Salary Increment Letter (Australia)

A Salary Increment Letter in Australia sets out the duties, hours, pay, leave, and termination terms between employer and employee, consistent with the minimum entitlements guaranteed by the Fair Work Act 2009 (Cth).

The legal framework governing salary adjustments in Australian workplaces is primarily the Fair Work Act 2009 (Cth). Under Section 202 of the Fair Work Act 2009, any variation to an individual flexibility arrangement (IFA) must be documented in writing and signed by the employer and employee. For standard employment contracts, a salary increase agreed between the parties constitutes a variation to the employment contract, and written documentation provides clear evidence of the new terms.

All salary increases must comply with the minimum wage requirements established under the Fair Work Act 2009 (Cth). The Fair Work Commission conducts an Annual Wage Review each year, with increases to Modern Award minimum wages typically taking effect from 1 July. Employers must require that the new salary meets or exceeds the applicable Modern Award rate for the employee's classification. The Fair Work Ombudsman (FWO) has broad enforcement powers under Section 539 of the Fair Work Act 2009 to investigate underpayment complaints, issue compliance notices, and commence civil penalty proceedings. Civil penalties for underpayment can reach $93,900 per contravention for corporations.

Superannuation implications are a critical element of any salary increase in Australia. The Superannuation Guarantee (Administration) Act 1992 (Cth) requires employers to pay the Superannuation Guarantee — currently 11.5% of ordinary time earnings for the 2024-25 financial year, rising to 12% from 1 July 2025 — into the employee's nominated superannuation fund. An increase in base salary automatically increases the employer's superannuation guarantee obligation. The Australian Taxation Office (ATO) administers the Superannuation Guarantee and can impose a Superannuation Guarantee Charge under the Superannuation Guarantee Charge Act 1992 (Cth) on employers who fail to make correct contributions. Section 535 of the Fair Work Act 2009 (Cth) requires national system employers to maintain employee records, and regulation 3.33 of the Fair Work Regulations 2009 specifies that pay records must include the rate of pay. The Privacy Act 1988 (Cth) and the Australian Privacy Principles govern the handling of employee personal information including salary data. The forms-legal.com Salary Increment Letter (Australia) template is drafted to comply with the Fair Work Act 2009 (Cth) and the National Employment Standards (NES).

An employer should issue a Salary Increment Letter in Australia whenever an employee's base salary is increased, regardless of the reason for the increase. Common triggers include completion of a probationary period, an annual performance review resulting in a pay rise, a market salary realignment to retain a key employee, a promotion to a higher role classification, a cost-of-living adjustment, or the outcome of a Modern Award annual wage review that requires a minimum wage increase.

The letter is particularly important where the employee's employment contract specifies a salary review process or requires written notification of any change to remuneration. Failure to issue a written increment letter in these circumstances may constitute a breach of the employment contract, exposing the employer to a general protections claim under Part 3-1 of the Fair Work Act 2009 (Cth) if the employee believes the failure to document the change was connected to the exercise of a workplace right.

Where the salary increase brings an employee's remuneration above the high-income threshold — $175,000 per annum for the 2024-25 financial year under the Fair Work Act 2009 — the employer may wish to consider whether a high-income guarantee should be included in the increment letter to preserve certain award-free status arrangements. The Fair Work Commission sets the high-income threshold annually under section 333 of the Fair Work Act 2009.

For employees covered by an enterprise agreement made under Part 2-4 of the Fair Work Act 2009, any salary adjustment must comply with the agreement's terms. The Fair Work Commission registers enterprise agreements and any variation to an in-force agreement requires formal approval under Division 7 of Part 2-4. The increment letter should confirm whether the increase is consistent with the enterprise agreement or is a separately negotiated over-award payment.

The letter should be issued before the new salary takes effect — not retrospectively — and both the employer and employee should retain a signed copy as part of the employment record. The Fair Work Ombudsman recommends that employment records including salary documentation be retained for seven years under the Fair Work Regulations 2009. Issuing a properly documented increment letter reduces the risk of underpayment disputes before the Fair Work Commission or the Federal Court of Australia, and provides clear evidence if the employee later brings a claim under section 323 of the Fair Work Act 2009 relating to the method and frequency of payment.

A Salary Increment Letter for an Australian employee must include the following elements to be legally effective and compliant with the Fair Work Act 2009 (Cth) and the National Employment Standards (NES).

Employer and employee details: The employer's full legal name and ABN; the employee's full name, job title, and department; and the date of the letter.

Current and new salary: The employee's current annual base salary (gross, expressed in AUD, exclusive of superannuation); the new annual base salary from the effective date; the percentage or dollar amount of the increase; and whether the salary is expressed as an annualised salary, an hourly rate, or a total remuneration package inclusive of superannuation.

Effective date: The specific date from which the new salary applies — typically the first day of the next pay period following the review date — to ensure accurate PAYG withholding calculations by the Australian Taxation Office (ATO) and correct Single Touch Payroll (STP) reporting under the Taxation Administration Act 1953 (Cth).

Superannuation update: Confirmation of the updated employer superannuation guarantee contribution at 11.5% (2024-25) of the new ordinary time earnings, calculated under the Superannuation Guarantee (Administration) Act 1992 (Cth), and the nominated superannuation fund details where relevant.

Conditions of the increase: Whether the increment is unconditional or subject to conditions such as maintaining performance standards, completing a training requirement, or remaining employed for a specified period. Conditional increments should be carefully drafted to avoid creating a contractual entitlement before the condition is satisfied.

Award and NES compliance confirmation: A statement confirming the new salary meets or exceeds the applicable Modern Award minimum rate for the employee's classification and employment type under the Fair Work Act 2009 (Cth), that all National Employment Standards entitlements under Part 2-2 of the Fair Work Act 2009 (Cth) are maintained, and that the increase does not trigger any variation to the employee's NES entitlements (such as annual leave loading calculated under Section 90 of the Fair Work Act 2009 (Cth)).

Continuity of other terms: A statement that all other terms of the employment contract remain unchanged. This prevents any ambiguity about whether issuing the letter has varied other employment conditions.

Employee acknowledgement: A signature block for the employee to acknowledge receipt and acceptance of the new salary terms. Under Section 535 of the Fair Work Act 2009 (Cth), employers must maintain pay records and the signed increment letter forms part of those records. Records must be retained for seven years under regulation 3.44 of the Fair Work Regulations 2009. The forms-legal.com Salary Increment Letter (Australia) template includes all these elements and is suitable for use across all Australian states and territories. Disputes about underpayment may be referred to the Fair Work Ombudsman or the Federal Court of Australia.
