A letter of resignation is a formal written notice from an employee to their employer communicating the employee’s decision to end their employment and providing the notice period required by their employment contract, Modern Award, Enterprise Agreement, or the National Employment Standards (NES) under the Fair Work Act 2009 (Cth). It is the standard and professionally expected mechanism for resigning from employment in Australia and forms part of the employee’s permanent employment record.

In Australia, employment is governed primarily by the Fair Work Act 2009 (Cth), which establishes the national workplace relations system covering most private sector employees. The National Employment Standards (NES) in Part 2-2 of the Fair Work Act set the minimum entitlements that apply to all national system employees, including minimum notice periods, annual leave, personal/carer’s leave, long service leave access, superannuation, and other rights. State and territory public sector employees may be covered by separate state legislation.

The NES minimum notice periods that reflect what an employee is expected to give on resignation are: 1 week for less than 1 year of continuous service; 2 weeks for 1 to 3 years; 3 weeks for 3 to 5 years; and 4 weeks for more than 5 years of continuous service. An additional 1 week applies where the employee is over 45 years old and has completed at least 2 continuous years of service with the employer. In practice, employment contracts and Modern Awards (particularly for professional or senior roles) often specify longer notice periods. The contract or award provision takes precedence over the NES minimum if it is more favourable to the employee.

A letter of resignation should be written professionally, even if the circumstances of the resignation are difficult. It is a permanent document that becomes part of the employment file and may be referred to if the employee seeks a reference from the employer in future. Australian employment law does not require an employee to state a reason for resigning, but including a brief, positive statement can help maintain goodwill. The letter should clearly state the effective date of resignation and the last working day, make clear whether the employee is working through the notice period or offering an alternative arrangement, and address practical matters such as handover, return of company property, and final entitlements.

A letter of resignation is needed whenever an employee in Australia wishes to formally end their employment relationship. Providing written notice of resignation is the expected professional standard and protects both the employee and the employer by creating a clear record of the date on which notice was given and the agreed last working day.

Under the Fair Work Act 2009 (Cth) and its associated instruments, the failure to give adequate notice may have financial consequences. If an employee does not give the required notice, the employer may be entitled to deduct an amount from the employee’s final pay equivalent to the notice shortfall, subject to any applicable terms in the employment contract or Modern Award. Section 324 of the Fair Work Act provides the circumstances in which lawful deductions from pay may be made.

A resignation letter is particularly important where: the employee has a lengthy contractual notice period (1–3 months is common for professional and managerial roles) and needs to give formal written notice to trigger the period precisely; the employee is resigning for cause (for example, following a serious breach of contract by the employer, constructive dismissal, or a significant change to their role or location); the employee wants to protect their rights to final entitlements (annual leave payout under section 90 of the Fair Work Act, accrued long service leave, and outstanding superannuation contributions); and the employee intends to seek a reference from the employer and wishes to leave on good terms.

A well-drafted resignation letter also provides clarity about handover arrangements, which is particularly important in industries where the transfer of knowledge, client relationships, or access credentials requires careful planning. For employees in regulated industries (such as financial services, healthcare, or education), clear resignation documentation is important for regulatory compliance and licensing records.

Long service leave eligibility is another consideration. In most Australian states and territories, long service leave entitlements accrue after a specified period (7–10 years depending on the jurisdiction) and a pro-rata entitlement may apply on resignation after a shorter qualifying period. The rules vary by state: the Long Service Leave Act 1955 (NSW), the Long Service Leave Act 2018 (Vic), and equivalent legislation in each state and territory set the applicable rules. A resignation letter that clearly records the last working day helps ensure that long service leave entitlements are correctly calculated.

A professional and legally effective Australian letter of resignation should contain several key elements that ensure the notice is clear, enforceable, and protects the employee’s rights under Australian employment law.

The date of the letter should be clearly stated, as this is the date from which the notice period is calculated. If the resignation is delivered by email, the timestamp of the email serves as the official delivery date. If delivered in person, keeping a copy with a received stamp or confirmation of delivery is advisable.

The formal resignation statement must unambiguously state the employee’s intention to resign from their named position and state the effective date of the resignation. It should also state the last working day after the notice period has expired. This removes any ambiguity about when the employment ends.

The notice period must be correctly calculated in accordance with the employment contract, applicable Modern Award or Enterprise Agreement, and the NES. The NES notice periods are: less than 1 year of service — 1 week; 1 to 3 years — 2 weeks; 3 to 5 years — 3 weeks; over 5 years — 4 weeks; plus 1 additional week if over 45 with 2+ years of continuous service. Contractual or award notice periods that are longer than the NES minimum will prevail. Specifying the notice period in the letter avoids disputes about the calculation of the last working day.

The final entitlements request should reference the statutory obligations. Under section 90(2) of the Fair Work Act 2009 (Cth), accrued but untaken annual leave must be paid out on termination at the ordinary time rate. The letter should specifically request payment of accrued annual leave, and should also address any outstanding long service leave entitlements under applicable state or territory legislation. It should note that superannuation contributions under the Superannuation Guarantee (Administration) Act 1992 continue until the last day of employment.

The handover commitment demonstrates professionalism and goodwill. Describing what the employee will do during the notice period to ensure a smooth transition — completing outstanding projects, preparing handover notes, briefing colleagues — helps maintain a positive relationship with the employer and supports a positive reference.

The return of company property section confirms the employee’s intention to return all company assets — laptops, access cards, mobile phones, confidential documents, and other property — on or before the last working day. This addresses a common source of disputes on separation and may be required by the employment contract or IT security policies.

A professional closing that expresses good wishes for the employer and colleagues helps end the employment relationship on a positive note and supports the likelihood of a favourable reference.
