When you hear the term ‘Animal Ethics Committee’ (AEC), what comes to mind?
For many people, it sounds reassuring; a group of professionals sitting around a table discussing ethics, weighing up animal welfare, questioning harm, and ensuring animals are treated with dignity and care. It evokes the image of rigorous ethical debate and strong protections for animals used in research. Unfortunately, though, what actually happens inside an AEC is far from this.
How AEC's are supposed to work
AECs are institutional bodies established by universities, hospitals and research organisations to review and approve research involving animals. In Australia, any research involving animals must comply with the Australian Code for the Care and Use of Animals for Scientific Purposes (the Code), which is overseen by the National Health and Medical Research Council (NHMRC).
AECs are made up of four categories of members:
- Category A: Veterinarians with expertise in animal welfare
- Category B: Researchers or scientists actively involved in research
- Category C: Animal welfare representatives
- Category D: Independent laypeople not connected to the institution
On paper, this structure appears balanced. The intention is for different perspectives to come together and carefully assess whether research involving animals is ethically justified. But our Evaluating Animal Research Oversight in Australia report paints a more complicated picture. Through interviews with former and current AEC members, our report identified recurring concerns around conflicts of interest, power imbalances, inconsistent training, limited transparency, and a system that often prioritises refining animal use rather than questioning whether animals should be used at all.
One of the most significant issues raised is that discussions are often dominated by scientific and technical language. Research proposals can involve highly specialised medical terminology, complex methodologies and statistical frameworks that may be difficult for non-scientific members to confidently challenge. As a result, Category C and D members (the very people intended to represent broader ethical and community perspectives) can struggle to participate meaningfully in discussions.
The result is a system where ethical review can become procedural rather than genuinely critical.
As our report states:
“AECs operate within a system that assumes animal use as the default, reducing ethical review to minor refinements in animal care rather than questioning whether animal use is necessary or meaningfully exploring NAMs.”
Problems with the current system
The Code is built around the principle of the 3Rs:
- Replace – use non-animal alternatives wherever possible
- Reduce – minimise the number of animals used
- Refine – minimise pain and distress
While all three principles are important, our report argues that in practice, Replacement is often treated as secondary to refinement and reduction.
This matters because globally, science is changing rapidly. Countries around the world are increasingly investing in human-relevant, non-animal methodologies (NAMs), including organ-on-chip technologies, advanced computational modelling, AI-driven systems, and human cell-based research. Yet Australia’s Code has remained largely unchanged since 2013, aside from a limited amendment banning cosmetic testing. As scientific innovation rapidly progresses, ethical oversight frameworks must also evolve to meaningfully recognise, support, and prioritise emerging non-animal methodologies.
Our report identifies several key weaknesses in the current system:
- Outdated regulations
- Regulatory fragmentation across states and territories
- Limited transparency and public reporting
- Structural and operational barriers within AECs
- Inconsistent training and induction processes
Perhaps most importantly, the current system often asks:
“how can we minimise harm?” rather than, “Is animal use justified in the first place?”
That distinction changes everything…
Our recommendations
AECs have the potential to be meaningful ethical bodies – but only if they are supported by stronger regulations, greater independence, better training, and a framework that genuinely prioritises Replacement.
The current review of the Code provides an opportunity to advance our recommendations, which are aimed at strengthening ethical oversight.
Make Replacement a Priority ...not an afterthought
One of our key recommendations is revising the Code so that animal use becomes a genuine last resort.
This would require researchers to:
- actively demonstrate why non-animal methods cannot be used,
- document what alternatives were explored,
- justify why animal use remains necessary,
- and show that expected benefits outweigh harms.
Currently, many applications focus primarily on minimising harm within animal experiments, rather than rigorously challenging whether the experiment should proceed at all. A stronger Replacement framework would shift the culture of ethical review from passive approval toward active ethical scrutiny.
Strengthen Transparency
Most Australians have little visibility into what happens inside AECs.Our report recommends mandatory participation in the Openness Agreement on Animal Research and the creation of a publicly accessible national database outlining:
- species used
- procedures performed
- predicted harms
- research outcomes
- and whether alternatives were considered.
Transparency matters because public trust cannot exist without public visibility. If institutions are confident their research is ethically justified, that justification should be open to scrutiny.
Improve Training and Support for Committee Members
AEC members are expected to make decisions involving highly technical research proposals, yet induction and training processes are often inconsistent or minimal. Non-scientific members in particular may feel underprepared when reviewing complex biomedical proposals.
We recommend:
- a nationally consistent training framework for all AEC members,
- greater education around non-animal methods and emerging technologies,
- training on ethics, conflicts of interest, and institutional bias,
- and improved support for Category C and D members to participate confidently in discussions.
Ethical review cannot function effectively if some members feel unable to fully participate.
Address Power Imbalances and Conflicts of Interest
Our report also highlights concerns around institutional pressure and committee dynamics. Some members described environments where questioning research could feel uncomfortable or discouraged.
Because AECs are established within the same institutions conducting the research, there can be inherent conflicts of interest. Universities and research institutions may benefit from research approvals through funding, publications, and reputation, making independent and impartial oversight especially important.
We recommend:
- appointing independent chairs to help reduce conflicts of interest and ensure discussions are led impartial
- documenting dissenting opinions to improve transparency and accountability in decision-making
- improving grievance pathways so committee members feel safe raising ethical concerns
- and increasing external oversight through audits and independent review processes to strengthen consistency and public trust.
Ethics committees cannot operate effectively if members feel unable to challenge proposals openly.
Why reform matters
No one is under the illusion that Australia will transition away from animal research overnight…as much as we would like that to be the case! But reform matters because the structure of ethical review shapes the questions we ask. If discussions continue to focus primarily on refining animal experiments, animal use will remain the default. But if committees are empowered to critically examine necessity, challenge assumptions, and actively prioritise replacement methods, the culture of research itself can begin to shift.
AEC reform is not just about improving committee procedure. It is about redefining what ethical scientific progress should look like in Australia.
And perhaps most importantly, it is about ensuring that ethics is not treated as a checkbox but as the centre of the conversation.
