Analysis of The Sex Discrimination Act Amendment 2013 – Sexual Orientation, Gender Identity and Intersex Status

Key Amendments Introduced

The 2013 amendment substantially expanded the Sex Discrimination Act 1984. The main changes are:

  1. New Protected Attributes
    • Sexual orientation: attraction to same sex, different sex, or both.
    • Gender identity: a person’s self-perceived gender, regardless of sex at birth or medical intervention.
    • Intersex status: having physical, hormonal, or genetic features that are not wholly male or female.
  2. Repeal of Old Definitions
    • The previous legal definitions of “man” and “woman” were repealed (no replacement definitions were added).
    • This left “woman” and “man” without clear biological/legal meaning in the Act.
  3. Marriage & Relationship Updates
    • “Marital status” was replaced with “marital or relationship status”.
    • Recognised categories now include married, single, divorced, de facto, separated, widowed.
    • New definition of “spouse or de facto partner” also included.
  4. Prohibition of Discrimination Expanded
    • It became unlawful to discriminate on grounds of sexual orientation, gender identity, or intersex status in areas already covered by the Act (employment, education, accommodation, clubs, services, etc.).
  5. Religious Exemptions Modified
    • Religious bodies retained exemptions, but these do not apply in Commonwealth-funded aged care services.
    • This means aged-care providers cannot discriminate against LGBTI people even if religiously affiliated.
  6. Technical Updates
    • “Sexual preference” was replaced with “sexual orientation” across multiple Acts (Fair Work, Broadcasting, Migration).
    • Clarification added that agencies are not required to provide “male/female/other” options in forms and records.

Redefinitions (or Removals)

  • Sex: Not redefined in the 2013 Act. Still a protected ground, but now blurred by added categories.
  • Woman / Man: Both definitions repealed — leaving these categories open to interpretation.
  • Spouse: Extended to include de facto partners and surviving partners.
  • Marital status: Broadened into “marital or relationship status” to cover a wider set of living arrangements.

How This Changed the Original 1984 Act

  • The 1984 Act originally focused on sex discrimination, with sex being tied to male/female biological categories.
  • The 2013 amendments shifted the framework from sex-based protections to identity-based protections.
  • This effectively placed gender identity and intersex status on equal footing with biological sex.
  • It also removed statutory definitions of “man” and “woman,” weakening the clarity of sex-based rights.

Impacts on Women

  1. Loss of Clear Legal Definition
    • With “woman” no longer defined in law, it became harder to argue for sex-specific protections (e.g., single-sex spaces, services, or sports).
  2. Conflict Between Sex and Gender Identity
    • Employers, schools, or service providers must accommodate “gender identity” even when it conflicts with protections for biological women.
    • For example, a male who identifies as a woman may legally claim access to women’s facilities, programs, or opportunities.
  3. Erosion of Sex-Based Exceptions
    • The Act allowed some exceptions (e.g., single-sex clubs, competitive sport, services for one sex only).
    • After 2013, these exceptions were legally weakened since excluding someone based on their gender identity could be unlawful, even in contexts meant to protect women.
  4. Impact on Women’s Advocacy & Services
    • Women’s refuges, legal centres, or health services may be unable to prioritise biological women if doing so could be seen as discrimination against trans-identified males.
    • Religious exemptions don’t apply in aged care, but they do in other contexts—creating inconsistent protections for women.

Comparison of Sex Discrimination Act: Before vs After 2013 Amendments

AreaBefore 2013 (Original Act)After 2013 AmendmentsPractical Effect for Women
Definitions of Sex, Woman, Man“Man” and “woman” were legally defined terms, tied to biological sex.Definitions of “man” and “woman” repealed. No replacement definition given.Removes legal clarity. “Woman” is no longer a fixed category, opening the door for gender identity to override sex in law.
Protected AttributesDiscrimination prohibited on the basis of sex, marital status, pregnancy, family responsibilities.New attributes added: sexual orientation, gender identity, intersex status.Expands protections but dilutes sex-based rights by equating identity with biological sex.
Marital StatusDefined narrowly (married, single, divorced, widowed).Replaced with “marital or relationship status”, recognising de facto and other partnerships.Broader recognition of relationships, minimal direct impact on women, but shifts focus from marriage-only framework.
SpouseMeant husband/wife in marriage.Expanded to include de facto partners and surviving partners.Provides more inclusive coverage, but also erases sex-based language.
Single-Sex Exceptions (clubs, services, sports, refuges, etc.)Allowed where necessary (e.g., competitive sport, women’s refuges, single-sex schools).Still allowed on paper, but restricted by new gender identity protections—excluding someone based on gender identity may be unlawful.Women’s services, sports, and safe spaces face legal risk if they exclude males who identify as women.
Religious ExemptionsReligious bodies could discriminate on sex, marital status, pregnancy in certain contexts.Religious bodies still exempt, but NOT in Commonwealth-funded aged care.Mixed effect: aged care safer for LGBT people, but women’s services run by religious groups can still exclude based on “beliefs.”
Language on SexualityUsed “sexual preference” (outdated term).Replaced with “sexual orientation.”Modernises language, no direct harm to women.
Forms and RecordsSex recorded as male/female.Agencies not required to provide “male/female/other” options, but may.Weakens sex-based data collection, undermining women’s advocacy (e.g., tracking sex-based violence).

Conclusion

  • The 2013 amendments shifted the Act from sex-based to identity-based protections.
  • By repealing the legal definitions of “man” and “woman,” the law blurred who is entitled to sex-specific rights.
  • Women’s services, sports, and advocacy have been weakened because self-declared gender identity can now override biological sex protections.
  • Sex-based data collection (vital for policy, crime stats, and healthcare) has been eroded.
