The national cybersecurity agency will get a new leader after its head Abigail Bradshaw was appointed the Australian Signals Directorate’s next director-general.

Ms Bradshaw will take the reins of the organisation from September 6, replacing outgoing director-general Rachel Noble.

The new director-general has served as the deputy of the Australian Signals Directorate since March 2020 and has also been the head of the Australian Cyber Security Centre, where she has spearheaded responses to major cyber incidents.

Prime Minister Anthony Albanese congratulated Ms Bradshaw on the appointment.

“At a time of increasingly complex geostrategic challenges, Ms Bradshaw’s expertise in both cyber and national security matters will be critically important in leading the Australian Signals Directorate to continue protecting our nation,” he said.

Ms Bradshaw said: “ASD’s focus will remain steadfast on continuing our proud history of support to the Australian Defence Force, collecting foreign signals intelligence, conducting cyber offensive operations and protecting Australians from cyber threats.

“I look forward to leading the incredible, mission-focused team at ASD as we continue to advance Australia’s national interests.”

As well as her four years as deputy director-general, Ms Bradshaw has served in various roles in the navy, the Department of Home Affairs and the Department of Immigration.

Defence Minister Richard Marles said Ms Bradshaw was well equipped to lead the directorate in efforts against global cyber threats.

“As Head of ASD’s Australian Cyber Security Centre, Ms Bradshaw has strengthened relationships with cyber security leaders and private network owners in Australia and internationally, including our Five Eyes partners,” he said.
