Trade unions and employee representation in Australia
Reviewed by Mellow Editorial Team, HR & payroll content team
Trade unions and employee representation in Australia are governed by a well-established legal framework that gives workers the right to organise, bargain collectively and be represented in disputes — and gives employers clear obligations in how they engage with that process.
What trade unions actually do in Australia
A trade union is an organisation registered under federal or state law that represents workers in a particular industry, occupation or workplace. Unions negotiate pay and conditions on behalf of members, assist with workplace disputes and grievances, and participate in enterprise bargaining.
The Fair Work Act 2009 is the primary federal legislation. It gives unions the right to be involved in enterprise agreement negotiations, apply to the Fair Work Commission on members' behalf, and — in specific circumstances — enter workplaces to hold discussions or investigate suspected breaches of workplace laws.
Union membership has declined significantly over recent decades, sitting well below 15% of the workforce. However, union influence remains strong in sectors such as construction, mining, healthcare, manufacturing and the public service, where density is higher and enterprise agreements are common.
Right of entry: what unions can and cannot do on your premises
One of the most practical questions employers have is what happens when a union official wants to come onto site. The Fair Work Act sets out strict rules.
A union official must hold a valid entry permit issued by the Fair Work Commission. They must give 24 hours' notice before entering for the purpose of holding discussions with members or potential members — except where a permit holder reasonably suspects a work health and safety contravention, in which case different rules may apply under state or territory WHS legislation.
Permit holders can inspect records, interview employees and hold discussions, but only in the meal area or another agreed location — not on the production floor or in areas that would disrupt work. Employers can object to certain entry conditions and apply to the Fair Work Commission for orders if they believe a right of entry is being misused.
Understanding these rules in advance means you are not caught off-guard. Keep a record of any entry notices and the details of the permit holder.
Enterprise bargaining and union involvement
Enterprise agreements are collective agreements negotiated between an employer and employees (or their union bargaining representatives) that set out pay and conditions beyond the relevant Modern Award. Unions act as bargaining representatives for any members who appoint them.
An employer cannot refuse to bargain in good faith once a majority support determination has been issued. Good faith bargaining obligations include attending meetings, disclosing relevant information, responding to proposals in a timely way and genuinely considering and responding to counter-proposals. They do not require either party to make concessions.
The Fair Work Commission must approve an enterprise agreement before it takes effect. It will check that employees are better off overall compared with the relevant Modern Award — the "better off overall test" (BOOT). Agreements typically run for up to four years.
Even if your workforce is not unionised, any employee can appoint any person as their bargaining representative, including a union, for the purposes of negotiating an enterprise agreement.
Non-union employee representation
Not all workplaces have union presence, and not all employee representation is union-based. Employees may be represented by:
- A nominated colleague — a fellow employee the worker trusts to speak on their behalf in a grievance or disciplinary process.
- A support person — commonly present in formal meetings, though the Fair Work Act does not grant an automatic right to a support person; it is best practice to allow one.
- A bargaining representative — any person, union or otherwise, appointed during enterprise agreement negotiations.
Having clear internal procedures — a grievance policy, a disciplinary policy, and documented meeting records — reduces the risk of disputes escalating to the Fair Work Commission regardless of whether a union is involved.
Practical obligations for employers
A few things worth having in place:
Know which Modern Award or enterprise agreement applies. This determines the minimum pay and conditions, and whether a union has a recognised role in your industry.
Respond to union correspondence professionally and promptly. Ignoring letters or refusing to engage can be treated as a failure to bargain in good faith if a bargaining order is in place.
Train managers on right of entry rules. A manager who refuses lawful entry or impedes a permit holder can expose the business to penalties.
Keep records. Payroll records, rosters and time-and-attendance data are among the documents a union permit holder may be entitled to inspect. Single Touch Payroll reporting via STP means payroll data is already reported to the ATO at each pay event, but internal records need to be accurate and accessible too.
Seek advice early in a dispute. The Fair Work Commission offers free conciliation for many disputes, and early engagement often resolves matters before they become formal proceedings.
