Recent public debate following the Federal Court’s decision in Giggle v Tickle has prompted a private member’s bill introduced on 25 May 2026 by a National Party MP seeking to amend the Sex Discrimination Act 1984 (Cth) (SDA). The bill seeks to introduce clearer, and in some contexts prioritised, protections based on biological sex—particularly in areas such as single-sex facilities, services and spaces. The Coalition has indicated support for these changes.
While the bill’s prospects remain uncertain, it raises important questions for employers about how potential legislative change may intersect with existing workplace obligations.
A shifting legal landscape
At present, the SDA protects individuals from discrimination on the basis of both sex and gender identity. Employers are therefore required to ensure that workplace policies and practices do not unlawfully discriminate on either ground.
The proposed amendment signals a potential shift towards giving primacy to biological sex in specific contexts. Even if the legislative change is not enacted in its current form, the broader policy debate reflects increasing scrutiny around how competing protected attributes are balanced in practice.
For employers, this highlights the importance of remaining agile and informed as the legal landscape evolves.
Workplace impact: where issues may arise
Although the proposal is focused on areas such as bathrooms, accommodation and certain services, there are clear overlaps with workplace settings. Employers may need to consider how any changes could affect:
- Workplace facilities – including access to bathrooms, change rooms or other sex-specific spaces
- Policies and procedures – particularly diversity, inclusion, anti-discrimination and workplace behaviour policies
- Dress codes and uniform requirements
- Participation in workplace programs or initiatives that may be sex- or gender-specific
In many cases, these issues already require careful navigation. Any legislative amendment may add further complexity rather than providing a simple resolution.
Managing competing rights and obligations
A key challenge for employers is balancing potentially competing rights—particularly where the rights of individuals based on sex and gender identity may intersect.
Employers should be mindful that:
- Anti-discrimination obligations will continue to apply, even if their scope changes
- Work health and safety duties require employers to provide safe working environments for all employees
- Respectful workplace expectations remain critical, regardless of legal developments
Even if reforms prioritise biological sex in certain contexts, this will not eliminate the need for careful, case-by-case assessment and sound judgement.
Practical considerations for employers
In light of this development, employers may wish to proactively consider:
- Policy review: Are existing policies sufficiently clear, current and adaptable to potential legal change?
- Consistency: Are workplace decisions being made consistently and in line with documented policies?
- Training and communication: Are managers equipped to navigate sensitive issues lawfully and appropriately?
- Escalation processes: Are there clear pathways for handling complaints or conflicts involving competing rights?
- Documentation: Are decisions well-reasoned and recorded, given the potential for scrutiny?
Taking a proactive approach can help mitigate risk, regardless of whether legislative reform proceeds.
The continued role of judgement and expertise
Importantly, even with increased legislative clarity, these issues are unlikely to become purely rules-based. Many workplace scenarios will still require nuanced judgment, taking into account legal obligations, organisational context and employee wellbeing.
For employers, this underscores the ongoing importance of seeking legal guidance when navigating complex or sensitive situations.
Looking ahead
The proposed amendment is part of a broader and evolving national conversation about the scope and operation of discrimination law. Whether or not this particular bill is passed, it highlights the potential for change and the need for employers to stay informed.
