Australian workplace laws and what your business must do to comply

Every Australian business that employs people answers the same basic question: what does the law actually require of me? The answer rarely sits in one place. Your obligations as an employer come from the Fair Work Act 2009 (Cth), the National Employment Standards it contains, any modern award that covers your industry, work health and safety laws, anti-discrimination law, the Privacy Act 1988 (Cth), and state and territory rules such as workers compensation.

The stakes have risen. Since 1 January 2025, deliberately underpaying an employee is a criminal offence in Australia, not just a civil wrong. A misclassification, a missed award rate or an outdated policy can now cost far more than the dollars involved.

This guide sets out who must comply with Australian workplace laws, the core duties you need to meet from day one, the consequences of getting them wrong, and a practical checklist for staying compliant as you grow.

Who must comply, and the thresholds that apply

Most private sector employers in Australia are national system employers under the Fair Work Act, including companies, sole traders, partnerships and not-for-profits that employ staff. In most states and territories the national system covers almost all private employers. The National Employment Standards in s 61 of the Fair Work Act apply to every national system employee and cannot be displaced by a contract or enterprise agreement.

Three thresholds decide which of your obligations bite:

Headcount: A small business employer employs fewer than 15 employees. This matters most for unfair dismissal. An employee must complete 6 months of service before they can make an unfair dismissal claim, but 12 months if you are a small business employer, and small businesses can rely on the Small Business Fair Dismissal Code.
Turnover: The Privacy Act applies to organisations with annual turnover above $3 million. It also applies to smaller businesses in listed categories, including health service providers that hold health information, businesses that trade in personal information, and contractors to the Commonwealth.
Engagement type: Whether a worker is an employee or an independent contractor decides whether the National Employment Standards and modern awards apply at all. Courts look at the totality of the relationship, not just the label in the contract. Treating an employee as a contractor can expose you to backpay, unpaid superannuation and penalties.

Some duties apply regardless of size. Work health and safety law reaches every person conducting a business or undertaking (a PCBU), even sole traders, and extends to contractors, volunteers and visitors. Anti-discrimination and harassment duties apply to every employer, whatever its turnover.

Pay, awards and the National Employment Standards

The National Employment Standards are the minimum entitlements that apply to every national system employee. Under s 61 of the Fair Work Act they cover maximum weekly hours, requests for flexible working arrangements, parental leave, annual leave, personal/carer's and compassionate leave, community service leave, long service leave, public holidays, notice of termination and redundancy pay, casual employment, and superannuation contributions. Employees must also receive the Fair Work Information Statement when they start.

On top of the Standards sit pay rates. The national minimum wage is $948.00 per week for 38 ordinary hours, or $24.95 per hour, from 1 July 2025 after the 3.5 per cent increase in the 2024-25 Annual Wage Review. That is the floor for award-free adult employees.

Most employers, however, need to look past the minimum wage. If a modern award covers your industry or occupation, its minimum rates apply instead, and it will typically set penalty rates, allowances, overtime and rostering rules on top of the National Employment Standards. Award coverage depends on the nature of the work and the industry, and employees are classified into levels within the award. A pay audit that checks each role against the correct award, classification and current rate is the single most useful compliance exercise for most businesses, and it should be repeated whenever rates change on 1 July.

Superannuation and payroll

You must pay superannuation guarantee for eligible employees, and for contractors engaged under contracts that are wholly or principally for their labour. The super guarantee rate is 12 per cent from 1 July 2025, up from 11.5 per cent. Contributions must go to a complying fund, and eligible employees can generally choose their fund. From 1 July 2026 the new Payday Super rules require you to pay super each payday rather than quarterly, so it is worth building payroll processes now.

Super sits alongside the usual tax obligations of withholding PAYG from wages and reporting through Single Touch Payroll. These are ATO-administered rules, so check the latest guidance and have an accountant or bookkeeper review your setup.

Work health and safety

Every person conducting a business or undertaking has a primary duty under s 19 of the Work Health and Safety Act 2011 (NSW) (and equivalent laws in other states and territories) to ensure, so far as is reasonably practicable, the health and safety of workers and anyone else affected by the work. That duty is not delegable and it reaches beyond employees to contractors, sub-contractors and volunteers.

In practice it means providing and maintaining a safe work environment, safe plant and structures, safe systems of work, adequate facilities, and the information, training and supervision workers need. It also means consulting with workers about health and safety matters.

Physical hazards are only part of the picture. Since 2022, WHS regulations in most Australian jurisdictions, including New South Wales, expressly require businesses to manage psychosocial risks: bullying, excessive workloads, poor job design and low role clarity are now squarely part of the primary duty. Regulators investigate psychosocial complaints seriously, so a safety program that only covers slips, trips and machinery is incomplete.

Anti-discrimination, sexual harassment and the positive duty

You must not discriminate against workers or job applicants on the basis of protected attributes such as age, race, sex, disability, pregnancy or family responsibilities, whether in recruitment, pay, promotion or termination. Federal and state anti-discrimination laws both apply, and the Fair Work Act separately prohibits adverse action against an employee because of a workplace right or a protected attribute.

The biggest recent change is the positive duty in s 47C of the Sex Discrimination Act 1984 (Cth). Employers and PCBUs must take reasonable and proportionate measures to eliminate, as far as possible, sex discrimination, sexual harassment, hostile workplace environments and related victimisation. This is not a complaints-driven obligation: it requires proactive steps such as policies, training, risk assessment and complaint handling. Since 12 December 2023, the Australian Human Rights Commission can investigate compliance with the duty on its own initiative, issue compliance notices and accept enforceable undertakings. The Fair Work Commission can also make stop bullying orders where a worker has been bullied at work.

Privacy and employee information

Employers collect a great deal of personal information: from job applicants, through onboarding, and throughout the employment relationship. Whether the Australian Privacy Principles in the Privacy Act apply to you depends on the $3 million turnover threshold and the listed exceptions discussed above.

If you are an APP entity, there is an important nuance. Under s 7B(3) of the Privacy Act, an employer's handling of employee records is largely exempt where it is directly related to a current or former employment relationship. That exemption does not protect the personal information of job applicants collected during recruitment, and the government has flagged removing the employee records exemption, so treating all workforce information carefully is the safer position.

An APP entity must have a privacy policy, collect information only with notice and consent where required, keep it secure, and comply with the Notifiable Data Breaches scheme when there is a serious breach. Even if the Privacy Act does not cover you, state privacy laws, contractual obligations and the expectations of candidates and staff all argue for the same discipline: collect only what you need, tell people why, and protect it.

Record-keeping and payslips

Employers must make and keep accurate and complete records covering hours worked, wages paid, leave taken and balances, superannuation contributions and termination details. Under the Fair Work Act and Regulations, records must be kept for 7 years, must be legible and readily accessible to a Fair Work Inspector, and must not be false or misleading. Every employee must also receive a pay slip within one working day of being paid, showing the rate of pay, gross and net amounts, deductions, and loadings or penalty rates.

The consequences of getting it wrong

Non-compliance is enforced through several channels, and the penalties have escalated.

Criminal wage theft: Since 1 January 2025, intentionally underpaying an employee is a criminal offence under the Fair Work Act. An individual can face up to 10 years imprisonment and fines, and companies can be fined the greater of three times the underpayment or 25,000 penalty units. The Fair Work Ombudsman investigates and refers matters for prosecution, and a voluntary code protects small businesses that honestly self-correct.
Civil penalties: Underpayments, record-keeping failures and contraventions of the National Employment Standards attract civil penalties, and the Ombudsman routinely litigates wage underpayment cases, including against companies that have since folded.
WHS prosecution: Safety regulators can prosecute businesses for breaches of the primary duty, with substantial fines for corporations and, in the most serious cases of reckless conduct, imprisonment for individuals.
Unfair dismissal: The Fair Work Commission can order reinstatement or compensation where a dismissal was harsh, unjust or unreasonable and the employee had the minimum service period.
Discrimination and harassment: The Australian Human Rights Commission can investigate the positive duty, and courts can award compensation for unlawful discrimination and sexual harassment.
Privacy: The Office of the Australian Information Commissioner can investigate, make determinations and seek civil penalties for serious or repeated privacy breaches.

A compliance checklist for your business

Work through this checklist when you onboard a new worker, review your pay after each 1 July rate change, or prepare for an audit:

Classification: Confirm in writing whether each worker is an employee or contractor, and keep the contract consistent with the real working relationship.
Award coverage: Identify which modern award applies to each role, check the classification, and apply the correct rates, penalties and allowances.
Pay and super: Pay at least the award or national minimum wage rates, pay super at 12 per cent, and update payroll after every 1 July rate change.
Safety: Document risk assessments covering physical and psychosocial hazards, provide training, and consult with workers.
Harassment and discrimination: Maintain policies and training, handle complaints promptly and fairly, and take proactive steps to meet the positive duty.
Privacy: Publish a privacy policy, give collection notices, secure the data you hold, and have a breach response plan.
Records and payslips: Keep records for 7 years and issue pay slips within one working day of payday.
Starting documents: Give every new employee a written employment contract, the Fair Work Information Statement, and the policies that apply to them.

When a workplace lawyer is worth engaging

Much of this is doable in-house, but certain situations justify professional help. Get advice before you classify a borderline worker as a contractor, when you are not sure which award applies, when an employee is dismissed or made redundant, when a regulator contacts you, and when you are restructuring or changing engagement models. A workplace lawyer can map roles to the correct instruments, audit pay against entitlements, draft contracts and policy suites, and, most importantly, advise before a decision is made rather than after a claim is filed.

Start with your classifications and award rates

If you only act on one thing this week, check how each worker is engaged and what they are actually paid. Most underpayment disputes trace back to one of two mistakes: employees treated as contractors, and award rates applied to the wrong classification. Since intentional underpayment became a criminal offence on 1 January 2025, the line between an honest mistake and deliberate underpayment carries real consequences, and the businesses that fare best are the ones that can show they audited, found the problem and fixed it. List every worker, confirm their status and award coverage, and check their pay against the rates that applied from 1 July 2025.
