Employment Contracts Explained: Which Agreement Should You Actually Use?

Issuing the wrong engagement agreement is rarely just a clerical oversight. In Australia, it can expose businesses to underpayment claims, retrospective tax liabilities and Fair Work Commission disputes.

Many business owners default to casual hires or ABN contractors under the assumption that these arrangements provide maximum flexibility and minimal dismissal risk. However, recent changes to the Fair Work Act 2009 have changed the rules governing several employment arrangements. Calling a worker a contractor or a casual in a letter of offer does not determine their legal status if the practical reality of the working relationship tells a different story.

For an overview of employment agreements and the relationship between contracts, awards and minimum entitlements, consult the Fair Work Ombudsman’s employment contracts guidance.

Navigating the various types of employment contracts in Australia requires matching the legal nature of the role with the appropriate employment agreement. Below is a breakdown of how each arrangement operates, when to use it and the commercial risks to consider.

Businesses unsure which employment arrangements are appropriate for their workforce can seek support through Liquid HR’s HR consulting services, which help organisations navigate employment matters and workplace obligations.

1. Permanent Full-Time Contracts

When to Use

Permanent full-time contracts are suitable for core operational, managerial and administrative roles where work is ongoing, predictable and central to daily business operations.

Operational Framework

Standard ordinary hours are generally 38 hours per week, plus reasonable additional hours.
Employees receive applicable National Employment Standards (NES) entitlements, including four weeks of paid annual leave (five weeks for eligible shiftworkers), paid personal/carer’s leave, compassionate leave, paid public holidays and other applicable entitlements.
Eligible employees may access unfair dismissal protections after completing the relevant minimum employment period: six months for most businesses and 12 months for small businesses with fewer than 15 employees.
Terminations must comply with applicable legislation, contractual obligations and any relevant industrial instrument.

Must-Have Clauses

Specific Award Classification: Identify the applicable modern award and classification level where relevant, such as the Clerks—Private Sector Award 2020, Level 3. If the employee is award-free, ensure this position is supported by the applicable coverage rules.
Comprehensive Set-Off Clause: If paying an annual salary instead of an hourly rate, ensure the contract clearly specifies which award entitlements the salary is intended to satisfy. Any set-off arrangement must be legally effective and comply with applicable requirements, including any obligations to record hours and reconcile entitlements.
Intellectual Property and Restraint: Include appropriate provisions addressing intellectual property ownership and, where justified, reasonable post-employment restrictions.

2. Permanent Part-Time Contracts

When to Use

Permanent part-time contracts suit ongoing positions requiring fewer than 38 hours per week with a consistent and predictable work schedule. Examples include specialist finance roles, fractional operations positions and recurring mid-week shifts.

Operational Framework

Employees receive applicable NES entitlements, including annual leave and personal/carer’s leave, calculated according to their ordinary hours of work.
Eligible employees may qualify for redundancy pay and unfair dismissal protections, subject to the relevant statutory requirements.
Working hours and scheduling arrangements should be documented in accordance with the applicable modern award or enterprise agreement.

For a comparison of full-time, part-time, casual and fixed-term employment, see the Fair Work Ombudsman’s guide to types of employees.

The Critical Trap: Modern Award Scheduling

Part-time employment arrangements require careful attention to award-specific requirements. Many modern awards require employers and employees to agree in writing on guaranteed hours and regular work patterns before employment starts.

Depending on the applicable award, the agreement may need to specify working days, start and finish times, and arrangements for varying the agreed schedule.

If a manager regularly asks a part-time employee to work additional hours outside their agreed pattern without following the applicable award requirements, those hours may attract overtime rates rather than ordinary hourly pay.

3. Casual Employment Contracts

When to Use

Casual employment may suit irregular, ad hoc, seasonal or variable work where there is no firm advance commitment to continuing and indefinite work. Examples include covering unplanned absences, managing weekend trading peaks and responding to temporary increases in demand.

The Statutory Test: Section 15A

Under the Fair Work Act 2009, casual employment is assessed by reference to the statutory definition and the practical circumstances of the employment relationship.

Relevant considerations include whether there is a firm advance commitment to continuing and indefinite work, taking into account the real substance, practical reality and true nature of the relationship. The contract’s wording is relevant, but it does not determine the outcome on its own.

Employers should review the Fair Work Ombudsman’s guidance on casual employees to understand the current definition of casual employment, employee entitlements and the process for changing to permanent employment.

Entitlements

Casual loading: Casual employees commonly receive a 25% loading under applicable modern awards or enterprise agreements, although the applicable industrial instrument must be checked.
Leave: Casual employees generally do not receive paid annual leave or paid personal/carer’s leave, but may have access to applicable unpaid leave entitlements.
Other protections: Casual employees may have access to applicable workplace protections, including the Right to Disconnect framework and relevant leave entitlements.

The Employee Choice Pathway

Eligible casual employees may be able to notify their employer that they wish to change to permanent employment under the current employee choice pathway.

Eligibility depends on the employee’s circumstances, including their length of service and whether they meet the statutory criteria. Employers must follow the applicable response process and can only refuse a notification on permitted grounds.

Employers should consult current Fair Work guidance before responding to a request to change from casual to permanent employment.

4. Fixed-Term Contracts

Understanding the difference between permanent and fixed-term contract structures is critical following recent Fair Work reforms.

The Fair Work Ombudsman’s fixed-term contract guidance explains the applicable duration and renewal restrictions, exceptions and Fixed Term Contract Information Statement requirements.

When to Use

Fixed-term contracts may be suitable for roles with a genuine, documented end date, such as:

Backfilling an employee taking 12 months of parental leave.
Specialist work tied to a project with a defined completion milestone, such as a software migration.
Work funded by an external government grant that runs for a specified period.

Statutory Restrictions

The Fair Work Act 2009 places restrictions on certain fixed-term employment contracts, subject to statutory exceptions.

Key restrictions generally include:

Time limit: A fixed-term contract generally cannot exceed two years, including extensions and renewals, unless an exception applies.
Renewal limit: Restrictions generally apply to renewing or extending a contract more than once.
Consecutive contracts: Restrictions apply to certain consecutive fixed-term contracts involving the same employee and substantially similar work.

Employers should review the statutory exceptions and current requirements before issuing or renewing a fixed-term contract.

The Risk

If a fixed-term contract breaches the applicable statutory restrictions, the term specifying when the contract ends may have no effect. Depending on the circumstances, the employee may be treated as ongoing rather than fixed-term.

Employers should not assume that employment can automatically end on the stated expiry date without considering the applicable legal requirements and the circumstances of the employment relationship.

5. Independent Contractor Agreements (ABN)

Engaging someone through an invoice and an Australian Business Number (ABN) does not automatically make them an independent contractor. Distinguishing between an independent contractor and an employee remains an important legal issue for growing businesses.

When to Use

Independent contractor agreements may be suitable when engaging a genuinely independent business to deliver an agreed outcome, supply specialist services or provide professional advice. Examples include engaging an external engineering consultant or an independent software development agency.

The Whole-of-Relationship Test

The legal test for determining whether a worker is an employee or an independent contractor depends on the applicable legislation and the circumstances of the relationship.

For many businesses, the assessment under the Fair Work Act 2009 considers the real substance, practical reality and true nature of the relationship, including its terms and how it operates in practice.

Relevant considerations may include:

Control: Does the business determine the worker’s hours, methods of work and day-to-day activities?
Delegation: Does the worker have a genuine right to delegate or subcontract the work?
Tools and equipment: Does the worker supply their own equipment and incur relevant operating expenses?
Commercial risk: Does the worker bear responsibility for rectifying defects and carry their own business insurance where appropriate?
Independence: Does the worker operate an independent business and have the ability to provide services to other clients?

No single factor necessarily determines the outcome. Businesses should assess the applicable legal test rather than relying on the contract title, ABN status or one characteristic of the arrangement.

Sham Contracting and Superannuation Liabilities

Misclassifying an employee as an independent contractor can expose a business to penalties and claims involving unpaid wages, leave, overtime and other employment entitlements. Other liabilities may arise under workers’ compensation and payroll tax legislation.

Superannuation obligations also require careful consideration. The Australian Taxation Office’s guidance on superannuation for independent contractors explains when contractors may be entitled to Superannuation Guarantee contributions, even when they have an ABN.

6. Individual Flexibility Arrangements (IFAs)

When to Use

An Individual Flexibility Arrangement (IFA) may be appropriate when an applicable modern award or enterprise agreement permits an employer and employee to vary specified terms to better accommodate their individual circumstances.

Depending on the relevant industrial instrument, this may involve arrangements relating to working hours, overtime, penalty rates, allowances or other permitted terms.

The Rules

Better Off Overall Test (BOOT): An IFA must satisfy the applicable requirements, including ensuring that the employee is better off overall under the arrangement than they would be under the relevant award or agreement.
Voluntary: An IFA must be genuinely agreed to and cannot simply be imposed on an employee.
Written Agreement: The arrangement must comply with the applicable formal requirements, including any requirements concerning its content and record-keeping.
Termination: The arrangement may be terminated in accordance with the relevant industrial instrument and statutory requirements. The applicable notice period should be checked before proceeding.

For further information about the Better Off Overall Test, consult the Fair Work Commission’s guidance on how the test operates under the relevant workplace agreement framework.

Contract Selection Matrix

Use the following guide to identify the type of agreement that may suit your workforce requirements.

Need consistent, indefinite work for a role requiring approximately 38 hours per week?
Consider a permanent full-time employment contract that reflects the applicable award classification and remuneration arrangements.
Need reliable, ongoing support for 15 to 25 hours per week?
Consider a permanent part-time contract with agreed hours and scheduling arrangements documented in writing.
Need irregular coverage for demand spikes, events or unplanned leave?
Consider a casual employment contract that complies with the applicable casual employment definition and loading requirements.
Covering a nine-month parental leave absence?
Consider a fixed-term contract, ensuring it complies with applicable restrictions and that the required Fixed Term Contract Information Statement is provided.
Hiring a specialist agency or outcome-based service provider?
Consider a services agreement or independent contractor agreement, after assessing the applicable employee-versus-contractor test.
Need to vary certain award terms for an award-covered employee?
Consider whether an Individual Flexibility Arrangement is permitted under the applicable award and whether all relevant requirements can be satisfied.

Review Your Employment Agreements

Using generic contracts downloaded from the internet or recycling outdated templates can leave businesses exposed to significant legal and financial risks. Every employment agreement should accurately reflect the applicable legal requirements, industrial instrument obligations and operational arrangements.

If your contracts have not been reviewed recently, or you are uncertain whether your ABN contractors are correctly classified under current Fair Work requirements, a thorough contract and classification review can help identify potential compliance gaps.
