AUSTRAC uncovers coordinated mortgage fraud across 10 major banks

A wake-up call across the mortgage market

The same forged payslip. The same invented employer. The same broker appearing on loan files at three different banks. A joint analysis of data from 10 major Australian banks has identified potentially hundreds of millions of dollars in suspected fraudulent loans, most of them linked to properties in Sydney.^[1] The scale of what investigators found, repeated across institutions that together cover the bulk of Australia's mortgage market, is what sets this apart from a routine fraud case.

AUSTRAC's financial intelligence partnership, the Fintel Alliance, ran the investigation under the name Operation Claw.^[1] The Fintel Alliance is a public-private partnership between AUSTRAC, Australian banks and law enforcement agencies, built to pool data and identify financial crime patterns that no single institution would catch on its own.

How the fraud worked

Operation Claw identified suspected mortgage fraud involving inflated incomes, misrepresented employment and fabricated or unverifiable business activity, as well as cases where offshore or third-party funds were used to complete property settlements and mortgage repayments.^[1] Fraudsters were not simply lying about their salary. They were constructing entire financial identities: a business that cannot be verified, an employer who does not exist, and funds arriving from offshore at settlement to plug gaps a forged payslip could not cover.

That kind of layered deception is designed to survive a basic credit assessment. Individually, each document might pass. Across a portfolio, with 10 lenders sharing data at the same time, the repetition becomes visible.

Warning signs that crossed lender boundaries

Investigators found recurring patterns that no single bank's internal controls had caught on their own. Across participating banks, the warning signs included falsified or misleading documents and the repeated use of the same mortgage brokers, accountants and law firms across multiple loan applications.^[1] When the same professional intermediary appears on suspicious files at several different lenders, it points to a coordinated referral network rather than isolated individual fraud.

AUSTRAC CEO Brendan Thomas said the findings should prompt every lender in Australia to reassess its controls. Thomas said, "The scale of this activity should be a wake-up call for every lender. The same warning signs were found across banks that together cover the vast majority of Australia's mortgage market."^[1]

Thomas was direct about what comes next. Thomas said, "Lenders need to actively look for these warning signs, strengthen their controls and report suspicious activity to AUSTRAC. This is not something any institution can afford to ignore."^[1]

Who else is now involved

Operation Claw drew in a wide range of agencies beyond AUSTRAC and the banks. The investigation involved the Australian Taxation Office, NSW Police Force, NSW Crime Commission, the Australian Criminal Intelligence Commission, APRA and ASIC throughout the process.^[1] The inclusion of the Tax Practitioners Board alongside the ATO signals that professional enablers of the fraud, not just borrowers, are inside the scope of ongoing scrutiny.

The Fintel Alliance has provided names of individuals and entities potentially involved in the submission of false documents to ASIC, the ATO, the Tax Practitioners Board and NSW Police, for intelligence purposes.^[1] Referrals for intelligence purposes do not automatically translate into charges, but they place those individuals and firms under active scrutiny across multiple agencies at once.

What banks have already done, and what they must do now

Participating banks have not been passive since the investigation concluded. Using intelligence from Operation Claw, the 10 lenders have already identified potentially fraudulent loans, investigated suspicious activity, strengthened internal controls, ended some banking relationships and made further referrals to authorities.^[1] Ending banking relationships is a significant step, meaning at least some of the individuals and entities named in the investigation no longer have access to the lending system at those institutions.

AUSTRAC's formal direction to lenders is clear: actively look for the warning signs Operation Claw documented, tighten controls around document verification, and report suspicious mortgage applications to AUSTRAC rather than simply declining them. Declining a loan stops one transaction; reporting it generates intelligence that can identify a network.

Where this started, and how big it has become

The Fintel Alliance findings escalate a problem the banks themselves surfaced. Broker trade publications The Adviser and Broker Daily report that the saga began earlier this year when Commonwealth Bank alerted regulators and police to concerns inside its own home-loan portfolio. What was first estimated as a $1 billion problem has since reportedly grown to at least $4 billion in lending across the country's five largest banks.

Those outlets also report that investigators have raised concerns about criminals using artificial intelligence to generate the documents used to obtain mortgages fraudulently, which would make the falsified payslips and employment records described by AUSTRAC cheaper and faster to produce at scale.

The Australian Financial Review has reported, and Bushletter has not independently verified, that some ineligible borrowers sought to move money into Australia from China through illegitimate channels, using shell companies, fabricated invoices and false payslips to disguise the true source of funds. The AFR also put the number of referrals to other agencies at about 200.

What the banks say

The banking industry publicly welcomed the operation. Australian Banking Association chief executive Simon Birmingham told the ABC that the sector would keep working with law enforcement and regulators, and pointed to the information-sharing arrangement as the reason the fraud surfaced at all.

This work has included intelligence sharing between banks and AUSTRAC through the Fintel Alliance, which has already proven effective in uncovering fraudulent loan activity.

That is the mechanism Thomas returned to as well. Each bank, he said, may see only one fragment of a pattern, and mortgage fraud succeeds precisely when those fragments stay disconnected.

What it means for borrowers and brokers

For honest borrowers, the near-term consequence is friction: more documentation, more verification of income and employment, and more questions about where a deposit came from. That lands on a market where credit was already tightening and values fell 0.7 per cent in July. Commonwealth Bank reported investor loan applications down 28 per cent since the budget, and NAB reported home loan applications down 15 per cent on the previous quarter.

For mortgage brokers, the reputational exposure is sharper. AUSTRAC did not name any broker, accountant or law firm, and no findings have been made against any individual referred for intelligence purposes. But the regulator was explicit that the same intermediaries recurred across multiple suspicious applications at different banks, which is what turned scattered cases into a pattern.

The money laundering question

One important qualification sits inside the AUSTRAC findings. Brendan Thomas said, "While this project did not identify evidence of widespread money laundering, the weaknesses it exposed could be exploited by criminals seeking to abuse Australia's financial system."^[1]

Mortgage fraud and money laundering are separate offences. Fraud means obtaining credit through deception; money laundering means moving illicit funds through the financial system to disguise their origin. AUSTRAC found the former at scale without confirming the latter is widespread, but warned clearly that the same infrastructure enabling coordinated mortgage fraud is what organised crime would need to move dirty money through Australian property.

For ordinary borrowers and property buyers, the findings are a reminder that mortgage intermediaries, including brokers, accountants and conveyancers, are now under active regulatory scrutiny. Anyone involved in a transaction where funding sources were unusual or documentation was prepared by a third party should expect greater verification demands from lenders going forward. AUSTRAC's referrals to NSW Police, ASIC and the ATO remain active as of the date of publication.
