Kickbacks and Secret Commissions: Tracing Payments

How Kickbacks and Secret Commissions Work

A kickback gives an agent a private reward for favouring a supplier, developer or other payer. The agent can be an employee choosing suppliers, a consultant arranging a deal or a buyer’s agent recommending property.

One arrangement starts with an inflated invoice or an overstated claim about quality. The principal pays more than the work warrants. The supplier returns part of that gain to the agent who selected it. Other arrangements reward an award of work at an ordinary price, so overcharging is one possible mechanism.

The benefit can reach the agent through several routes:

• Cash handed over after the supplier receives payment.
• A transfer to a relative or another person nominated by the agent.
• An invoice from the agent’s consultancy company for work that was never performed.
• Travel, goods or another benefit paid for by the supplier.

A genuine consultancy invoice needs evidence of the work and the agent’s authority to accept the fee. Compare the engagement, deliverables and payment terms with the agent’s role in selecting the supplier. For the wider contract-award evidence, examine procurement fraud indicators.

Property Buyer’s Agents

A buyer’s agent has a conflict if a developer secretly pays them for directing their client to a property. A selling agent’s undisclosed referral payment raises the same concern. The buyer pays for advice without knowing that the adviser gains from the recommended transaction.

State rules differ, and disclosure does not make every payment permissible:

Jurisdiction	Relevant property-agent rule	What to examine
New South Wales	Section 47 of the Property and Stock Agents Act 2002 requires disclosure of specified referral relationships and benefits.	The referral disclosure and the buyer’s acknowledgement. NSW buyer’s-agent rules also prohibit payment for referring the buyer to a selling agent.
Victoria	Section 49A of the Estate Agents Act 1980 requires a rebate statement in the written engagement. Sections 48A to 48C govern return of rebates.	The provider and amount or estimate of any relevant rebate, including a non-cash benefit. Disclosure does not authorise retention of a rebate payable to the client.
Queensland	Section 157 of the Property Occupations Act 2014 requires specified benefits and referral relationships to be disclosed to prospective residential-property buyers.	Whether the approved form was acknowledged before the sale contract. Examine the benefit’s treatment under the section, including the seller-commission exception.

The NSW disclosure form describes the section 47 requirements for buyer’s agents. NSW Government guidance confirms the prohibition on selling-agent referral payments. The Victorian Act and Queensland Act set out their different statutory requirements.

Secret Commissions Offences in Australia

Corruptly giving and receiving an agent’s reward can both be offences under Australian secret-commission laws. An offer or solicitation can be enough, even if no money changes hands.

Jurisdiction	Main provision	Maximum imprisonment for an individual on indictment
New South Wales	Crimes Act 1900, section 249B: corrupt commissions or rewards, covering the agent and the payer.	Seven years.
Victoria	Crimes Act 1958, section 176: corrupt receipt or solicitation of valuable consideration and its corrupt giving or offering.	Ten years.
Queensland	Criminal Code, sections 442B and 442BA: receipt or solicitation of a secret commission and its gift or offer. Section 442I sets the penalty.	Seven years.

The NSW Judicial Commission’s offence table distinguishes the indictment maximum from lower Local Court limits. The Victorian Crimes Act and Queensland Criminal Code contain the other provisions. Corporate fines and the penalty imposed in a particular case follow separate rules.

Disclosure and Informed Consent

Full disclosure and the principal’s informed consent are central to whether an agent may retain a commission without breaching fiduciary duty. The disclosure must explain the actual benefit and conflict sufficiently for the principal to decide. A vague statement that commissions might be paid leaves that question unresolved.

In Grimaldi v Chameleon Mining NL (No 2) [2012] FCAFC 6, the Court found a breach where a commission lacked fully informed consent. Calling the shares a gift did not answer the fiduciary claim.

For criminal liability, apply the elements of the particular offence, including corrupt conduct or dishonesty. Disclosure is relevant evidence, not a universal statutory defence that automatically defeats every charge. A principal’s consent also cannot override a separate prohibition on receiving a particular payment.

Commonwealth Officials and Disguised Invoices

Section 141.1 of the Commonwealth Criminal Code covers dishonestly giving and receiving bribes involving Commonwealth public officials. The individual maximum is ten years’ imprisonment, a fine of 10,000 penalty units or both. Section 142.1 separately covers corrupting benefits, with a five-year imprisonment maximum. These provisions concern Commonwealth officials, so they do not replace state secret-commission laws for ordinary private purchasing arrangements. The Commonwealth Criminal Code supplies the offence elements.

Division 490 can apply to invoices that disguise a kickback. Section 490.1 requires intentional false dealing with an accounting document to facilitate, conceal or disguise an illegitimate benefit or loss. A specified jurisdictional connection must also exist, such as an accounting document kept to record Australian currency.

The individual maximum is ten years’ imprisonment, 10,000 penalty units or both. The reckless offence in section 490.2 has a five-year maximum and a 5,000-penalty-unit fine. The accounting-document provisions explain those requirements.

An invoice labelled consulting is therefore an investigative lead. Establish what the document says, what work occurred and why the payment was made before classifying it as a disguised commission.

Civil Remedies Against the Agent and the Payer

A principal can seek recovery of an agent’s unauthorised profit and compensation for loss caused by the breach. Rescission can also undo a tainted contract where its requirements are met. The principal need not treat a criminal investigation as the only route to recovery.

An account of profits addresses the benefit the agent obtained. Equitable compensation addresses the principal’s loss. Keep separate calculations for the commission and any overpayment or other loss, because the same amount cannot be recovered twice.

Rescission has practical limits. Delay, affirmation of the contract or intervening third-party rights can defeat it. The ability to restore what each party received also matters.

The payer can face liability for participating in the bribe or knowingly assisting the agent’s breach. Knowing assistance requires the applicable knowledge and participation, not merely proof that the payer dealt with the agent. Preserve communications showing who proposed the payment and what the payer knew about the agent’s obligations.

Grimaldi discusses both participant liability and remedies, including discretionary proprietary relief over a bribe or its traceable proceeds. An available constructive trust does not mean every secret commission automatically creates one. The remedy depends on the facts and competing rights. For the underlying relationship, examine the fiduciary duties breached by an agent.

Tracing Kickback Payments in Bank Statements

Trace kickbacks by matching the supplier’s receipts to later payments reaching the agent, an associate or an intermediary. Repeated timing and a consistent share of invoices can reveal an arrangement hidden behind ordinary transaction descriptions.

Start with the principal’s payments and identify the supplier’s corresponding credits. Search the following days for transfers to the agent or related accounts. Allow for batch payments, refunds and split transfers, because an exact one-payment match can miss the route.

Then compare the amount reaching the suspected recipient with the invoice paid. Calculate the percentage against the same base throughout, distinguishing gross invoices from amounts excluding tax. An apparent rate can change if one invoice includes a credit note or several payments settle it.

A Hypothetical Percentage Pattern

In this fabricated example, all amounts are Australian dollars. The comparison uses gross invoice payments consistently.

Supplier receipt from the principal	Later transfer to the manager’s consultancy	Elapsed time	Transfer as a share of receipt
$20,000	$1,000	Two days	5%
$36,000	$1,800	Three days	5%
$14,000	$700	Two days	5%

The repeated 5% share supports an inference of a commission arrangement. Test it against the consultancy agreement and evidence of services. An agreed legitimate fee can also follow a percentage formula. The concealment, authority and business decision determine what the pattern means.

For cash, compare supplier withdrawals with deposits into the agent’s account after each supplier payment. Record the delay and amount, including deposits split across several entries. A nearby withdrawal and deposit support a possible connection, but cash loses a direct account-to-account identifier. Corroborate the route with receipts or communications and test other explanations for the deposit.

A relative’s account or company can be an intermediate step. Follow the onward transfer and document the relationship instead of assuming that the first recipient is the final beneficiary. Mapping payment relationships puts the people and companies alongside the transaction chain.

Turning the Statement Bundle Into Usable Evidence

FinTrace saves forensic accountants and investigators hours of statement conversion and review, leaving more time to interpret the suspected payment arrangement. The service consolidates large PDF bundles into a searchable Excel ledger and flags suspicious transfers or cash activity in a readable findings report. Every finding cites the source PDF filename and page, so the supporting statement is already at hand.

In one recent matter, review estimated at roughly 50 hours of manual lawyer work was delivered in about 10 hours. FinTrace uses advanced AI workflows with source-grounding checks and independent reviews to preserve transaction facts across the supplied records. Forensic accountants can use the consolidated ledger for their own percentage comparisons and wider analysis.

FinTrace performs this statement-analysis work at a fraction of the cost of manual review or engaging a forensic accountant for the same task. Matters receive a written quote based on a fixed base fee plus a per-page component. Request a matter assessment with the matter outline, approximate page and account counts and timeframe. Statements follow assessment and acceptance of the quote.

Build the investigation around the complete payment chain, the agent’s decision and the disclosure records. That combination lets you distinguish a suspicious pattern from an authorised fee and identify the next evidence needed to establish the arrangement.
