Our technology is based on software as a service and commercial off-the-shelf products. This means third parties can collaborate with us easily, our people can access tools and data from any location, data is securely located and accessible in the event of a natural disaster and software is regularly updated.

This year, our focus has been on managing and enhancing our technology assets to ensure they support performance. We’ll continue to make updates to our core system, START, that allow us to benefit from advances in technology and gain efficiencies.

Operating effectively in a challenging year

During the year, our systems continued to handle high loads from automatically calculated income tax assessments and customer online interactions.

We have kept improving our mobile workplace technology, which has been essential during periods where people were not able to work from the office. Everybody has a device so they can work in the office and remotely.

Cyber security continually strengthened

  • an effective security operations and incident response team
  • a mature security information and event management capability
  • evidence-based control testing through external auditors and security exercises
  • enhanced technical integration and an automation by design approach
  • a risk-based, continuous validation and increased visibility of key controls
  • the ability and agility to react to the rapidly changing security landscape
  • threat intelligence and threat hunting as a core capability, and
  • increased ability to react quickly and reduce the impact of cyber security incidents.
