Case Study: Teachers Mutual Bank Limited achieves a streamlined, centralized audit process with Diligent

Growing the audit team’s impact at one of the world’s most ethical companies

Teachers Mutual Bank Limited, one of Australia’s largest customer-owned banks, needed a more efficient way to manage internal audit as the business grew more complex and traditional spreadsheet-based processes could no longer keep pace. Chief Internal Auditor Sara Nguyen sought an all-in-one solution to support audit planning, reporting and action tracking, and turned to Diligent for help.

Diligent implemented Audit Management and ACL Analytics through the Diligent One Platform, along with Diligent Boards for board and committee management. The result was a centralized, automated audit process with less manual work, faster reporting, better collaboration and improved transparency; TMBL now generates real-time dashboards and one-click reports, while reducing duplicate data entry and strengthening insights for leadership and stakeholders.
