Australian Anti-Money Laundering and Counter-Terrorism Financing (AML/CTF) rules require lenders, conveyancers, and (from 2026) real estate agents to verify the source of funds for every property purchase. The verification is invisible to most buyers using a standard salary and bank deposit, but it can stall settlements where buyers are using inheritance, gift money, cryptocurrency proceeds, business sale proceeds, or significant cash. Get the documentation wrong and settlement is delayed. Get it really wrong and reportable suspicious activity reports can flow to AUSTRAC.
This guide covers the AML/CTF framework for property purchases, what documentation is required for different fund sources, and how to ensure smooth settlement.
The framework — who has obligations
Under the Anti-Money Laundering and Counter-Terrorism Financing Act 2006 (Cth):
- Banks and lenders. Comprehensive obligations. Verify identity, source of funds, and source of wealth.
- Conveyancers and solicitors. Increasing obligations. Verify identity and document funds at settlement.
- Real estate agents (from July 2026). New tranche 2 obligations include source-of-funds verification for cash transactions and high-value purchases.
Source of funds documentation by source
| Source | Verification difficulty | Documents typically required |
|---|---|---|
| Salary savings | Low | Bank statements, payslips |
| Property sale proceeds | Low | Settlement statement |
| Inheritance | Moderate | Probate, deceased estate distribution statement |
| Family gift | Moderate | Statutory declaration, donor’s bank statements |
| Business sale proceeds | Higher | Sale contract, accountant statements, ATO records |
| Investment proceeds (shares, super) | Moderate | Trade confirmations, fund statements |
| Cryptocurrency proceeds | High | Exchange statements, transaction history, KYC records |
| Overseas funds | High | Source country bank statements, FIRB approval if foreign |
| Loan from related party | High | Loan agreement, lender source verification |
| Significant cash | Very high | Detailed history; potential AUSTRAC reporting |
The $10,000 cash threshold
Cash transactions of $10,000 or more must be reported to AUSTRAC as Threshold Transaction Reports. Property settlements rarely involve cash — funds typically flow electronically through the PEXA platform — but cash deposits to support purchases trigger scrutiny.
Multiple smaller cash deposits totalling more than $10,000 (“structuring”) is a criminal offence regardless of the legitimacy of the underlying funds. Always deposit funds in single transactions when reasonable.
Inheritance and gift documentation
Inheritance verification typically requires:
- Grant of probate or letters of administration
- Distribution statement from the executor or administrator
- Death certificate
- Bank records showing receipt
Family gifts require:
- Statutory declaration from the donor (genuine gift, no expectation of repayment)
- Donor’s bank statements showing source of gift funds
- For larger gifts (over $50,000), additional verification of donor wealth source
Lenders frequently require gift letters in standard format. The donor signs a statutory declaration confirming the gift is unconditional.
Cryptocurrency proceeds — the increasingly common case
Buyers using crypto proceeds face the strictest verification:
- Full transaction history showing crypto acquisition (date, price, source)
- Exchange KYC records confirming identity
- Conversion statements showing crypto-to-AUD conversion
- Bank records showing AUD receipt
- Tax documentation showing CGT treatment of disposal
Lenders often require the funds to have been in the buyer’s bank account for 90+ days before settlement. Sudden large deposits from exchanges trigger compliance review.
What can go wrong
- Settlement delay.Insufficient documentation means lender or conveyancer can’t complete verification. Settlement pushed back days or weeks.
- Funds frozen.Banks can freeze accounts pending AML verification. Settlement can’t proceed until released.
- Reportable transactions. Suspicious matter reports flow to AUSTRAC. Investigation can take months.
- Loan declined.If source of funds can’t be verified, lenders refuse to fund.
Best practice — preparing documentation
- Plan 3+ months ahead. Funds in the bank for 90+ days are the lowest-friction option.
- Keep all paperwork. Inheritance documents, gift letters, sale contracts, exchange statements — all may be required.
- Use traceable transactions. Avoid cash where possible. Electronic transfers leave audit trails.
- Disclose proactively. Tell your conveyancer about complex fund sources before contract signing, not at settlement.
- Don’t structure deposits. Single large transactions are less suspicious than multiple smaller ones.
