What Medical Information Can an Employer Ask For?

An Australian employer can ask for medical information that is reasonably connected to a legitimate workplace purpose, such as verifying sick leave, understanding current capacity, managing a safety risk or considering reasonable adjustments. The appropriate scope depends on the purpose and circumstances.

Evidence for a short sick-leave absence may only need to confirm that the employee was unfit and state the relevant dates. A return-to-work assessment for a safety-sensitive role may need functional restrictions, expected duration and review information.

That does not mean an employer automatically needs a diagnosis, full medical history, test results or unrestricted access to the employee's treating practitioner. A request should be focused on the workplace decision that must be made.

This article deals with the content an employer may ask for. For the threshold question about requiring evidence, read Can an Employer Ask for a Medical Certificate in Australia?.

This is general information, not legal or privacy advice. Rules differ for public and private employers, prospective employees, workers compensation, regulated roles and state or territory health records. Obtain advice about a disputed or intrusive request.

Key Points

• An employer can ask for reasonable evidence supporting sick or carer's leave.
• A medical certificate generally does not need to state a detailed diagnosis to verify ordinary absence.
• Fitness assessments may require functional capacity, restrictions, likely duration and review timing.
• Health and safety questions should relate to inherent duties and actual workplace risks.
• A request for complete records is much broader than a request for a focused capacity report.
• A treating practitioner ordinarily needs patient consent before discussing health information with the employer, unless another lawful basis applies.
• The Privacy Act's employee-records exemption can limit privacy coverage for some private-sector employment records.
• Employees should ask what decision the information will support and who will receive it.

Medical Certificates

Start With the Purpose of the Request

The same medical question is not reasonable in every context. The employer should be able to explain whether it needs evidence for leave, confirmation of current fitness, information for a workplace adjustment, compliance with a licence or management of a specific safety concern.

Once the purpose is clear, the request can be narrowed. For leave, the key facts may be incapacity and dates. For modified duties, the key facts may be lifting tolerance, hours, breaks and a review date.

A broad request such as “provide your whole medical file” may capture years of unrelated and sensitive information. The employer should consider whether a focused practitioner report can answer the actual question.

Employees can ask for the request in writing, including the reason, questions, deadline, recipient and how the information will be stored.

Information for Sick or Carer's Leave

An employer can ask for evidence showing that an employee was unable to work because of personal illness or injury, or needed to provide eligible care or support. Evidence can be requested for one day or less.

The Fair Work Ombudsman says medical certificates and statutory declarations are examples, and the evidence must satisfy a reasonable person that the employee was genuinely entitled to leave.

For ordinary sick leave, that purpose can often be met by the employee's name, assessment date, period of incapacity, practitioner's details and a statement that the person was unfit for work.

Award or enterprise agreement terms may specify evidence. The employer should not assume that a diagnosis is essential merely because it prefers one.

Does the Employer Need Your Diagnosis?

Often, no. A diagnosis can be highly sensitive and may not add anything necessary to decide whether an employee was away from work for a qualifying health reason.

There are situations where information about the condition may be relevant, particularly when understanding a safety risk, infection control need, prognosis, adjustment or ability to perform inherent duties. Even then, functional information may answer the question without a detailed label.

For example, “no driving or operating mobile plant while taking this medicine” is more useful to a transport employer than a complete account of the condition for which the medicine was prescribed.

Employees can ask the practitioner to focus on capacity and restrictions. Read Medical Certificates and Patient Privacy for a certificate-specific explanation.

Fitness for Work Information

When an employer has a genuine concern about current capacity, it may seek more information than the dates on an absence certificate. The report can address whether the employee can perform identified duties safely.

Relevant questions may cover functional limits, work hours, equipment, driving, manual handling, exposure, shift work, emergency duties, duration of restrictions and the date of review.

The employer should provide a position description or list of inherent requirements. A practitioner cannot assess “full duties” accurately when they do not know what those duties involve.

Safety and Inherent Requirements

An employer may ask focused questions about whether a health condition affects safe performance of essential job tasks. The concern should be grounded in the role rather than stereotypes about a diagnosis or disability.

The Australian Human Rights Commission explains that employers can ask how disability relates to doing the job safely and what workplace changes may assist.

The same guidance notes that, in most circumstances, a worker does not have to disclose a disability that does not affect their work. Where an adjustment is needed, information about the required adjustment may be more relevant than the diagnostic history.

Safety-critical and licensed roles can have specific disclosure and assessment rules. General privacy guidance should not be used to ignore a statutory requirement.

Reasonable Adjustments

An employee may choose to disclose enough information to request a workplace adjustment. Useful information describes the barrier and the change that may support safe, effective work.

Examples include ergonomic equipment, a temporary lifting limit, altered start time, additional breaks, a quiet workspace, accessible technology or a staged return.

The employer may need clarification about how long the adjustment is expected, whether it should be reviewed and whether the employee can still perform inherent requirements.

A practitioner should not promise that a particular adjustment is operationally available. They can describe health-related function; the employer then assesses reasonable implementation under the relevant law.

Can the Employer Contact Your Doctor?

An employer can ask for permission to contact a treating practitioner or send written questions. The practitioner will ordinarily need the patient's consent before disclosing health information, unless disclosure is otherwise required or permitted by law.

Consent should be informed and specific. It can identify the practitioner, recipient, questions, information covered and period for which permission applies.

An employee may prefer to take focused written questions to the appointment and return the practitioner's report. This can reduce misunderstandings and create a clear record.

Do not sign a blank or open-ended authority without understanding it. Read Can My Employer Call My Doctor in Australia? for a detailed discussion.

Can the Employer Ask for Your Full Medical Record?

An entire record can contain unrelated mental health, reproductive health, family history, previous injuries, prescriptions and third-party information. It is a much broader disclosure than a certificate or capacity report.

Ask why the full file is necessary and whether a targeted report, independent examination or selected relevant records would answer the question. The proportionality of the request is important.

Workers compensation, insurance, litigation and regulated health assessment processes may lawfully require more material than an ordinary leave request. Those schemes should identify the authority, scope and safeguards.

Obtain legal, union or privacy advice before refusing a formal request or providing a large clinical file. Both over-disclosure and non-compliance can have consequences.

How the Privacy Act Applies to Employee Records

Health information is generally sensitive information, but workplace privacy coverage has important exceptions. It is unsafe to assume the Australian Privacy Principles apply to every record held by every employer.

The OAIC employee records guidance explains that a private-sector employer's handling of an employee record can be exempt where the act is directly related to the current or former employment relationship.

The exemption does not necessarily cover prospective employees, unrelated uses or contractors handling another employer's records. Australian Government employees and some state public-sector employees operate under different frameworks.

State and territory health privacy laws, confidentiality duties, workplace laws and discrimination law may also apply. The OAIC employment privacy page provides a starting point for identifying the relevant regime.

Pre-Employment Medical Questions

A prospective employer may ask health questions connected to safely performing the inherent requirements of a role. Questions unrelated to the job can create discrimination and privacy concerns.

An applicant should answer lawful, relevant questions honestly. They can ask why information is needed, how it relates to the duties and who will see it.

Pre-employment collection is not covered by the employee-records exemption when an employment relationship does not result. The OAIC collection guidance explains that organisations generally collect information that is reasonably necessary and usually need consent for sensitive information.

Special rules can apply to police checks, safety licences, vaccinations, workers compensation history and particular industries. Tailored advice may be needed.

Independent Medical Examinations

An employer with a genuine capacity concern may sometimes direct an employee to attend an independent medical examination. Whether the direction is lawful and reasonable depends on the circumstances.

The examiner may receive the position description, existing reports and focused questions. The employee should ask what material will be sent and what report the employer will receive.

A Fair Work Commission decision discussing medical examination authorities notes that genuine need and reasonableness are central considerations.

Seek advice before refusing. A dispute about scope can sometimes be resolved by narrowing questions, agreeing on a practitioner or using the workplace dispute-resolution process.

How to Respond to a Medical Information Request

• Ask for the request and its purpose in writing.
• Identify the decision the employer needs to make.
• Check the award, agreement, contract, policy and any scheme rules.
• Ask whether a certificate or focused capacity report is sufficient.
• Obtain the exact job duties and medical questions.
• Read any consent authority before signing.
• Ask who will receive, store and access the report.
• Keep copies of the request, consent and information provided.
• Seek union, legal or privacy advice if the scope appears excessive.

Using Dociva

Dociva accepts online requests for sick-leave, carer's-leave, study and multi-day medical certificates, as well as standard and extended consultations for broader clinical needs. A bespoke employer capacity report requires sufficient clinical and workplace information.

For broader capacity questions, use an available treating or occupational practitioner and provide the employer's written request, relevant dates, actual duties and current symptoms. The practitioner should include only clinically supportable, necessary information.

A certificate is not guaranteed, Dociva does not provide backdated medical certificates, and an online document may not meet every independent, regulated or workers compensation assessment requirement.

Use the medical certificate application when that product matches the evidence needed, or choose the online consultation page for broader assessment. See also What Information Doctors Need During Telehealth Consultations.
