Australia’s proposed Tranche 2 anti-money laundering and counter-terrorism financing (AML/CTF) reforms aim to bring digital currency exchanges (DCEs) and other cryptocurrency service providers into tighter regulatory alignment with traditional financial institutions. While some digital currency operators have been subject to AUSTRAC’s oversight since 2018, Tranche 2 signals a significant shift: more detailed requirements, broader coverage, and stricter enforcement.

As Australia seeks to close compliance gaps and align with international FATF (Financial Action Task Force) standards, digital currency operators — from exchanges to DeFi platforms and crypto custodians — face a range of operational, technical, and regulatory challenges.

1. Broader Scope and Ambiguity of Coverage

One of the key challenges is the uncertainty around how widely Tranche 2 will apply across the digital asset ecosystem. While existing AML/CTF regulations already apply to DCEs providing fiat-to-crypto services, Tranche 2 may:

1. Extend to crypto-to-crypto transactions
2. Include digital wallet providers and crypto ATMs
3. Capture DeFi platforms, NFT marketplaces, and DAO-operated services

The ambiguity around what constitutes a “designated service” under the updated legislation creates confusion for operators — particularly startups and decentralised platforms — who may not yet consider themselves regulated entities. Without clear guidance, operators risk falling into non-compliance inadvertently.

2. Enhanced Customer Due Diligence (CDD)

Under Tranche 2, DCEs will likely be required to go beyond basic identity verification. Operators may be expected to:

1. Conduct risk-based customer profiling
2. Apply enhanced due diligence (EDD) for high-risk transactions or jurisdictions
3. Verify the beneficial ownership of business accounts or institutional clients

This becomes technically and practically difficult in a decentralised ecosystem. Peer-to-peer transactions, anonymity features, and cross-border flows complicate efforts to implement traditional KYC standards.

Additionally, complying with these rules without alienating privacy-focused users poses a commercial challenge.

3. Transaction Monitoring and Blockchain Complexity

Cryptocurrency’s transparency — the open nature of blockchain — is often misunderstood as full traceability. In practice, effective transaction monitoring is highly complex and requires sophisticated tools that can:

1. Track wallet activity across multiple blockchains
2. Flag suspicious behaviours (e.g., structuring, mixing services, rapid fund movement)
3. Detect ties to known illicit entities or high-risk jurisdictions

For many operators, especially startups, acquiring or developing these tools represents a steep financial and technical hurdle. Moreover, transactions can be obscured through privacy coins (like Monero or Zcash), mixers, or cross-chain swaps, increasing the difficulty of identifying real-world risk.

4. Data Privacy and User Resistance

Many cryptocurrency users are drawn to the space for its emphasis on privacy and decentralisation. Mandatory KYC and AML requirements under Tranche 2 may be perceived as antithetical to crypto's core ethos, leading to:

1. User resistance or churn
2. Migration to unregulated offshore platforms
3. Concerns over personal data security, particularly in light of recent data breaches across Australian industries

Operators must strike a difficult balance between regulatory compliance and maintaining user trust. Robust data protection and transparent privacy policies will be essential — but they also add to operational complexity and cost.

5. Cross-Border Risks and Jurisdictional Conflicts

The global nature of crypto creates friction with national regulatory frameworks. An Australian-based operator may deal with customers, wallets, and transactions originating in dozens of countries, many of which lack comparable AML/CTF regimes.

Tranche 2 compliance obligations could require:

1. Sanctions screening and jurisdictional risk assessments
2. Reporting cross-border transfers and suspicious activity
3. Potential blocking of certain jurisdictions or wallet types

Navigating the regulatory differences between Australia, the EU, the U.S., and emerging markets presents legal and compliance minefields. Operators may need legal counsel across multiple jurisdictions and robust geofencing capabilities.

6. Resource and Capability Constraints

For large exchanges, compliance is a known cost of doing business. But for small and mid-sized operators, including new Web3 startups and DeFi projects, the cost of implementing robust AML/CTF programs may be unsustainable. Required investments include:

1. Hiring compliance officers or legal counsel
2. Procuring blockchain analytics tools (e.g., Chainalysis, Elliptic)
3. Developing policies, training modules, and audit functions

Smaller firms could face consolidation pressures or choose to exit the Australian market altogether, potentially stifling innovation and pushing activity to less-regulated environments.

7. Enforcement Risks and Reputational Impact

With AUSTRAC and other regulators stepping up enforcement, non-compliance is not an option. Tranche 2 will likely bring:

1. Increased audits and inspections
2. Higher penalties for AML/CTF failures
3. Reputational fallout for non-compliant platforms

For crypto operators, where public trust is essential in a still-maturing market, a single compliance failure could cause long-term brand damage. Proactive compliance will not just be a legal requirement — it will be a market differentiator.

Conclusion

Tranche 2 represents both a challenge and an opportunity for Australia’s digital currency industry. While it imposes new costs and constraints, it also provides a framework for legitimacy, investor protection, and integration with global financial systems.

Crypto operators should not wait for legislation to be finalised before acting. Early investment in compliance infrastructure, risk frameworks, and customer education will position forward-thinking platforms for long-term success.

The digital currency space thrives on innovation — and with the right mindset, operators can meet the Tranche 2 challenge not just with compliance, but with leadership.
