Australia’s Cyber Crime Crisis: The Qantas Data Breach and the Urgent Need for Stronger Cybersecurity Laws, By Brian Simpson
On July 9, 2025, Qantas, Australia's flagship airline, confirmed that a cyber attack compromised the personal data of approximately 5.7 million customers. This breach, while significant, was overshadowed by the scale of previous incidents, such as the 2022 Optus hack affecting nearly 10 million people and the 2024 MediSecure breach impacting 12.9 million Australians. Despite the relatively muted public response, the Qantas incident underscores a persistent and growing issue in Australia's digital landscape: the alarming frequency of data breaches and their cascading effects on privacy, security, and trust. As highlighted by cybersecurity experts Jongkil Jay Jeon, Ashish Nandda, and Peter Thomas (link below), these breaches fuel sophisticated "convergence scams," where stolen data is weaponised to extract even more sensitive information from victims. Meanwhile, data ethicist Adam Andreotta argues that the focus on individual vigilance post-breach distracts from a critical need: stronger corporate cybersecurity laws to prevent such incidents. This blog piece explores the Qantas breach in the context of Australia's cyber crime epidemic, the rise of convergence scams, the inadequacy of current bank reimbursement policies, and the pressing need for legislative reform to bolster corporate accountability.
The Qantas breach, reported on July 2, 2025, involved a cyber attack on a third-party customer service platform used by the airline's Manila-based call centre. Cybercriminals, potentially linked to the Scattered Spider group known for social engineering tactics, accessed names, email addresses, phone numbers, dates of birth, frequent flyer numbers, and, for some customers, addresses and gender information. While Qantas stated that no financial data, passwords, or passport details were compromised, the breach affected 5.7 million customer records, a significant portion of Australia's population. The airline responded by containing the affected system, engaging cybersecurity firm CyberCX, and notifying the Australian Federal Police (AFP), the Australian Cyber Security Centre (ACSC), and the Office of the Australian Information Commissioner (OAIC). Qantas also established a dedicated support line and urged customers to remain vigilant against scams. However, the breach's scale and the airline's delayed executive response drew criticism, with experts like Phoebe Netto noting insufficiently detailed updates in the immediate aftermath.
The Qantas breach is not an isolated incident but part of a disturbing trend. In 2024, Australia recorded 47 million data breaches, making it the 11th most affected country globally, with one account compromised every second. High-profile breaches, including Optus (2022, 9.8 million affected), Medibank (2022, 9.7 million affected), and MediSecure (2024, 12.9 million affected), have exposed the personal data of nearly every Australian, some multiple times. The MediSecure breach, for instance, involved sensitive health data, while the Optus hack exposed critical identity documents like passport and driver's license numbers. These incidents highlight the vulnerability of sectors handling vast amounts of personal data, including telecommunications, healthcare, and aviation. The OAIC reported 2024 as the worst year for data breaches since records began in 2018, with Privacy Commissioner Carly Kind urging stronger security measures across public and private sectors.
The growing frequency of breaches is driven by several factors:
Sophisticated Cybercrime Tactics: Groups like Scattered Spider use social engineering, such as impersonating employees to deceive call centre staff, to bypass security measures like multi-factor authentication (MFA). The Qantas breach, for example, likely stemmed from a social engineering attack rather than a technical exploit.
Third-Party Vulnerabilities: Many breaches, including Qantas and MediSecure, involve third-party platforms or supply chains, which are often less secure than primary systems. The OAIC noted 34 multi-party breach notifications in the first half of 2024, underscoring the risks of outsourcing data handling.
Data Retention Practices: Australian laws require companies like telecommunications providers to retain customer data for extended periods (e.g., six years for Optus), creating large, vulnerable databases. Cybersecurity experts advocate reforming these retention laws to minimise stored data.
The Qantas breach, like its predecessors, provides cybercriminals with a treasure trove of personal information for "convergence scams." These scams combine data from multiple breaches to create detailed profiles, enabling fraudsters to impersonate trusted entities like banks, airlines, or government agencies. For example, a scammer might use a Qantas customer's name, phone number, and frequent flyer number to pose as a Qantas representative, tricking the victim into revealing bank passwords or one-time passcodes. Cybersecurity expert Richard Buckland warns that such data can also facilitate password resets on other platforms, amplifying the risk of account takeovers.
Stan Gallo of BDO Australia noted that the 5.7 million affected Qantas customers are prime targets for scams impersonating entities like myGov or banks. Indeed, several Qantas customers reported fraudulent attempts to access their myGov accounts post-breach, highlighting the real-world impact of convergence scams. The MediSecure and Optus breaches similarly fuelled phishing campaigns, with scammers leveraging stolen data to craft convincing communications. This trend underscores a chilling reality: even seemingly innocuous data, like email addresses or frequent flyer numbers, becomes dangerous when combined with information from other breaches.
A particularly contentious issue arising from convergence scams is the refusal of some banks to reimburse victims who "voluntarily" disclose sensitive information, such as one-time passcodes, to scammers. This policy places the burden of financial loss on individuals, despite the initial breach occurring due to corporate security failures. For example, a Qantas customer, Ms. Ganon, reported receiving a scam call referencing her personal details, likely sourced from the breach. She expressed scepticism about Qantas's claim that no financial data was compromised, noting that scammers could combine Qantas data with information from prior breaches (e.g., Medibank or Optus) to create convincing fraud schemes.
This practice raises ethical and legal questions. Victims are often unaware that their data was compromised until they fall prey to scams, yet banks argue that providing information to fraudsters constitutes negligence. Data ethicist Adam Andreotta argues that this focus on individual responsibility obscures the root issue: inadequate corporate cybersecurity. The OAIC's ongoing investigations into Medibank and Australian Clinical Labs for insufficient security practices signal a shift toward holding companies accountable, but current privacy laws offer limited recourse for victims seeking compensation.
The Qantas breach has reignited calls for legislative reform to strengthen corporate cybersecurity obligations. Australia's Privacy Act, amended in 2024, introduced stricter penalties for data breaches, but experts argue these measures are insufficient. Lizzie O'Shea of Maurice Blackburn highlights that the OAIC's complaint process is slow and overwhelmed, limiting victims' ability to seek justice. Proposed reforms, such as allowing individuals to sue companies directly for privacy breaches, have garnered public support but face implementation challenges.
Key areas for reform include:
Mandatory Security Standards: Experts like Nicholson believe that robust measures, such as MFA, encryption, and strict access controls, should be mandatory, not optional. The Medibank breach, still under federal court review, illustrates the consequences of failing to meet these standards.
Reduced Data Retention: Reforming data retention laws to limit the amount and duration of stored personal information could reduce the impact of breaches.
Third-Party Oversight: The Qantas and MediSecure breaches highlight the need for stricter oversight of third-party vendors, who are often the weakest link in corporate security.
Victim Compensation: Introducing mechanisms to ensure victims are not left financially liable for losses from convergence scams would shift accountability back to corporations.
The government's response to the Optus breach, amending telecommunications regulations to allow limited data sharing with financial institutions to prevent fraud, shows progress, but broader reforms are needed to address systemic vulnerabilities. The AFP's Operation GUARDIAN and the Commonwealth Credential Protection Register are steps toward mitigating identity theft, but they are reactive rather than preventive.
Qantas's advice to "stay vigilant" echoes the post-breach rhetoric of Optus and Medibank, placing significant responsibility on consumers to protect themselves. While enabling MFA, using complex passwords, and verifying unsolicited communications are critical, this approach unfairly burdens individuals already victimised by corporate failures. Andreotta argues that the focus on consumer caution distracts from the need for companies to invest in robust cybersecurity. Qantas CEO Vanessa Hudson claimed the airline has spent "tens of millions" on cybersecurity, yet the breach occurred due to a social engineering attack, a preventable human error. This discrepancy highlights the need for better employee training and system design to counter sophisticated cyber threats.
The Qantas data breach, while smaller than the Optus or MediSecure incidents, is a stark reminder of Australia's ongoing cyber crime crisis. With 47 million breaches in 2024 alone, the nation faces a relentless wave of cyberattacks that fuel convergence scams, exploit third-party vulnerabilities, and expose systemic weaknesses in data protection. Current bank reimbursement policies exacerbate the harm by penalising victims, while the OAIC's slow processes and limited penalties fail to hold corporations accountable. Strengthening cybersecurity laws, through mandatory security standards, reduced data retention, third-party oversight, and victim compensation, is essential to prevent future breaches and restore public trust. Until these reforms are implemented, Australians will remain vulnerable to the cascading effects of data breaches, with scammers exploiting stolen information to devastating effect.
