Case Study: National Australia Bank achieves 24/7 availability and faster releases with Jira Software

Atlassian helps NAB’s workforce with tools to power new ways of working

National Australia Bank (NAB), one of Australia’s top-four banks with 30,000+ employees, embarked on a $4 billion, multi-year digital transformation to move faster, become more resilient, and better serve customers. Rapid organic adoption of Atlassian tools across business units exposed limits in availability, scalability, and visibility—teams faced slow releases, periodic downtime, and difficulty tracking work across the enterprise as usage grew to 10,000+ active users.

NAB upgraded Jira and Confluence to Atlassian Data Center on AWS with support from a Technical Account Manager, standardized tooling, and introduced agile practices and Marketplace apps. The result: a highly available, zero‑downtime platform (no unplanned Jira outages in 12 months), monthly release cadence with releases delivered in days instead of months, faster backups (saving ~$10k/year), and measurable gains in collaboration, efficiency, and speed to market.
