Customer Due Diligence Checklist for Australian Businesses

Customer due diligence (CDD) is a core obligation under the AML/CTF Act 2006. This guide covers every element of the CDD process — from initial identification through to ongoing monitoring and the 7-year record keeping requirement.

What is Customer Due Diligence (CDD)?

Customer Due Diligence (CDD) — also referred to as Know Your Customer (KYC) — is the process by which reporting entities identify and verify the identity of their customers, understand the nature of their business relationships, and assess the risk they pose of being used for money laundering or terrorism financing.

Under Part 2 of the AML/CTF Act 2006 and the AML/CTF Rules 2007, reporting entities must conduct CDD on customers before providing a designated service. The level of due diligence required depends on the risk profile of the customer and the nature of the service provided.

CDD is not a one-time activity. Reporting entities must also conduct ongoing customer due diligence (OCDD) throughout the business relationship — monitoring transactions, keeping customer information up to date, and re-assessing risk when circumstances change.

Standard

Applied to most customers at onboarding — identity verification with one reliable document

Simplified

Reduced verification for low-risk customers or products where risk is demonstrably low

Enhanced

Additional verification for high-risk customers including PEPs, high-risk jurisdictions, and complex structures

Standard, Simplified, and Enhanced Due Diligence

Standard Customer Due Diligence

Standard CDD applies to the majority of customers. It requires you to identify and verify the customer's identity using reliable, independent documents or data sources before providing the service. For individuals, this typically means a government-issued photo ID. For businesses, it means verifying the entity's registration details and identifying beneficial owners.

Under the AML/CTF Rules, standard verification for an individual requires collecting the customer's full name, date of birth, and residential address, and verifying at least one piece of primary photographic identification (such as a passport or driver's licence). Electronic verification through a government-linked database (DVS) satisfies this requirement.

Simplified Customer Due Diligence

Simplified CDD allows reporting entities to apply reduced verification measures where the risk of money laundering or terrorism financing is demonstrably low. However, simplified CDD is not an exemption from CDD — it is a reduction in the level of verification required.

Simplified CDD may be appropriate for customers that are themselves regulated financial institutions, listed public companies, government bodies, or products that are low-risk by design (such as low-balance prepaid cards with no cash withdrawals).

Simplified CDD cannot be applied where there are any indicators of higher risk. If risk factors are present, you must apply standard or enhanced CDD regardless of the customer type.

Enhanced Customer Due Diligence (EDD)

Enhanced CDD must be applied when the risk assessment indicates a higher risk of money laundering or terrorism financing. Enhanced measures go beyond standard identification to require additional documentation, deeper investigation, and senior management sign-off.

EDD is mandatory in the following circumstances:

Customer is a politically exposed person (PEP) or close associate
Customer is from a high-risk jurisdiction (FATF grey or black list)
Complex or unusual corporate structures with no clear business rationale
Customer activity is inconsistent with stated purpose or profile
Transactions involve correspondent banking relationships
Customer involved in certain high-risk industries (weapons, gambling, etc.)
Source of funds or wealth cannot be readily verified
Customer refuses to provide required identification

EDD measures may include: obtaining additional identification documents, verifying source of funds and wealth, obtaining information about the purpose and intended nature of the relationship, collecting supporting financial documents, and requiring senior management approval before onboarding.

The CDD checklist

Use these checklists to ensure you are collecting and verifying all required information for individual and business customers.

Individual customers

Full legal name (matching government-issued ID)
Date of birth
Residential address (not a PO Box)
Verification of identity using reliable, independent documents
For higher risk: secondary identification document
PEP screening (politically exposed persons and associates)
Sanctions screening (OFAC, UN, Australian lists)
Adverse media check for higher-risk customers
Source of funds documentation (where required)
Source of wealth documentation (for EDD customers)

Business customers

Registered business name and trading name
Australian Business Number (ABN) or ACN
Registered address and principal place of business
Nature of business and industry sector
Directors and beneficial owners (25%+ ownership)
Verification of each director's identity
Constitutional documents (trust deed, partnership agreement, etc.)
Sanctions screening of the entity and all beneficial owners
PEP screening of directors and beneficial owners
Source of funds and source of wealth (for EDD)

Identifying beneficial ownership

For business customers, you must identify and verify the identity of all beneficial owners — any individual who ultimately owns or controls 25% or more of the entity, or who otherwise exercises effective control over the entity's decisions. This prevents criminals from using corporate structures to obscure beneficial ownership of illegal proceeds.

Beneficial ownership identification requires you to look through corporate layers to identify the ultimate natural person controllers. Where a trust is involved, you must identify the settlor, trustee(s), protector, beneficiaries, and any other natural person exercising ultimate control. Where a partnership is involved, you must identify each partner.

Where a customer is unable or unwilling to identify their beneficial owners, you must not provide the designated service. This situation may also warrant lodging a Suspicious Matter Report.

Source of funds and source of wealth

Source of funds refers to the origin of the specific funds being used in a transaction or deposited into an account. Source of wealth refers to how the customer accumulated their overall assets and net worth. Both are relevant to higher-risk customers.

Evidence for source of funds

Bank statements showing the origin
Property sale contracts
Business sale or investment documentation
Inheritance documents (will, probate)
Salary slips or employment contract
Tax returns

Evidence for source of wealth

Financial statements or accounts
Director / shareholder registers
Business ownership documentation
Audited financial statements
Investment portfolio statements
Statutory declarations for unusual wealth

Ongoing Customer Due Diligence (OCDD)

CDD does not stop at onboarding. The AML/CTF Act requires reporting entities to conduct ongoing customer due diligence (OCDD) throughout the business relationship. This means continuously monitoring customer transactions and behaviour, keeping customer information current, and re-screening against sanctions and PEP lists when changes occur.

The frequency and intensity of OCDD should be proportionate to the customer's risk rating. High-risk customers require more frequent monitoring and more comprehensive review. Low-risk customers may be subject to lighter-touch periodic reviews.

When must OCDD be triggered?

Customer information becomes outdated or is no longer current
Transaction patterns change significantly without explanation
Customer matches or near-matches a sanctions list
Customer becomes, or is identified as, a PEP
A new high-risk transaction is requested
Risk rating of the customer increases
Adverse media reporting about the customer
Customer business model or structure changes
Periodic review date is reached (based on risk rating)
Customer requests unusual account activity or higher limits

Risk-based review frequency

Risk ratingReview frequencyRe-verification
LowEvery 3 yearsOn material change only
MediumAnnuallyIf information outdated
HighEvery 6 monthsFull re-verification each cycle
PEP / EDDEvery 6 months or moreSenior management sign-off required

* These are indicative frequencies. Your AML/CTF program must specify review intervals appropriate to your risk assessment.

Record keeping requirements (7-year retention)

Under Part 10 of the AML/CTF Act, reporting entities must retain CDD and transaction records for a minimum of 7 years. The 7-year period begins from the date the record was made, or — for records relating to a customer relationship — from the date the relationship ended.

Records must be stored in a form that allows them to be accessed and reproduced quickly in response to a request from AUSTRAC or law enforcement. Tamper-evident storage (such as write-once systems or cryptographically signed records) is strongly recommended.
