Information technology infrastructure and systems, like all assets, have limited lifespans and require ongoing maintenance and management. Public sector entities are highly dependent on these systems for service delivery, and they must carefully plan for their replacement or renewal.

Many sectors continue to operate with a variety of outdated (legacy) systems, some of which support critical and public-facing services. 

A continued reliance on legacy systems can lead to operational inefficiencies, increased maintenance costs, and heightened security vulnerability. Despite these risks, entities may be hesitant to undertake large-scale modernisation projects for information and communication technology (ICT) due to their complexity, high costs, and the history of high-profile ICT system implementation issues.

Who we plan to audit

• selected public sector entities.

Other entities who may form part of this audit include:

• Department of Customer Services, Open Data and Small and Family Business.
