Union right of entry on residential construction sites in Australia
How union right of entry works on residential construction sites. Fair Work Act Part 3-4 entry notices, WHS entry, permit checks and what builders must and must not do.
What it is
Union officials can enter Australian workplaces, including residential construction sites, only where a statute gives them the right. The two main pathways are Part 3-4 of the Fair Work Act 2009 (Cth) for industrial purposes, and the relevant state or territory work health and safety law for safety purposes. Both pathways require a current entry permit, advance notice in most cases, and compliance with strict rules about where the official can go and what they can do.
Residential builders sit in the middle. They control the site, they hold the duties under WHS law, and they carry the legal risk if they either obstruct a lawful entry or allow an unlawful entry. Getting the process right keeps the site safe, lawful and productive.
Entry permits and identification
Only a permit holder issued by the Fair Work Commission can exercise a Fair Work right of entry. The FWC publishes the Right of entry permit register where builders can verify a permit before allowing entry.
A WHS entry permit is issued under the relevant state or territory WHS Act and must also be held by the official entering for safety purposes. WHS entry permits sit under each jurisdictions WHS Act with rules that mirror the model WHS provisions.
What the builder must check
- The official is a current Fair Work permit holder or current WHS entry permit holder, depending on the purpose
- The entry notice or exemption certificate matches the purpose stated for entry
- The official has produced their permit and photo identification on request under section 489 of the Fair Work Act
A builder who refuses entry to an official who fails to produce a permit is not obstructing entry. A builder who refuses entry to an official with a current permit and a valid notice can be prosecuted for obstruction.
Entry notices and timing
Under section 487 of the Fair Work Act, a permit holder entering to investigate a suspected contravention or to inspect records must give the occupier and any affected employer an entry notice at least 24 hours and not more than 14 days before entry. The notice must state the day of entry, the section of the Act relied on and the suspected contravention or purpose.
For entry to hold discussions with members under section 484, the same 24 hour notice rule applies. The official can only hold discussions during meal or other breaks and only in a place agreed with the occupier or, failing agreement, decided under the Fair Work Regulations.
The FWC can issue an exemption certificate under section 519 allowing entry without 24 hour notice, but only where giving notice would risk evidence being concealed or hinder an underpayment investigation.
For WHS entry, a permit holder must give as much notice as is reasonably practicable, and the model WHS provisions generally allow immediate entry where the official reasonably suspects a contravention that is exposing a worker to a serious risk to health or safety.
What the official can and cannot do
A Fair Work entry permit allows the official to inspect work, interview workers who agree to be interviewed, inspect and copy specified records, and hold discussions in agreed locations. It does not allow the official to direct workers, stop work, photograph the site without consent or interfere with the builders work.
A WHS entry permit allows the official to inquire into the suspected contravention, consult workers and the person conducting the business or undertaking, and warn anyone exposed to a serious risk. Photographing safety hazards is generally allowed where it is reasonably necessary for the WHS purpose.
The official must comply with reasonable site induction and personal protective equipment requirements. A builder cannot use induction or PPE rules to delay or defeat a lawful entry, but can insist on genuine safety steps that apply to any visitor.
Builder duties and risk points
The Fair Work Act creates offences for hindering or obstructing a permit holder (section 502), and for misuse of entry by the permit holder. The model WHS laws likewise create offences for hindering a WHS permit holder. Penalties apply to individuals and corporations and can be significant.
Common residential site risk points:
- Allowing entry without checking the permit or the notice
- Refusing entry where the notice and permit are valid
- Failing to provide reasonable access to records the notice covers
- Letting the official roam the site outside the scope of the notice
- Using induction rules to delay entry beyond what safety reasonably requires
A site manager who is not confident the entry is lawful should escalate to head office, ask the official to wait at the site office and call the builders WHS or IR adviser before refusing or allowing access.
FWC disputes and practical playbook
If a builder believes a permit holder has exceeded their rights, the builder can apply to the Fair Work Commission for orders dealing with the dispute under section 505 of the Fair Work Act. The FWC can suspend or revoke permits where there has been serious misuse. Builders should document the entry, the notice, the conduct on site and any obstruction or misconduct claims on the day so the contemporaneous record is available if a dispute follows.
Train every site supervisor on the two pathways and the permit check. Keep a printed copy of the head contractor entry procedure in the site office. Verify permits against the FWC register before allowing entry. Escort the official to the location specified in the notice, observe but do not interfere with discussions, and log the visit with the time in, time out and purpose. That record protects the builder if a dispute reaches the FWC.
