Australia’s financial crimes watchdog AUSTRAC has uncovered coordinated mortgage fraud worth at least $4 billion across the country’s five largest banks. An investigation called Operation Claw found borrowers inflated incomes, falsified employment records, and used shell companies to obtain loans. AUSTRAC has referred around 200 mortgage brokers, lawyers, accountants, and companies to police and regulators. The fraud predominantly targeted Sydney properties and involved funds flowing from China through illegitimate channels.

How the fraud worked

Borrowers used fake payslips, fabricated invoices, and shell companies to conceal the true source of funds. AUSTRAC found ineligible borrowers attempted to move money into Australia from China through illegitimate means. The same mortgage brokers, accountants, and law firms appeared repeatedly across multiple fraudulent applications, suggesting coordinated activity rather than isolated cases.

Scale of the problem across banks

Analysis of data from 10 major Australian banks identified the fraud was not limited to one lender or borrowing group. The suspicious activity was predominantly linked to Sydney properties and involved falsified or misleading documents. Warning signs appeared consistently across banks that together cover the vast majority of Australia’s mortgage market, according to AUSTRAC CEO Brendan Thomas.

What happens next

AUSTRAC has referred hundreds of individuals and entities to police, tax authorities, and ASIC for investigation. The watchdog is writing to 143 participants across the $2.5 trillion mortgage market urging tighter lending controls. Participating banks are now working to crack down on fraudulent loans and reviewing their loan books for similar vulnerabilities.

Why this matters for lenders and borrowers

AUSTRAC warned the fraud exposed systemic weaknesses that could be exploited for money laundering. The watchdog said the most effective way to stop mortgage fraud is before a loan is approved, once funds move, recovering money becomes difficult. Lenders must strengthen verification of income, employment, and the source of funds used for property purchases and mortgage payments.

Final Thoughts

The $4 billion fraud scandal reveals critical gaps in Australia’s mortgage lending safeguards. Banks face pressure to overhaul verification processes before approving loans, or risk further regulatory action and reputational damage.
