In the first half of 2025, Australia witnessed a significant data breach involving Vinomofo Pty Ltd, an online wine retailer. The Office of the Australian Information Commissioner (OAIC) launched a detailed investigation into the breach, finding severe deficiencies in the company’s data security practices. This breach exposed the personal information of nearly one million customers, highlighting a serious lapse in privacy governance and security controls.
The breach occurred during a large-scale data migration, and the OAIC determined that Vinomofo had failed to comply with Australian Privacy Principle (APP) 11.1, which mandates the protection of personal information.
Commissioner Finds Insufficient Safeguards for Personal Data
The OAIC’s investigation revealed that Vinomofo had significant weaknesses in its internal privacy governance. Key findings included:
- Inadequate staff training and awareness around data protection.
- Weak organizational policies on privacy and data security.
- A lack of a proactive risk management approach, particularly during critical data migration activities.
Privacy Commissioner Carly Kind emphasized that organizations, especially those relying on cloud infrastructure, must implement robust security measures and proactive risk management to safeguard customer data.
Scope and Impact of the 2022 Breach
The breach occurred in 2022 during a data migration process involving over 17GB of sensitive customer data. This data included:
- Personal identifiers
- Contact details
- Financial information
Despite the company’s awareness of security vulnerabilities, its remedial actions were insufficient to prevent unauthorized access or disclosure of this sensitive information. Nearly 928,760 customers were affected, and the breach exposed critical personal data, leading to regulatory action by the OAIC.
The breach highlights the significant risks associated with data migration projects, which require enhanced security protocols to prevent data loss or unauthorized access.

New Resource for Monitoring Breach Trends: The NDB Dashboard
In response to the increasing number of breaches, the OAIC launched a new Notifiable Data Breaches (NDB) Dashboard. This interactive tool allows organizations to monitor breach trends and analyze risks across sectors in real-time. Key features of the dashboard include:
- Sector-wise breach data: Insights into breach frequency and types across various industries.
- Real-time updates: Dashboards updated twice a year to reflect the latest breach notifications.
- Educational focus: Encourages organizations to learn from past breaches and improve their data protection practices.
The OAIC encourages organizations to utilize the dashboard for better incident response and enhanced security frameworks.
