A contractor agreement looks simpler than employment — no payroll tax, no super, no leave entitlements, no Fair Work termination process. That apparent simplicity is exactly why it goes wrong. The Fair Work Act 2009 has explicit anti-sham contracting provisions. The ATO uses substance-over-form tests for super and PAYG. The Federal Court has issued landmark decisions (Personnel Contracting, Jamsek) reframing how contractor relationships are characterised.
Get it wrong and the contractor was actually an employee — meaning back-pay of leave, super, payroll tax, plus penalties. Get it right and you have a clean, enforceable arrangement.
The clauses that matter most
- Substance of the relationship. Is the contractor genuinely running their own business, or just an employee dressed up as a contractor? Multiple-factor test: control over how work is done, ability to delegate, provision of own tools, financial risk, integration into the business. The contract is one factor among many — but the contractual terms strongly influence the substance.
- Right of substitution. Can the contractor send someone else to do the work? Genuine contractors can; employees can’t. A meaningful substitution clause is one of the strongest contractor indicators.
- Payment basis. Per task, per project, per output, or per hour? Per-output payment is more contractor-like; pure hourly with no scope deliverable looks like employment.
- Superannuation Guarantee. Contractors who work primarily for their labour are deemed employees for super purposes under section 12(3) of the SGAA — even if they’re genuine contractors for every other purpose. Either pay super or document why the deeming provision doesn’t apply.
- IP ownership. Default rule: copyright in works created by a contractor belongs to the CONTRACTOR, not the engaging party. To get IP, you need an explicit assignment clause. Without it, you’ve paid for work you can only use, not own.
- Insurance. Contractor’s own public liability and professional indemnity insurance — minimum levels specified, certificates required. Workers comp may also apply depending on state and substance of arrangement.
- Termination. Notice period, payment for work in progress, return of materials. Without a notice clause, either party can terminate at any time — usually fine, sometimes problematic.
- Restraint and confidentiality. Reasonable restraints (limited duration, geography, scope) and confidentiality obligations are enforceable. Excessive restraints will be struck down.
Common red flags
- “Contractor” who works full-time for one engager, on the engager’s premises, with the engager’s tools, supervised by the engager — almost certainly an employee in substance
- Hourly rate with no scope deliverable — looks like wages
- No right of substitution — strong employee indicator
- “Contractor must comply with all company policies” — too much control, looks like employment
- No IP assignment clause — engager doesn’t own what they paid for
- Super not paid and no documented analysis of section 12(3) SGAA
- Contractor invoices identical amount each fortnight rounded to “salary equivalent” — paper trail screams sham contracting
- Restraint clauses that would prevent the contractor servicing other clients in the same field

When to take it to a lawyer
For arrangements where the contractor is engaged on a near-full-time basis, multi-year contractor engagements, arrangements with international contractors (PE risk, withholding tax), or any case where you’re considering converting employees to contractors — engage an employment lawyer or tax adviser. The Personnel Contracting and Jamsek decisions changed the landscape; the safe path is professional advice.
The Personnel Contracting / Jamsek shift
In 2022 the High Court of Australia handed down two decisions — CFMMEU v Personnel Contracting and ZG Operations v Jamsek — that reframed how contractor relationships are characterised. Before these decisions, courts looked at the “totality of the relationship” including how the parties actually behaved over time. After these decisions, the contract is dispositive provided it isn’t a sham — meaning the written agreement carries much more weight than the day-to-day practice. The practical implication: a well-drafted contractor agreement that creates a genuine contractor relationship on paper is now significantly more defensible. A poorly-drafted agreement that contradicts the actual working arrangement is more vulnerable. The contractor agreement review now matters more than it did three years ago.
