What does a work health and safety consultant do and can a consultant bring value to my business are questions we are often asked. This article covers many of the activities that a WHS consultant or an OHS Consultant performs. Ultimately, a work health and safety (WHS) consultant is an independent work health and safety specialist who helps an organisation identify hazards, control risks, and meet its legal duties under Australian WHS or OHS law. The work combines highly specialist advice, audits, risk assessments, incident investigation, training, and the design of safety management systems.
A WHS consultant’s duties typically include:
- assessing the workplace to identify physical and psychosocial hazards
- evaluating workplace risks and recommending controls using the hierarchy of control
- researching complex compliance obligations for businesses
- advising duty holders on their obligations under the relevant WHS or OHS Act
- conducting work health and safety audits and workplace inspections
- investigating incidents and supporting notifiable incident reporting
- managing psychosocial risk alongside physical risk
- arranging occupational hygiene and exposure monitoring where it is needed
- developing safety management systems, procedures, and records, for example to ISO 45001
- delivering training and building safety capability
- supporting consultation and a constructive safety culture
- providing expert advice on complex technical work health and safety issues that a business is facing
The sections below set out what each of these involves, when an organisation should engage a consultant, and how to judge whether a work safety consultant is the right one.
What does a WHS consultant do?
The list above is the shape of the role. In practice the work falls into a few connected areas, and a good consultant moves between them rather than treating each in isolation.
Identifying hazards and assessing risk
Most engagements begin here. The consultant examines how work is actually carried out, not only how a manual says it should be, and identifies the hazards that work creates for employees, contractors, and visitors. Each hazard is then assessed for the likelihood and severity of harm, and controls are recommended in order of effectiveness, with elimination and engineering controls preferred over administrative measures and personal protective equipment. The output is usually a risk register that an organisation can act on and maintain.
Advising on legal duties and compliance
A WHS consultant interprets what the law requires of a particular business and translates it into practical steps. That covers the primary duty of care, the duties of officers and workers, consultation obligations, incident notification, and the codes of practice and Australian Standards relevant to the work. Advice of this kind helps a business avoid enforcement action and, just as importantly, builds the evidence that officers have exercised due diligence.
Auditing and inspecting
Audits and inspections test whether a safety system works in practice. A WHS audit is an independent examination of safety practices against a defined standard, commonly following AS/NZS ISO 19011, and it identifies both compliance and opportunities to improve. Inspections are narrower and more frequent, checking a site or a process against a checklist. Both produce findings and corrective actions, and the value lies in whether those actions are tracked to completion.
Investigating incidents
When something goes wrong, the consultant establishes what happened and why, and identifies the systemic causes rather than stopping at individual error. Good incident investigation separates the immediate trigger from the organisational conditions that allowed it, and it supports the duty to notify the regulator where a death, serious injury, or dangerous incident meets the notification threshold. The findings feed back into the risk controls so the same failure is less likely to recur.
Managing psychosocial risk
Safety is no longer only about physical harm. Since psychosocial hazards became an explicit regulatory focus across the country, including Victoria’s Occupational Health and Safety (Psychological Health) Regulations 2025 from 1 December 2025, every Australian jurisdiction now expects psychological health to be managed with the same rigour as physical safety. A consultant helps a business treat hazards such as high job demands, low support, bullying, harassment, aggression, and exposure to trauma as a technical safety matter. That means a structured psychosocial risk assessment, controls drawn from the design of work, and evidence of monitoring, rather than a policy statement alone.
Occupational hygiene and exposure monitoring
Some hazards cannot be judged by eye. Occupational hygiene is the discipline of measuring and controlling exposure to airborne contaminants, noise, dust, chemicals, and heat. Where a workplace involves substances with a workplace exposure standard, a consultant arranges exposure monitoring by a qualified hygienist, interprets the results against the relevant standard, and recommends controls. This work also produces the defensible records that a regulator or an insurer may later ask to see.
Building systems, training, and culture
The longer-term work is to leave a business better able to manage its own safety. That includes designing or improving a safety management system, often aligned to ISO 45001, writing procedures and safe work method statements, and delivering training that builds genuine competence rather than attendance records. A consultant also supports consultation with workers and health and safety representatives, because a system that people understand and use is more likely to work in practice.
WHS or OHS? The duty holder and the law
Most of Australia operates under harmonised work health and safety laws based on the model WHS Act. New South Wales, Queensland, South Australia, Tasmania, the Australian Capital Territory, the Northern Territory, Western Australia, and the Commonwealth have each enacted their own version, overseen by a state or territory regulator such as SafeWork NSW, Workplace Health and Safety Queensland, or Comcare for Commonwealth workplaces. Victoria sits outside the harmonised scheme and applies the Occupational Health and Safety Act 2004, administered by WorkSafe Victoria, using the language of the employer rather than the person conducting a business or undertaking. The duties are broadly similar in substance.
A consultant working nationally has to apply the provisions that bind each particular duty holder, because the differences between jurisdictions, and Victoria in particular, change what compliance requires. One point is worth stating plainly. The primary duty rests with the person conducting the business or undertaking, or with the employer in Victoria, and it cannot be contracted out. A consultant strengthens how that duty is met and records the diligence behind it, but the legal responsibility stays with the organisation.
When an organisation needs a WHS consultant
Few businesses need a consultant on every matter, and many manage routine safety in-house. External expertise tends to earn its place at particular moments, which commonly include:
- on purchase or acquisition of a new business
- rapid growth, a new site, or a change in the nature of the work
- entry into higher-risk work such as construction, confined spaces, or hazardous chemicals
- a notifiable incident, a regulator visit, or an improvement or prohibition notice
- preparation for ISO 45001 certification or a tender prequalification
- new obligations the business is not yet set up to meet, such as psychosocial risk management
- the absence of in-house safety expertise, or a need for an independent view
For smaller businesses, the practical answer is often ongoing support rather than a one-off project. Fixed-fee arrangements such as small business safety packages provide regular audits, procedures, and access to advice without the cost of a full-time safety manager.
Consultant, safety officer, or health and safety representative
Organisations often confuse a WHS consultant vs safety officer. These roles are easily confused but they are substantially different and not every good safety officer can be a good WHS consultant. A safety officer or WHS manager is usually an employee responsible for day-to-day safety within a single organisation. A health and safety representative is a worker elected by their work group to represent colleagues on safety matters, with specific powers under WHS law. A WHS consultant is an external specialist engaged for independent expertise, a defined project, or capability the business does not hold internally. The three often work together, with the consultant supporting the internal team rather than replacing it.
What to look for in a WHS consultant
No single licence is required to practise as a WHS consultant or OHS Consultant in Australia, so credentials, independence, and relevant experience are the better guide than a job title alone. Useful indicators include:
- a tertiary qualification in work health and safety WHS or a related discipline (or significant experience in practice over many years
- membership of the Australian Institute of Health and Safety, including certified or chartered status, which reflects assessed competence
- for hygiene work, a hygienist certified through the Australian Institute of Occupational Hygienists
- for auditing, recognised lead auditor training and familiarity with AS/NZS ISO 19011
- experience in the relevant industry, so that advice fits the actual hazards and operating conditions
- accreditation of the consultancy itself, such as ISO 9001, 45001, and 14001 certification
The strongest signal is whether a consultant can classify a finding honestly, explain the reasoning, and frame a path forward that a business can act on, rather than offering reassurance that is not supported by the evidence.
How Safetysure approaches WHS consulting
Safetysure is an ISO 9001, 45001, and 14001 accredited work health, safety, and occupational hygiene consultancy operating across Queensland, New South Wales, Victoria, Western Australia, and the ACT. Its consultants work across the full breadth of the role described above, from advice and audits to risk assessment, psychosocial risk management, occupational hygiene, incident investigation, training, and the design of safety management systems.
Two principles run through that work. The first is that a finding is classified on the evidence against the legal requirement, then written constructively, so that the message stays accurate while the path forward stays supportive. The second is that controls should be systemic rather than isolated, because a safety system cannot be understood, or improved, by looking at its parts one at a time. Organisations seeking WHS advice, an audit, psychosocial risk management, or occupational hygiene support can reach Safetysure through its range of WHS consulting services, on 1300 087 888, or at admin@safetysure.com.au.
Frequently asked questions
What does WHS stand for, and how is it different from OHS? WHS means work health and safety, the term used in the harmonised laws adopted by most states, territories, and the Commonwealth. Victoria uses occupational health and safety, or OHS, under its own Act. The duties are broadly similar, and many consultants work under both frameworks.
What qualifications does a WHS consultant need? There is no single mandatory licence, so qualifications and experience are the better guide. Common credentials include tertiary qualifications in work safety, membership of the Australian Institute of Health and Safety, and, for hygiene work, certification through the Australian Institute of Occupational Hygienists. For auditing, familiarity with AS/NZS ISO 19011 is relevant.
When should a business engage a WHS consultant? Common triggers include acquisitions, rapid growth, higher-risk work, a notifiable incident or a regulator visit, preparing for ISO 45001 certification or a tender, new obligations such as psychosocial risk management, or simply the absence of in-house safety expertise. Smaller businesses often choose ongoing support over a one-off engagement.
What is the difference between a WHS consultant and a safety officer? A safety officer is usually an employee managing safety day to day inside one organisation. A WHS consultant is an external specialist engaged for independent expertise, a defined project, or capability the business does not hold internally. The two commonly work together.
Can a WHS consultant make a business compliant? A consultant helps an organisation achieve and demonstrate compliance, but the primary duty under WHS and OHS law rests with the person conducting the business or undertaking, or the employer in Victoria, and cannot be transferred. Good advice lowers risk and records the diligence behind decisions. It does not move the legal duty.
