Occupational Safety and Health Tribunal

The Occupational Safety and Health Tribunal (the OSH Tribunal) assists in the resolution of certain workplace safety and health issues under Western Australia's occupational safety and health laws.

The Tribunal deals with certain issues that may be referred under the following three laws:

The Mines Safety and Regulation Act applies to work that is carried out on a mine, the Petroleum (Submerged Lands) Act applies to work that is carried out on offshore petroleum operations as defined in section 4 of that Act, and the Occupational Safety and Health Act 1984 applies to all other workplaces in Western Australia.

Referring claims to the OSH Tribunal

The claims that may be referred to the Tribunal vary between the three laws. They do have similarities in that all of the matters that may be referred to the Tribunal relate to occupational health and safety at Western Australian workplaces. For more information check the tables in Step 1 -Determining Eligibility.

Please note that claims that may be referred to the Tribunal are not 'industrial matters' as described in section 7 of the Industrial Relations Act 1979 (WA).

Responsibilities of the Tribunal

The Tribunal is required to:

  • proceed as quickly as possible;
  • consider matters according to equity, good conscience and the substantial merits of the case without regard to technicalities or legal form;
  • have regard to the interests of the persons immediately concerned, whether directly affected or not; and
  • have regard, where appropriate, for the interests of the community as a whole.

Determining eligibility

The Tribunal deals with certain issues that may be referred under the following Acts:

A range of people from WA workplaces may refer issues to the Tribunal under specific sections of the laws applying to the Tribunal. Generally, only persons directly affected by a matter arising under the Acts can refer a matter to the Tribunal. This includes:

  • employers;
  • employees;
  • workplace health and safety representatives;
  • contractors;
  • sub-contractors;
  • member(s) of workplace health and safety committees;
  • a member of a designated work group;
  • the Mine Manager; and
  • the State Mining Engineer.

Additionally, the WorkSafe Western Australia Commissioner has standing in relation to many matters and has the exclusive right to refer a matter in some circumstances.

It is recommended that you try to discover under which section of the relevant act you may refer your matter to the Tribunal. The tables below can assist you in understanding the types of matters and the type of persons who can refer a matter to the Tribunal:

Submitting an application

Critical information
What happens after I lodge Form 6?

After you have submitted your Form 6, the Commission’s Registry will:

  • check it to make sure that it contains all the required information;
  • if the form is complete, send a copy of it to you for your records; 
  • if the Tribunal directs so, to serve the parties with the copies of the form. You will then be contacted by the Tribunal to arrange to have your referral dealt with.

Conciliation Conferences

A conciliation conference may be conducted by the Tribunal who can help the parties to resolve their employment dispute. The purpose of the conciliation is to explore whether an agreement can be reached between the parties, not to decide who is right or wrong.

The option of conciliation is available in many (but not all) claims referred to the Tribunal. For instance, see section 51J(1) of the Occupational Safety and Health Act 1984 (WA). Depending on which legislation your application is made under, your application may proceed straight to a formal hearing, where the issue is determined by the Tribunal.

Conciliation conferences are private and are conducted on a 'without prejudice' basis. This means that what is discussed at a conciliation conference cannot be used against one of the parties if the matter goes to hearing. This allows the parties to explore possible settlement options without fear of the other side using any offers or concessions made at the conference as an admission to various aspects of a claim. The conference is not recorded, and no transcript is produced. Any visual or audio recording is strictly prohibited. An agreement may be reached during or after the conference, the parties have control over the outcome before the matter reaches the hearing stage. In contrast, if the matter goes to hearing, the Commission will decide the outcome of the matter.

For more information please read the Commission’s conciliation conference fact sheet by clicking here.

Possible outcomes of conciliation

  • An agreement may be reached during or after the conference.
  • If an agreement is not reached, The Commission may hold further conferences depending on the circumstances, or list the matter for hearing.

What is a hearing?

A hearing is where the Tribunal hears and determines the substance of the issues in dispute. Hearings are more formal than conciliation conferences. In addition, the process may involve a visit by the Tribunal to the workplace.


Interlocutory or preliminary hearings

There may be issues that have to be determined by the Commission before the merits or substance of an application can be dealt with. These preliminary (or interlocutory) matters may relate to an issue with the employee’s claim that needs to be resolved before the rest of the matter can proceed, such as an application for discovery of documents.

Some examples of preliminary issues include:

  • whether the Commission has jurisdiction to deal with the application;
  • whether the employee is under the salary cap; or
  • whether the Commission can accept an application that was made out of time.

There may be one or more interlocutory hearings before the substantive hearing to deal with preliminary or procedural issues.

 A Directions hearing is similar to a preliminary hearing, it is where the Commission will set out how the matter will progress. This can include setting out a timeline for when things ought to occur such as discovery, or when things are to be filed with the Commission, such as outlines of submissions or witness statements.

Substantive hearing

A substantive hearing is where the Commission hears and determines the substance or merits of the employment or industrial issues in dispute.

For information on representation and representing yourself, please read the Commission’s representation fact sheet by clicking here.


Possible outcomes

The outcomes available at hearing will depend on the claim referred. For example, under certain matters compensation may be ordered by the Tribunal.

Application to review decision to affirm improvement notice dismissed as out of time

The Occupational Health and Safety Tribunal (Tribunal) has dismissed an application to review the WorkSafe Commissioner’s decision to affirm an improvement notice issued to a company on the basis that the application was made out of time and that it does not have the power to grant an extension.

A WorkSafe Inspector had issued an improvement notice on 20 July 2020 to a company. A request to the WorkSafe Commissioner to review the improvement notice was submitted on 21 August 2020, and on 20 October 2020, the company received notification that the WorkSafe Commissioner had affirmed the notice.

The company then sought a review of the WorkSafe Commissioner’s decision to affirm the improvement notice. It submitted to the Tribunal that it had sought information from an officer of the Department of Mines, Industry Regulation and Safety concerning the process for further review of the decision, but the information was provided outside of the timeframe specified in the Occupational Safety and Health Act 1984 (OSH Act). The company filed its referral with the Tribunal the following day.

The WorkSafe Commissioner advised the Tribunal that it would be seeking an order to dismiss the matter as the company had not referred the matter to the Tribunal within the specified time limit.

The Tribunal noted that the company’s submissions concerned the reasons for the delay. The Tribunal found, however, that it does not have the power to extend the time limit and thus did not have the discretion to consider the reasons for the delay to extend the time limit.

The Tribunal dismissed the application.

Tribunal referral dismissed due to lack of jurisdiction

Tuesday, 26 March 2019

The Occupational Safety and Health Tribunal (the Tribunal) has dismissed an application for payment of an unspecified amount for continued pay and benefits entitlements and a loss of earnings arising from alleged discrimination against a safety and health representative in relation to employment.

The Tribunal was comprised of Commissioner Walkington who considered the entitlements claim and noted that there is a mandatory process in place for resolving health and safety issues in the workplace, which include circumstances where a worker may cease work without loss of wages and entitlements. The Tribunal further considered that it is necessary for any employee wishing to make a claim to demonstrate that they have refused to work on particular tasks, have notified the employer of their belief of the risk to their safety and health and have made themselves available for alternate duties if it is safe to do so. The Tribunal found that the applicant’s actions were not consistent with the provisions of the legislation and regulations.

The Tribunal then considered that persons who are safety and health representatives or are performing or have performed any function as a safety and health representative can make a claim for discrimination against a safety and health representative in relation to employment. The Tribunal found that the applicant was not eligible to bring this application because the applicant had not demonstrated that he was a validly elected safety and health representative.

The Tribunal dismissed the referral for lack of jurisdiction.

Number of Safety and Health Representatives depends on circumstances of workplace

Thursday, 11 October 2018

The Occupational Safety and Health Tribunal has decided on the number of Safety and Health Representatives (SHRs) and the manner of electing such representatives for a bus depot that services primarily CAT buses.

Senior Commissioner Kenner found that there is no standard formula to determine the appropriate number of SHRs for a workplace and it will instead depend on the circumstances of that workplace. In making such a determination it is necessary to look at the number of employees, working arrangements and hazards, the need for communication between SHRs and employees, the need for SHRs to be available to communicate with the employer on health and safety issues and for the SHRs to be visible and available to respond promptly to incidents and accidents.

The Senior Commissioner noted that the 'workplace', as defined in the Occupational Health and Safety Act, in this circumstance includes the depot and the buses – even when in transit. Evidence was given on the nature of health and safety hazards faced by CAT bus drivers and the limitations to communication during a shift with other employees and the control centre. The Senior Commissioner accepted that the level of hazards in relation to CBD driving was high and that CAT bus drivers face additional hazards in the city environment.

The Senior Commissioner determined that there will be 2 SHRs for each shift, 4 in total, and that a 'first past the post' method of voting following the Electoral Commission's preferred system of voting for only one candidate. The Transport Workers Union and the respondent will jointly conduct elections for any casual vacancies.

Frequently asked questions

Yes. The applicants may request the Tribunal to consider using the provisions of s 27(1)(j) of the Industrial Relations Act 1979 to join multiple applications relating to the same claim.

This will depend on the section of the particular law concerned. As an example where more than one health and safety representatives at a workplace are seeking additional entitlements for attending accredited training courses, then under s 35(3) of the Occupational Safety and Health Act 1984, the health and safety representatives jointly, or their agent, may lodge an application, listing the health and safety representatives’ details as applicants.

Employer organisations and/or unions may refer a claim by acting as the agent of the applicant, pursuant to the provisions outlined in s 31(1)(b) of the Industrial Relations Act 1979. Where the organisation (employer organisation or union) is acting as an agent, applications may be signed by the agent on the applicant’s behalf. Warrant(s) signed by the applicant(s) will need to be filed using Form 11 – Notification of Representative Commencing or Ceasing to Act. For more information about unions and registered organisations check their page here.

The issue of whether a union and/or employer organisation or representative can be identified as a party under s 74(2) of the Mines Safety Inspection Act 1994 has been considered by the Full Bench in: Thiess Pty Ltd and Others v The Automotive, Food, Metals, Engineering, Printing & Kindred Union of Workers – Western Australian Branch & Others (2006).

The forms to be used in proceedings before the Tribunal can be found in our Applications and forms page.

The Tribunal is located at the Western Australian Industrial Relations Commission, Level 17, 111 St Georges Terrace, Perth, WA 6000. For more information see the Contact us page. 

The Tribunal may also hear matters, subject to the availability of the parties, in country towns and regional locations.

The Commission is committed to ensuring its information, facilities and services are accessible to all members of the Western Australian community. For more information on accessibility, please visit our Access and inclusion page.
