Disability Discrimination Act 1992

The DDA affects every person and body corporate in Australia that interacts with a person who has, had, may have or is imputed to have a disability. “Disability” is defined expansively in s 4(1) to include physical, sensory, neurological, psychiatric, intellectual and learning disabilities, the presence of disease-causing organisms, and behaviour that is a symptom or manifestation of disability. It expressly covers past, future (including genetic predisposition) and imputed disabilities.

Employers, principals, partnerships, qualifying bodies, registered organisations and employment agencies are directly regulated in the work context (ss 15–21). Educational authorities and providers (including curriculum developers) must not discriminate in admission, expulsion, curricula or benefits (s 22). Owners and occupiers of premises open to the public must provide non-discriminatory access and facilities (s 23). Providers of goods, services and facilities (including professionals, banks, transport operators and government bodies) are covered (s 24). Lessors and agents must not discriminate in accommodation or land dealings (ss 25–26). Clubs, incorporated associations and sporting bodies are regulated (ss 27–28). Anyone exercising a power or performing a function under Commonwealth law or a Commonwealth program is bound (s 29).

Commonwealth agencies and the Crown in right of the Commonwealth and States are bound (s 14), although the Crown cannot be prosecuted. Foreign corporations, trading and financial corporations and their officers are caught to the extent of their constitutional reach (s 12(9)–(10)).

Carers, assistants, interpreters, readers, assistance animals and disability aids receive derivative protection through ss 7–9 and 54A. Associates (spouses, de facto partners, relatives, carers and business or recreational associates) are protected from discrimination based on their association with a person with a disability (s 7).

The Commission, Commissioner and their delegates enjoy immunity for good-faith acts (s 126). Respondents to complaints may claim unjustifiable hardship (ss 11, 21B, 29A) or rely on specific exemptions (ss 45–55). Action planners preparing plans under Part 3 are typically larger employers or service providers seeking to demonstrate compliance.

Ultimately the Act affects the entire Australian community. It imposes positive duties on organisations to make reasonable adjustments and to avoid both direct and indirect discrimination. It also empowers persons with disabilities to assert their rights through the complaint mechanism in the Australian Human Rights Commission Act 1986.

The DDA creates a mixture of negative prohibitions and positive duties. The central duty is not to engage in unlawful discrimination. For employers this means non-discriminatory recruitment, terms, promotion, training and dismissal (s 15). Educational authorities must not refuse admission or expel on the basis of disability (s 22). Service providers must supply goods and services on the same terms and in the same manner (s 24). Premises owners must allow access and use of facilities (s 23).

The positive duty to make reasonable adjustments is embedded in the definitions of discrimination. An adjustment is reasonable unless it would impose unjustifiable hardship (definition in s 4(1)). Failure to make such an adjustment can constitute direct discrimination (s 5(2)) or indirect discrimination (s 6(2)). The assessment of unjustifiable hardship under s 11 is holistic and includes the benefit or detriment to any person (including the community), the effect of the disability, financial circumstances, availability of assistance and any action plan.

Organisations have a duty to avoid victimisation of persons who have made complaints, given evidence or asserted rights (ss 42, 58A). Harassment on the ground of disability is separately prohibited in employment, education and service provision (ss 35, 37, 39).

Rights are conferred on persons with disabilities, their associates, carers and assistance animals. They have the right to complain of unlawful discrimination to the Commission. If conciliation fails, they may commence proceedings in the Federal Court or Federal Circuit and Family Court. They are entitled to reasonable adjustments unless unjustifiable hardship is established. They may request information about assistance animals only in accordance with s 54A(5).

Commonwealth agencies have additional duties under s 29 and must comply with any disability standards. The Minister has power to formulate standards (s 31) after consulting States and allowing for parliamentary disallowance. Once made, standards displace the general Part 2 rules for compliant conduct (s 34).

The Commission has the right to intervene in court proceedings with leave (s 67(1)(l)), to examine legislation for consistency with the DDA’s objects (s 67(1)(i)), and to grant exemptions (s 55). The Commissioner may require actuarial data when the s 46 exemption is relied upon (s 107).

Action plans under Part 3 give organisations a structured way to achieve the Act’s objects. While not mandatory, an action plan lodged with the Commission is a relevant circumstance in any unjustifiable hardship assessment (s 11(1)(e)).

The DDA is primarily a civil regime. Most contraventions of Part 2 are not criminal offences (s 41). Enforcement occurs through the complaint process under Part IIB of the Australian Human Rights Commission Act 1986. The Commission inquires into, and endeavours to conciliate, complaints of unlawful discrimination. If conciliation fails, the complainant may apply to the Federal Court or Federal Circuit and Family Court for an order under s 46PO of that Act. Remedies include damages, injunctions, apologies, reinstatement and corrective action. There is no statutory cap on damages.

Three provisions create criminal offences. Victimisation (s 42) carries 6 months imprisonment. Inciting unlawful acts or assisting their commission (s 43) also carries 6 months imprisonment. Publishing or displaying a discriminatory advertisement or notice (s 44) attracts 10 penalty units. The failure to supply actuarial data when required under s 107 is a strict-liability offence of 10 penalty units (s 107(1B)).

The Criminal Code (except Part 2.5) applies to these offences (s 12A). Corporate criminal responsibility follows the attribution rules in s 123.

The Commission may grant exemptions from Divisions 1 and 2 (s 55). Exemptions are for a maximum of 5 years, may be conditional, and are reviewable by the Administrative Review Tribunal (s 56). Notice must be published in the Gazette with reasons (s 57). Acts done in accordance with an exemption are lawful (s 58).

Disability standards are enforced as if they were provisions of the Act. Contravention is unlawful (s 32) and may found a civil complaint. Compliance with a standard is a complete defence to other Part 2 claims (s 34).

Courts must ensure that the Act does not result in an acquisition of property otherwise than on just terms; compensation is payable and the Federal Court has exclusive jurisdiction (s 131).

The DDA is designed to operate concurrently with State and Territory anti-discrimination legislation (s 13(3)). However, once a disability standard is made, the concurrent operation rule does not apply to Division 2A (s 13(3A)). If a person has pursued a State or Territory complaint about the same act, they cannot then complain under the Australian Human Rights Commission Act 1986 (s 13(4)). Double jeopardy for offences is prevented (s 13(5)).

The Act relies on constitutional powers. Section 12 limits the operation of the limited application provisions to Commonwealth employees, corporations, trade and commerce, external affairs and international obligations (including the Disabilities Convention, ICCPR and ICESCR). This drafting ensures validity while preserving the breadth of the substantive prohibitions.

Interaction with industrial law is addressed in several places. Discrimination in registered organisations is unlawful (s 20). Industrial instruments that set wages by reference to capacity for disability support pension recipients are exempt to that extent (s 47(1)(c)–(d)). The inherent requirements exception in s 21A applies to work, promotion and transfer but not to most other detriments or to registered organisations.

The Privacy Act 1988 is referenced in the definitions of Commonwealth agency and principal executive. Genetic information requests are regulated by s 30; an employer may request genetic data to assess inherent requirements or reasonable adjustments but not for unlawful discriminatory purposes.

The Australian Human Rights Commission Act 1986 provides the procedural machinery for complaints, conciliation and court enforcement. The DDA’s functions of the Commission (s 67) are additional to those in the AHRC Act.

International law is incorporated through s 12(8) and the definition of Disabilities Convention. The objects in s 3 reflect the CRPD. Courts may have regard to the Convention when interpreting the Act.

Other Commonwealth statutes are preserved. Migration legislation (s 52), veterans’ and social security pension provisions (s 51), and certain Civil Aviation safety regulations (note to s 47) prevail. The Fair Work Act 2009 interacts through the definition of fair work instrument in s 47 and the registered organisations provisions.

State laws dealing with disability discrimination can operate concurrently except where they conflict with a disability standard. Occupational health and safety legislation may intersect with the infectious diseases exemption (s 48) and the inherent requirements defence.

Although the consolidated text provided does not specify amendment dates, the structure reveals several layers of reform. The most significant recent changes reflect Australia’s ratification of the Convention on the Rights of Persons with Disabilities (CRPD) in 2008. The Disabilities Convention was inserted into s 4(1) and s 12(8)(ba). The objects and application provisions were updated to give effect to the CRPD. The assistance animal provisions (s 54A) and the expanded definitions in ss 7–9 were added to align with Article 9 (accessibility) and Article 20 (personal mobility) of the CRPD.

The introduction of Division 2A (disability standards) in 1999 (with later refinements) was a deliberate shift from a purely complaints-based model to a proactive regulatory one. Standards for accessible public transport, education, employment and premises have been made under s 31. The rationale was to provide certainty for industry and to lift overall compliance rather than relying on individual complaints.

Amendments to the definition of disability clarified that it includes behavioural symptoms (added after cases such as Purvis v New South Wales (2003) 217 CLR 92) and genetic predispositions. The reasonable adjustment duty was strengthened in response to Waters v Public Transport Corporation (1991) 173 CLR 349 and subsequent jurisprudence.

The unjustifiable hardship factors in s 11 were expanded to include action plans and community benefit or detriment, reflecting experience with large-scale compliance programs.

Criminal Code application (s 12A) was added as part of the general application of the Code to Commonwealth offences. Victimisation was split into civil (s 58A) and criminal (s 42) provisions to give complainants a choice of forum and remedy.

These changes were driven by three policy imperatives: compliance with international obligations, moving from reactive to proactive regulation, and addressing judicial interpretations that had narrowed protection (particularly the “comparator” issue in direct discrimination cases).

The High Court’s decision in Purvis v New South Wales (2003) 217 CLR 92 remains the leading authority on the “because of” test in direct discrimination. The majority held that the comparator must be a person without the disability but otherwise in the same circumstances, including any behaviours that are manifestations of the disability. This significantly narrowed the scope of direct discrimination and led to the 2009 amendments that added the clarification in the definition of disability that it “includes behaviour that is a symptom or manifestation of the disability”.

Waters v Public Transport Corporation (1991) 173 CLR 349 established that a requirement can be indirect discrimination even if it is not imposed on everyone; the focus is on its effect. The case also confirmed that the reasonableness of a requirement is judged objectively having regard to all circumstances.

The inherent requirements defence has generated litigation. In Qantas Airways Ltd v Christie (1998) 193 CLR 280 the High Court held that the “inherent requirements” of a pilot’s position included the ability to fly internationally, so an age limit was lawful. Courts now routinely apply the three-step test from Christie and the factors in s 21A(2).

Unjustifiable hardship has been litigated in education and accommodation cases. Tribunals weigh the cost against the benefit to the individual and the community. The burden is on the respondent (s 11(2)), which has encouraged organisations to produce detailed costings and alternative proposals.

The validity of disability standards has not been directly challenged, but their interaction with the general Act has produced controversy. Some argue that standards create a “deemed compliance” safe harbour that is too generous; others say they provide essential certainty for infrastructure providers.

Victimisation claims have increased. Courts have given the term a broad interpretation, protecting not only formal complainants but anyone who has “reasonably asserted” rights (s 42(2)(f)). The overlap between the civil and criminal provisions has caused procedural complexity.

Controversies also surround assistance animals. Section 54A was inserted after cases in which businesses refused entry to persons with psychiatric assistance dogs. The provision balances the rights of the person with disability against public health and property damage concerns.

The constitutional reach of the Act (s 12) has been assumed rather than litigated, but the incorporation of the CRPD has expanded the external affairs power basis. Any future challenge would likely focus on whether particular standards are supported by the disabilities convention.

Most practitioners miss that the definition of “disability” in s 4(1) is not limited to current impairments. A person who “may” have a disability in the future (including genetic predisposition) or who is imputed to have one is covered. Behaviour that is a symptom or manifestation is expressly included “to avoid doubt”. This catches many workplace disciplinary cases that appear to be about conduct but are in truth about disability.

The “comparator” in direct discrimination is not a person in identical circumstances but a person without the disability in circumstances that are not materially different (s 5(1)). After Purvis, many respondents argue that the comparator shares all the applicant’s characteristics except the disability. The 2009 clarification that disability includes its manifestations was intended to reverse the practical effect of Purvis, yet the point is still litigated.

Reasonable adjustment is not a freestanding duty; it is embedded in the definitions of discrimination. Failure to adjust can be direct discrimination even if the respondent did not intend to discriminate. The unjustifiable hardship defence is available but the burden is on the respondent and the factors in s 11 are non-exhaustive. Tribunals increasingly expect evidence of alternative funding sources and long-term cost-benefit analysis.

Section 30 prohibits requests for information that would be used to discriminate. The exception in s 30(3) requires the respondent to prove that none of the purposes of the request was unlawful discrimination. This reverse onus is often overlooked. Employers asking about genetic conditions or past workers’ compensation claims frequently fall foul of this provision.

The assistance animal provisions in s 54A are more restrictive than many realise. The animal must meet hygiene and behaviour standards appropriate for a public place. A mere “emotional support” animal that has not been trained to those standards is not protected. The discriminator may request evidence (s 54A(5)) and, if none is produced, may lawfully exclude the animal (s 54A(6)). Property damage remains the owner’s liability (s 54A(7)).

Action plans lodged with the Commission are public documents (s 64(2)). Organisations sometimes assume they are confidential. They are also a relevant circumstance in any unjustifiable hardship defence (s 11(1)(e)), so an incomplete or unimplemented plan can be used against the organisation.

The interaction between the DDA and industrial instruments is subtle. An employer cannot rely on an industrial instrument that has no effect (note to s 47(1)). Purporting to comply with a struck-down clause does not engage the exemption. Conversely, the inherent requirements defence does not apply to most detriments once a person is employed (s 21A(4)).

Finally, the limitation period for court proceedings after a terminated Commission complaint is 60 days (Australian Human Rights Commission Act 1986 s 46PO(2)). Many practitioners miss this short window. Extension is possible but not automatic and requires a satisfactory explanation for the delay.

Compliance begins with understanding the organisation’s legal personality and constitutional reach. Trading corporations should assume the Act applies to all their activities. Government bodies must comply when exercising Commonwealth powers.

A risk assessment should map every point of contact with persons who may have a disability: recruitment, customer service, built environment, information systems, employment policies. Each area should be checked against the specific prohibition (ss 15–29) and the definitions of discrimination (ss 5–6).

Develop and implement an action plan under Part 3 even if not required. The plan must address policy development, communication, identification of discriminatory practices, goals, evaluation and responsible officers (s 61). Lodging it with the Commission makes it a relevant circumstance in any hardship defence.

For employment, review all processes. Job descriptions should identify inherent requirements with evidence (s 21A(2)). Recruitment advertising and selection criteria must not indirectly discriminate. Reasonable adjustments during interviews and induction are mandatory unless unjustifiable hardship is established. Performance management must distinguish between conduct that is, and is not, a manifestation of disability.

Service providers must audit premises for physical barriers (s 23) and policies that exclude (s 24). Transport operators should check compliance with any disability standard. If no standard applies, the general duty remains. Staff training on assistance animals is essential; the s 54A(5) evidence request must be used carefully.

Education providers must ensure curricula do not exclude students with disabilities (s 22(2A)). Reasonable adjustments to assessment and teaching methods are required.

Organisations should establish a clear reasonable adjustment policy with a decision-making protocol that considers the s 11 factors. Document all hardship assessments; the burden of proof lies on the organisation.

Information requests must be scrutinised under s 30. Genetic or disability-related questions should be asked only for the purpose of assessing inherent requirements or identifying necessary adjustments, never for exclusionary purposes.

Complaints handling procedures should treat victimisation as a serious breach. Any person who has made a complaint, given evidence or asserted rights must not be subjected to detriment.

Review insurance and superannuation policies to ensure any differential treatment is supported by current actuarial data (s 46). Retain the data; it may be required under s 107.

If a disability standard exists in your sector, map operations against it. Compliance is a complete defence (s 34). If no standard exists, consider advocating for one or adopting industry guidelines published by the Commission (s 67(1)(k)).

Train all staff, especially managers and customer-facing employees. Training should cover the broad definition of disability, the extension to associates and carers, the duty to adjust, and the prohibition on harassment and victimisation.

Maintain records of adjustments made, hardship assessments, and action plan implementation. These will be critical evidence if a complaint is made.

Finally, treat the Commission’s conciliation process seriously. Most complaints resolve at conciliation. Early offers of adjustment or compensation can avoid court proceedings and adverse publicity. If proceedings are commenced, the Federal Court’s power to order systemic remedies means that one complaint can trigger organisation-wide change.
