Probation Periods for Employers: Legal Requirements & Best Practice

There is no legal maximum or minimum probation period under the Fair Work Act—you decide. However, 3–6 months is industry standard and best practice. A 3-month period is sufficient to assess performance and cultural fit for most roles. A 6-month period aligns with the new unfair dismissal threshold from 1 January 2027, when employees gain protection after just 6 months of service. Probation periods longer than 6 months are less common and may be scrutinized as unreasonable. Always include the probation length in the written employment contract.

Yes, you can dismiss a probationary employee, but the dismissal must still be fair, substantively justified, and procedurally compliant. Probation does not exempt you from the Fair Work Act. You must have documented reasons (poor performance, misconduct, or genuine business need), you must have given the employee a fair opportunity to improve or respond, and you must follow proper dismissal procedures (meeting, explanation, listening to their response). Sudden dismissal without warning or documentation is likely to be found unfair by the FWC, even during probation.

You can extend a probation period, but only with the employee’s written agreement. You cannot unilaterally extend probation—that changes the contract and requires consent. If performance is poor, discuss an extension with the employee and document their agreement in writing, or make a dismissal decision during the original probation period. Repeatedly extending probation without agreement or final decision looks deliberate and unfair and will not be tolerated by courts or the FWC.

From 1 January 2027, employees will gain unfair dismissal protection after just 6 months of service, not 2 years (except for small businesses and certain grounds). This means a 3-month probation plus 3 months post-probation = 6 months of full legal protection. A 6-month probation aligns with the new threshold, ending just as FWC protection kicks in. If you currently use long probation periods (12+ months) to delay unfair dismissal exposure, that strategy becomes less effective from January 2027. Focus instead on fair procedures and documented performance management throughout the employment.

Document everything: (1) At hire—written contract with probation length, job description, KPIs, induction checklist, conduct expectations. (2) During probation—30-day check-in notes, mid-probation formal review with written feedback, any verbal warnings or improvement notices, incident reports for misconduct or underperformance. (3) At probation end—final written review against original KPIs, pass/fail decision, and if dismissing, written notice citing specific performance/conduct reasons with reference to documentation. A simple probation tracker (spreadsheet) logging check-ins and feedback is invaluable in an FWC hearing.

No. Personality clash or perceived ‘culture fit’ alone do not justify dismissal. You must have documented performance or conduct issues. Culture fit is subjective and, without objective performance reasons, looks like discrimination or unfair treatment. If an employee is not performing their duties, not following policies, or not meeting agreed KPIs, that’s a documentable reason. But if their work is satisfactory and their conduct is appropriate, culture fit concerns are not a legal justification for dismissal.

Probation is an agreed initial period (typically 3–6 months) where a new permanent employee is assessed for suitability. It’s part of the hiring process. Performance management is an ongoing process throughout employment where managers provide feedback, set goals, and address underperformance. Probation includes early assessment; performance management is continuous. After probation ends, you still manage performance—probation does not end your responsibility to give feedback and support. A poorly performing probationary employee should receive feedback during probation, just like a poor-performing permanent employee during performance management.

Modern Awards don’t override probation rules, but they may set minimum standards for notice periods, redundancy, or consultation. Some awards specify that probation periods cannot exceed 6 months. Always check the relevant Modern Award for your industry. Dismissal during probation must still comply with the award’s notice and consultation requirements where applicable. Fair Work Ombudsman and the FWC website have searchable award databases. If your award and probation terms conflict, the award applies.

If an employee is not meeting expectations, start by giving them feedback and a fair opportunity to improve. During the final weeks of probation, hold a formal review meeting discussing their performance against the original KPIs. If they’ve not improved and you decide to dismiss, give written notice citing specific performance or conduct reasons and referencing your documented feedback and reviews. Explain the decision clearly, give them a chance to respond, and provide written confirmation of the dismissal with the effective date and any entitlements due (final pay, accrued leave). Ensure the process is fair and well-documented—even during probation, an unfair dismissal claim can land you in the FWC.

A probation period is an agreed initial period in a permanent employee’s employment where both employer and employee can assess fit and performance. Under Australian law, there is no legal definition—it’s an agreed arrangement. Probation applies only to permanent employees (full-time and part-time), not casuals. Probationary employees have the same legal rights as permanent employees, including unfair dismissal protection (once they meet the qualifying period), but employers have slightly more flexibility in assessing suitability before confirming permanence.
