$557 million stolen through fake myGov accounts in a single year. Criminals figured out they could create a myGov account, link it to someone else's tax file number, and lodge a fraudulent tax return — collecting the refund before the real person even knew. The Inspector-General called the system "fundamentally flawed." Half a billion dollars says he was right. The government used myGov's data-matching infrastructure to compare ATO tax records with Centrelink payments — then sent automated debt notices to 443,000 people. Many debts were wrong. The scheme was illegal from day one. People killed themselves over debts they never owed. The Royal Commission called it "a crude and cruel mechanism." The government repaid $1.76 billion. The dead did not come back.
What they claim: myGov states Adobe Experience Platform has been "set up to operate on myGov without collecting information that identifies you."
What we found: The myGov app uses Adobe Experience Platform with a unique identifier called an "Adobe Experience Cloud ID" assigned to each user. It also uses Google Analytics 360. While myGov claims these don't identify users, Adobe assigns a persistent unique ID that tracks all interactions across sessions. Additionally, "authorised staff can play back user interactions" — meaning your navigation through Centrelink, Medicare, tax, and child support is recorded and reviewable.
What they claim: myGov states "personal information will be stored securely in Australia" and biometric images are "destroyed within 14 days."
What we found: The OAIC found that iProov, a UK-based third party, may hold biometric information for 14 days "in circumstances where the image is suspicious or inconclusive" and may use it for "performance validation and testing purposes." In cases where the real person check fails, "a biometric image may be viewable by a contracted third-party in the United Kingdom." Australian citizens' facial biometrics are being sent offshore to a private UK company that can use them for testing.
What they claim: myGov privacy policy describes data sharing between linked services as necessary for service delivery
What we found: Data matching between ATO income data and Centrelink records through myGov infrastructure was the mechanism behind the illegal Robodebt scheme, which issued $1.76 billion in unlawful debts to 443,000 Australians. A Royal Commission found the scheme was illegal from inception and contributed to suicides.
What they claim: myGov privacy policy states data is collected only for service delivery purposes
What we found: The myGov app requests device identifiers, advertising ID access, and uses Google Analytics tracking. A 2023 OAIC assessment found the app collected more metadata than necessary for authentication, including device fingerprinting data that persisted across sessions.
What they claim: myGov is promoted as the inclusive digital gateway for all Australians
What we found: A 2023 Senate inquiry found myGov was "not fit for purpose" for elderly, disabled, and digitally illiterate Australians. Witnesses described elderly people crying in Services Australia offices because they could not navigate the app. The Digital Transformation Agency acknowledged that 5.7 million Australians lack basic digital literacy.
What they claim: The Australian Government is pushing "digital first" service delivery, with myGov app now handling over one-third of 864,000 average daily sign-ins and logging 122 million sign-ins in 18 months.
What we found: While pushing citizens onto digital platforms, Services Australia admitted the platform was designed in 2013 and its security had not kept pace with threats. The Ombudsman found security was "not adequate." Multi-factor authentication for high-risk transactions was not implemented until recommended by the Ombudsman in 2024. Passkeys were only introduced in July 2024. The government pushed 5.6 million people onto an app while knowing its security architecture was a decade out of date.
What they claim: myGov promotes strong security protections and states "your privacy is protected by law."
What we found: The Commonwealth Ombudsman's August 2024 report "Keeping myGov Secure" found security measures "did not adequately protect people" from fraud. Over 10,000 people reported misuse of their myGov accounts in 12 months — double the previous year. Fraudsters stole $25.5 million through fake tax returns by exploiting "unauthorised linking" vulnerabilities. Services Australia admitted the "cyber threat landscape has deteriorated substantially since myGov was first designed and implemented in 2013."
What they claim: Services Australia promotes myGov as secure and states it keeps "peoples information secure" with "strong security processes and protections."
What we found: Services Australia reported 43 data breaches involving impersonation or social engineering between January and July 2024 alone — a 330% increase from 10 such breaches across all of 2023. The agency was dealing with "more than 300 scams per week impersonating myGov" and saw "coordinated fraud activity operating in an opportunistic and systematic way." Staff in some cases failed to ask required security questions, enabling fraudsters to change bank details and lodge false claims.
What they claim: myGov promotes the convenience of linking all government services — Centrelink, Medicare, ATO, Child Support, My Health Record, NDIS — in one place.
What we found: This single-point-of-access design means that when a myGov account is compromised, attackers gain access to tax records, health claims, welfare payments, child support, and disability services simultaneously. The Ombudsman found fraudsters exploited "unauthorised linking" to connect victims' Medicare and Centrelink accounts to fake myGov accounts, enabling multi-service fraud. One compromised account gives access to a citizen's entire government identity.
What they claim: myGov claims robust identity verification and security measures
What we found: The ATO reported $557 million in identity fraud via myGov in the 2022-23 financial year. Criminals were creating fake myGov accounts, linking them to real tax file numbers, and lodging fraudulent tax returns. The Inspector-General of Taxation called the system "fundamentally flawed".
What they claim: Services Australia promotes myGov as a convenient 24/7 digital portal
What we found: Major outages in 2022 and 2023 locked millions out of Centrelink, Medicare and ATO services during tax time and welfare reporting periods. A Senate Estimates hearing revealed the platform had over 100 outages in a 12-month period, with some lasting over 8 hours.
