Casual Conversion Offer Letter (Australia 2026)
Free template letter for offering a casual employee conversion to permanent employment. Cites the Fair Work Act 2009 and lays out the pattern-of-work basis, new terms, and response process.
Since 26 August 2024 (26 August 2025 for small business), the old employer-offer rule is replaced by the Employee Choice pathway: an eligible casual (6+ months, or 12 months for a small business) notifies the employer of their choice to convert. An employer can still offer or agree to convert by mutual agreement — this letter sets out compliant terms either way.
When is someone no longer a casual?
Under s15A of the Fair Work Act, a person is a casual only if there is no firm advance commitment to continuing and indefinite work, judged on the real substance and practical reality of the arrangement. The factors include:
- Whether you can choose to offer work and the employee can choose to accept or reject it
- Whether continuing work of that kind is reasonably likely to be available
- Whether full-time or part-time employees do the same kind of work
- Whether there is a regular pattern of work (one indicator, not decisive on its own)
If a casual gives you written notice that they want to convert, you must consult them and respond in writing within 21 days, and can refuse only on the grounds in s66AAC. Disputes can go to the Fair Work Commission (s66M).
