Mortgage Fraud Hits $4bn: What Borrowers Should Know

A national broker misconduct register is gaining momentum as alleged mortgage fraud at major lenders swells to $4 billion — here's what it means for you.

Australia's mortgage industry is confronting a significant reckoning. The scale of alleged fraud at the nation's largest lenders has grown to an estimated $4 billion in home purchases across the major banks, according to reporting cited by MPA Australia. The industry's response is now taking shape — and borrowers deserve to understand what has happened, how the system already protects them, and what changes are being proposed.

How the Alleged $4 Billion Fraud Unfolded

The issue first attracted public attention after a major bank self-reported potential mortgage fraud to police and corporate regulators. Since then, the estimated scale has grown substantially, with the Australian Financial Review reporting that the probe now covers around $4 billion across the nation's largest banks. The Australian Transaction Reports and Analysis Centre (AUSTRAC) is working with the major banks, law enforcement, and other regulators to map the full extent of what is described as an increasingly complex set of loan scams.

National Australia Bank (NAB) has publicly confirmed it referred multiple parties to the appropriate authorities and has exited or suspended a number of parties from the bank. Investigations have led to several arrests involving former bankers, brokers, lawyers, and accountants.

One of the more instructive episodes is the collapse of Sydney-based sub-aggregator Hai Money earlier in 2026. In December 2025, former bank employee turned broker Andrew W. Hu was charged with allegedly helping the so-called Penthouse Syndicate secure almost $100 million in fraudulent mortgage and business loans. Fourteen brokers were subsequently removed from Hai Money's network after NAB suspended their accreditations. When Hai Money's parent company later terminated its contract over reputational concerns, the sub-aggregator collapsed — leaving more than 200 brokers unable to write new loans because they had lost access to their Australian Credit Licence. It is a stark example of how the alleged misconduct of a handful of individuals can destroy the livelihoods of hundreds who did nothing wrong.

Why 94% of the Industry Wants a Broker Register

In response to escalating fraud concerns, the Australian Financial Crimes Exchange (AFCE) — an independent body that co-ordinates intelligence and investigation of financial crimes — is developing a portal to record the names of brokers who meet a specific threshold of non-compliant behaviour. The register may later be extended to cover bank employees. AFCE's membership includes Westpac, NAB, ANZ, Commonwealth Bank, and Macquarie, among others.

An MPA Australia industry poll found 94% of mortgage professionals would support a national register, with just 6% opposed.

Industry figures broadly welcome the concept but emphasise that design matters. Tanya Sale, chief executive officer of outsource Financial, argued that a register built on strong standards and due process could help address misconduct — but it should cover bankers and accountants as well, not just brokers: "If not, it risks becoming a blunt instrument that does more harm than good."

Son Pham, managing director of Rethink Finance in Australia and a former financial planner, drew on his background to make a direct comparison with an existing regime: "I was a financial planner before this and we had such a register for financial planners." Australia already maintains a Financial Advisers Register through ASIC — a public database listing each adviser's authorisations, qualifications, employment history, and any disciplinary outcomes. A similar framework for mortgage brokers would give borrowers the ability to verify a broker's standing before engaging.

The Mortgage & Finance Association of Australia (MFAA) has been explicit that fraud allegations should not be read as an indictment of the profession as a whole. MFAA executive of policy Naveen Ahluwalia noted that more than 81% of new residential home loans in Australia are now settled through a broker — market share built on genuine trust — and that the MFAA "supports strong, timely action to identify and remove bad actors" while calling for any new measures to be targeted and evidence-based.

What Borrowers Should Actually Do

For the overwhelming majority of borrowers, the fraud saga changes very little in practice. The vast majority of mortgage brokers operate ethically and are subject to rigorous compliance requirements, including the Best Interests Duty and responsible lending obligations. That said, the current environment is a useful prompt to approach your home loan process with open eyes.

**Verify credentials.** Ask which professional association your broker belongs to — the MFAA or the Finance Brokers Association of Australia (FBAA) — and confirm they carry appropriate professional indemnity insurance. Both associations maintain publicly accessible member directories.

**Understand every document request.** Legitimate brokers will explain clearly why each document is needed and maintain proper file notes throughout the process.

**Scrutinise referral relationships.** If a broker was introduced via an accountant or real estate agent and something doesn't add up, ask questions. FBAA chief executive Leo Gagic said brokers must carry out strong due diligence on loans referred by third parties — and if the information doesn't stack up, walk away.

**Use this as a prompt to check your rate.** Whether you're buying or [refinancing](/home-loans/refinance), check the [cheapest home loan options](/home-loans/cheapest) to ensure you are on a competitive rate. [First home buyers](/home-loans/first-home-buyer) in particular benefit from understanding what a compliant, well-run application looks like before starting out — and a [borrowing power calculator](/calculators/borrowing-power) is a good place to begin.

FBAA's Gagic summed it up well: "Clients understand there are bad actors in every sector but will look past negative headlines when they have first-hand experience of the excellent service brokers provide." A professional broker explains the process clearly, answers questions honestly, and consistently works in your genuine interest.
