Transaction Monitoring Highlights
- Meaning: A risk based program to help employees identify suspicious behaviours and transactions, and protect the business and customers.
- Why it matters: It supports suspicious matter reporting and helps meet ongoing and enhanced customer due diligence obligations.
- Where it sits: You must document how you monitor customer transactions in Part A of your AML and CTF program.
In the 2026 Australian regulatory landscape, a “set and forget” approach to customer onboarding is no longer legally defensible. Under the Anti-Money Laundering and Counter-Terrorism Financing (AML/CTF) Act 2006, transaction monitoring is a core pillar of a business’s Ongoing Customer Due Diligence (OCDD) obligations.
As the Tranche 2 reforms fully integrate sectors like law, real estate, and accounting into the law, AUSTRAC has made it clear: monitoring must be proactive, risk-based, and capable of detecting criminal patterns in real-time.
What Is Transaction Monitoring Under Australia’s AML/CTF Law?
Transaction monitoring is the ongoing process of reviewing customer transactions to identify activity that is unusual, complex, or lacks an apparent economic or legal purpose. Unlike initial KYC (Know Your Customer) checks, which verify who a person is, transaction monitoring analyzes what they are doing over the course of the relationship.
Under the Australian law, your transaction monitoring program (TMP) must be documented within Part A of your AML/CFT Program. Its primary purpose is to identify “suspicious matters” that require reporting to AUSTRAC. It is not a suggestion – it is a mandatory requirement for every reporting entity providing designated services.
Why Transaction Monitoring Is Mandatory for Reporting Entities
AUSTRAC mandates transaction monitoring because it is often the only way to detect the “Layering” and “Integration” stages of money laundering.
Key Regulatory Drivers:
- Legal Obligation: Section 36 of the Act requires reporting entities to have systems in place to monitor customers on an ongoing basis.
- Risk Mitigation: It allows your business to detect when a previously “Low Risk” client suddenly begins exhibiting “High Risk” behaviors (e.g., a domestic retail client starting to send large international wires).
- Intelligence Source: Transaction monitoring feeds the Suspicious Matter Report (SMR) system, providing law enforcement with actionable data to disrupt organized crime and terrorism.
- Accountability: Senior management must ensure the monitoring program is regularly audited and updated to reflect new criminal typologies.
Key Components of an Effective AML Transaction Monitoring Framework
An effective framework is not just a list of rules; it is a risk-based system tailored to your specific business model.
1. Risk-Based Rules and Scenarios
Rather than monitoring every transaction equally, you should set thresholds based on your AML Risk Assessment. For example, transactions involving high-risk jurisdictions should trigger alerts at lower dollar amounts than domestic ones.
2. Detection of Structuring
Your system must be able to detect “structuring” (or smurfing) where a customer breaks a large sum into multiple smaller transactions to stay under the $10,000 TTR threshold.
3. Investigation and Escalation
When an alert is triggered, your business must have a documented process for investigation. This involves comparing the transaction against the customer’s stated “Source of Wealth” and “Nature of Business.”
4. Periodic Calibration
Criminals change their tactics. AUSTRAC expects reporting entities to “tune” their monitoring rules at least annually to reduce false positives and ensure new threats (like crypto-mixing or shell company layering) are captured.
Common Red Flags Identified Through Transaction Monitoring
Reporting entities should configure their monitoring systems to flag the following “red flags”:
- Rapid Circularity: Funds deposited and immediately transferred out to unrelated third parties.
- Threshold Sensitivity: Frequent transactions just below $10,000 (e.g., $9,800 or $9,950).
- Profile Mismatch: A student or retiree receiving large, frequent business-like payments.
- U-Turning: International funds arriving from one country and being sent to another within 24–48 hours.
- Dormancy Spikes: An account that has been inactive for months suddenly facilitating high-volume transactions.
- Unusual Cash Use: High-volume cash deposits for a business that usually operates via bank transfers (e.g., a software consultancy).
Transaction Monitoring and Suspicious Matter Reports (SMRs)
The ultimate goal of monitoring is to determine if a Suspicious Matter Report (SMR) is necessary.
| Process Stage | Action Required |
|---|---|
| Alert Triggered | Compliance team reviews transaction data and customer history. |
| Initial Review | If unusual, perform Enhanced Due Diligence (EDD) – ask the client for more info. |
| Suspicion Formed | If the activity remains “suspicious on reasonable grounds,” the 3-day clock starts. |
| Lodge SMR | Submit the report to AUSTRAC Online. |
Important Note: You must conduct this monitoring and investigation without “Tipping Off” the customer. If you ask for information, do so as part of “routine account maintenance” rather than mentioning a suspicious activity alert.
Transaction Monitoring Under Tranche 2 Reforms
With the July 1, 2026 implementation of Tranche 2, the definition of “monitoring” has expanded into the professional services sector.
- Real Estate: Monitoring for multiple deposits from different third parties for a single property purchase.
- Lawyers/Accountants: Monitoring trust account activity for “pass-through” transactions where the firm is used as a temporary holding pen for funds with no legal service attached.
- Small Business Kits: AUSTRAC has released “Starter Kits” for Tranche 2 entities, which include simplified manual monitoring logs for firms with lower transaction volumes.
How to Strengthen Your Transaction Monitoring Controls
To ensure your monitoring framework survives an AUSTRAC audit in 2026, consider these proactive steps:
- Conduct a Gap Analysis: Check if your current monitoring covers all “Designated Services” you provide.
- Integrate Risk Scoring: Ensure your monitoring system “knows” who your high-risk clients are and watches them more closely.
- Staff Training: frontline staff must be trained to recognize the behavioral red flags that automated systems might miss.
- Independent Review: Schedule an external audit of your Transaction Monitoring Program every 2–3 years to verify it is “operating as intended.”

FAQs about Transaction Monitoring
Do we need software?
Not always. The expectation is appropriateness and risk basis. Smaller firms can implement practical manual controls, but they must be consistent and evidenced.
