Key Takeaways
- AUSTRAC permits delayed initial CDD for real estate where completing initial CDD before the fall of the hammer would disrupt the ordinary course of business.
- For real estate specifically, AUSTRAC states a real estate agent brokering the sale, purchase or transfer may complete initial CDD on the buyer/transferee 28 days after the exchange of contracts, or at least 3 days before the initially agreed day for settlement (whichever is earliest).
- The standard delayed CDD timeframe in AUSTRAC guidance is 20 business days; the real-estate-specific rule is more generous in some scenarios and must be calculated against the contract/settlement dates.
- You must still have AML/CTF policies that enable initial CDD to be completed as soon as reasonably practicable.
- Delayed CDD is not a licence to put CDD off just because it's inconvenient — AUSTRAC is explicit on that.
- You don't need CDD on every bidder, only on the successful purchaser (your customer).

Why auctions are treated differently The AUSTRAC rule for real estate delayed CDD How the 28-day / 3-days-before-settlement rule works What parts of CDD you can delay Delayed CDD is not an excuse Do you need CDD on every bidder? How AMLTranche tracks the timerWhy auctions are treated differently
AUSTRAC's delayed initial CDD guidance states:
"When real estate is sold at auction, it's possible for a buyer to only be known after the fall of the hammer. You can delay initial customer due diligence (CDD) where completing initial CDD would disrupt the ordinary course of business…"
In other words: AUSTRAC accepts that at auction you don't know who the buyer will be until the hammer falls. Forcing CDD before the auction would mean CDD on every registered bidder, which is disproportionate and commercially unworkable.
The AUSTRAC rule for real estate delayed CDD
AUSTRAC's delayed initial CDD guidance contains a real-estate-specific rule:
"If you're brokering the sale, purchase or transfer of real estate — for example, as a real estate agent — you may delay completing initial CDD on the party you aren't acting for. You may complete initial CDD on the buyer/transferee 28 days after the exchange of contracts, or at least 3 days before the initially agreed day for settlement (whichever is earliest)."
This rule applies equally to:
- Real estate agents selling property at auction, where the buyer is only known after the fall of the hammer
- Real estate agents on private treaty sales, where the buyer is confirmed at exchange of contracts
- Conveyancers and legal practitioners on the same file — AUSTRAC's guidance explicitly notes the rule can apply to them too
How the 28-day / 3-days-before-settlement rule works
It's a "whichever is earliest" calculation. Two deadlines run in parallel, and you must finish initial CDD by whichever one comes first.
Worked example: 6-week settlement
- Exchange of contracts: 1 May 2026
- Agreed day for settlement: 12 June 2026 (6 weeks later)
- 28 days after exchange = 29 May 2026
- 3 days before settlement = 9 June 2026
- Deadline: 29 May 2026 (the earlier date)
Worked example: 30-day settlement
- Exchange of contracts: 1 May 2026
- Agreed day for settlement: 31 May 2026
- 28 days after exchange = 29 May 2026
- 3 days before settlement = 28 May 2026
- Deadline: 28 May 2026 (the earlier date — the 3-days-before-settlement rule is binding here)
For very short settlements, the 3-days-before-settlement rule typically binds. For long settlements (off-the-plan, complex contracts), the 28-days-after-exchange rule typically binds.
What parts of CDD you can delay
AUSTRAC's guidance allows you to delay verification of specific KYC information where appropriate. You must still collect the information from the customer through your onboarding process. Matters you may be able to delay verification of include:
- Identity details of the customer
- Identity of any beneficial owners of the customer
- Whether the customer, any beneficial owners, any person on whose behalf the customer is receiving the designated service, or any person acting on behalf of the customer is a politically exposed person (PEP) or person designated for targeted financial sanctions (TFS)
You collect the same information from the customer as you ordinarily would through your onboarding form. You identify the ML/TF risk based on the information collected. You then verify as soon as reasonably practicable, within the applicable timeframe.
Delayed CDD is not an excuse to put CDD off
AUSTRAC is explicit on this
"It isn't a sufficient reason to delay initial CDD because it would be inconvenient for you or the customer to do it before you provide the designated service." — AUSTRAC delayed initial CDD guidance
Practical translation: the auction delay exists because it's impossible to CDD a buyer who hasn't been identified yet. It does not apply to cases where CDD could be done in advance but wasn't. AUSTRAC also requires your AML/CTF policies to describe:
- The circumstances in which delayed CDD is appropriate
- How you will manage and mitigate the ML/TF risks that arise from the delay
Do you need CDD on every registered bidder?
No. You provide a designated service to the buyer — the successful purchaser — not to every registered bidder.
Per AUSTRAC guidance, CDD is required on each person to whom you provide a designated service. At auction:
- Only one bidder becomes the buyer (the successful purchaser)
- CDD is required on the buyer once they are known, within the delayed CDD timeframe
- You do not need CDD on the other registered bidders
For the seller side, CDD on the vendor can and should be completed before the auction campaign begins — there's no auction-related reason to delay CDD on the vendor.
How AMLTranche tracks the auction and exchange timer
For real estate files, AMLTranche tracks both the 28-day-after-exchange and 3-days-before-settlement dates automatically. When exchange of contracts is logged, the platform:
- Calculates both deadlines and displays whichever is earliest
- Prompts for CDD completion well before the deadline
- Alerts the compliance officer if a file is approaching the window unresolved
- Records the time-stamped CDD completion for the 7-year audit trail
Frequently asked questions
When does AUSTRAC permit delayed CDD at auction?
AUSTRAC permits delayed CDD for real estate where completing initial CDD before the fall of the hammer would disrupt the ordinary course of business. Delayed CDD is not permitted just because it's inconvenient.
How long do I have to complete CDD after an auction?
Per AUSTRAC's delayed initial CDD guidance for real estate: 28 days after the exchange of contracts, or at least 3 days before the initially agreed day for settlement — whichever is earliest.
What if the settlement date is less than 28 days after exchange?
Then the 3-days-before-settlement rule binds. For example, if exchange is 1 May and settlement is 15 May, you must complete CDD by 12 May (3 days before settlement), not 29 May.
Do I need CDD on every bidder at an auction?
No. You provide a designated service to the buyer (successful purchaser), not to every registered bidder. CDD is required only on the buyer, within the delayed CDD timeframe.
Can conveyancers use the same delayed CDD rule?
AUSTRAC's guidance extends the real-estate delayed CDD rule to legal practitioners and conveyancers assisting a client who is the buyer of real estate — same 28-days-after-exchange or 3-days-before-settlement rule.
Can I delay CDD on the seller too?
No. There is no auction-related reason to delay CDD on the seller/vendor. CDD on the vendor should be completed before the auction campaign begins.
