, area and activity, and drafted for the right state?
