If a job ad's hourly rate doesn't clear what the award actually requires, the ad itself is illegal — not just the eventual pay. Here's how to check, and what it costs an employer who's caught.
The Legislative Ban: Section 536AA of the Fair Work Act 2009
Section 536AA of the Fair Work Act 2009 makes it illegal for an employer to advertise a job vacancy with a pay rate that falls below the statutory minimum defined by the National Minimum Wage Order or the applicable Modern Award covering that role. This matters at the advertising stage itself, before you've even applied — the ad doesn't need to have actually resulted in underpayment yet to be a violation.
Prohibited advertising practices include:
- Advertising a flat hourly rate that breaches applicable award penalty rates — for example, advertising $20/hour for weekend work when the relevant award requires $30/hour for that shift.
- Posting vacancies offering cash-in-hand rates below statutory minimums.
- Advertising piecework or commission-only rates that fail to guarantee at least the base minimum award equivalent under the statutory safety net.
As a practical reference point, the National Minimum Wage as of 1 July 2026 is $26.44 per hour or $1,004.90 per week — but most roles are covered by a specific Modern Award with its own, often higher, minimum rates and penalty loadings, so the award rate — not the bare National Minimum Wage — is usually the real floor to check against.
Enforcement and Penalties
The Fair Work Ombudsman actively monitors recruitment job boards — Seek, Indeed, Gumtree, and social media platforms — specifically to identify illegal wage advertising.
Penalties for advertising below minimum wage: employers who post non-compliant pay rate advertisements face civil pecuniary penalties enforced by the federal courts under Section 539 of the Fair Work Act 2009. Following the February 2024 penalty reforms, the maximum penalties for a standard contravention are $18,780 for an individual and, for a body corporate that isn't a small business, five times the individual maximum — a structure that scales penalties up sharply for larger employers rather than applying a single flat cap. Serious contraventions carry substantially higher maximums again. These figures are also indexed periodically via the Commonwealth penalty unit value, which itself increased from $330 to $364 on 1 July 2026 — so it's worth checking the current figure rather than assuming a number from an older source remains exact.
What This Means for You
Before applying to a job, check the advertised rate against the actual Modern Award that covers the role using the Fair Work Ombudsman's Pay and Conditions Tool — an ad that looks reasonable at first glance can still be below what the specific award requires for that role, shift type, or your age bracket. If you spot a clearly non-compliant ad, you can report it directly to the FWO, and if you've already worked at an underpaid rate, the same underpayment recovery paths apply as for any other wage dispute.
Generate a formal demand letter if you were paid below the rate that should have applied to your role.
