Federated Learning in AML: A Smarter Way to Fight Financial Crime in Australia
Federated learning is transforming AML by enabling banks to share intelligence without sharing sensitive data.
Introduction
Financial crime is becoming more sophisticated every year. In Australia, criminals exploit the New Payments Platform (NPP), cross-border corridors, and emerging technologies to launder billions of dollars. Banks and fintechs are under immense pressure from AUSTRAC to detect and report suspicious activity in real time.
Yet no single institution has the complete picture. Criminals spread activity across multiple banks and channels, making it difficult to detect patterns when working in isolation. This is where federated learning in AML comes in. It allows institutions to collaborate on intelligence without exposing customer data, creating a collective shield against money laundering.

What is Federated Learning in AML?
Federated learning is an artificial intelligence technique where multiple parties train a shared model without sharing their raw data. Each institution trains the model locally, and only the model updates — not the underlying data — are shared.
In AML, this means:
- Banks contribute insights into suspicious patterns.
- Sensitive customer data remains within each institution.
- A shared model learns from multiple perspectives, strengthening detection.
It is compliance collaboration without compromising privacy.
Why Australia Needs Federated Learning
1. Fragmented Data
Each bank only sees part of the financial ecosystem. Criminals exploit these gaps by spreading transactions across multiple institutions.
2. Rising Compliance Costs
Institutions are spending billions annually on AML compliance. Shared learning reduces duplication of effort.
3. AUSTRAC’s Push for Innovation
AUSTRAC encourages industry collaboration to strengthen financial crime prevention. Federated learning aligns perfectly with this goal.
4. Real-Time Payment Risks
With NPP and PayTo, money moves instantly. Federated learning enables faster identification of emerging fraud typologies.
5. Protecting Privacy
Australia’s data protection regulations make raw data sharing complex. Federated learning solves this by keeping sensitive data local.
How Federated Learning Works in AML
- Local Training
Each institution trains an AI model on its transaction and customer data. - Model Updates Shared
Only the learned patterns (model weights) are sent to a central aggregator. - Global Model Improved
The aggregator combines updates from all banks into a stronger model. - Distribution Back to Banks
The improved model is sent back to each bank for use in detection.
This cycle repeats, continually improving AML detection across the industry.

Use Cases of Federated Learning in AML
- Mule Account Detection
Identifies networks of mule accounts across different banks. - Cross-Border Laundering
Tracks layering activity spread across institutions and jurisdictions. - Fraud Typology Sharing
Allows banks to learn from each other’s fraud cases without sharing customer data. - Sanctions Screening Enhancement
Improves detection of high-risk entities that use aliases or complex networks. - Customer Risk Profiling
Builds more accurate risk scores by learning from industry-wide patterns.
Benefits of Federated Learning in AML
- Collective Intelligence: Stronger models built from multiple perspectives.
- Privacy Protection: Raw customer data never leaves the institution.
- Faster Adaptation: New fraud typologies shared quickly across banks.
- Cost Efficiency: Reduces duplication of AML technology spend.
- Regulatory Alignment: Demonstrates proactive industry collaboration.
Challenges of Federated Learning
- Data Quality: Poor-quality local data reduces model accuracy.
- Technical Complexity: Requires strong IT infrastructure for secure collaboration.
- Coordination Barriers: Banks must align on frameworks and standards.
- Explainability: AI models must remain transparent for AUSTRAC compliance.
- Adoption Costs: Initial investment can be high for smaller institutions.
Case Example: Community-Owned Banks Driving Innovation
Community-owned banks like Regional Australia Bank and Beyond Bank are early adopters of collaborative compliance models. By leveraging advanced platforms, they can access federated intelligence that strengthens their detection capabilities without requiring massive in-house teams.
Their success shows that federated learning is not only for Tier-1 institutions. Smaller banks can benefit just as much from this collaborative approach.

Best Practices for Adopting Federated Learning in AML
- Start with Partnerships: Collaborate with trusted peers to test federated models.
- Focus on Data Quality: Ensure local models are trained on clean, structured data.
- Adopt Explainable AI: Maintain regulator confidence by making outputs transparent.
- Engage Regulators Early: Keep AUSTRAC informed of federated learning initiatives.
- Invest in Infrastructure: Secure, scalable platforms are essential for success.
The Future of Federated Learning in AML
- Industry-Wide Collaboration: More banks will join federated networks to share intelligence.
- Real-Time Typology Sharing: Federated systems will distribute new fraud scenarios instantly.
- Cross-Sector Expansion: Insurers, payment firms, and fintechs will join federated AML networks.
- Global Interoperability: Federated learning models will connect across borders.
- AI-First Investigations: AI copilots will use federated intelligence to guide case investigations.
Conclusion
Federated learning in AML represents a breakthrough in the fight against financial crime. By combining intelligence from multiple banks without exposing customer data, it creates a collective defence that criminals cannot easily evade.
In Australia, where AUSTRAC demands stronger monitoring and fraudsters exploit instant payments, federated learning provides a powerful solution. Community-owned banks like Regional Australia Bank and Beyond Bank demonstrate that collaboration is possible for institutions of all sizes.
Platforms like Tookitaki’s FinCense are making federated learning a reality, turning compliance from a siloed burden into a shared advantage.
Pro tip: The future of AML will be built on collaboration. Federated learning is the foundation that makes industry-wide intelligence sharing possible.
