The Australian Signals Directorate (ASD) is a vital member of Australia’s national security community. We work across the full spectrum of operations required of contemporary signals intelligence and security agencies. This includes foreign intelligence, cyber security and offensive cyber operations supporting the Australian Government and Australian Defence Force (ADF).
We employ talented and dedicated people with diverse skills willing to overcome challenges in support of Australia’s interests. ASD is a world-class intelligence, covert effects, and cyber security agency because of the talented, inventive and diverse people that comprise the organisation, and the innovative technologies they employ.
ASD is a statutory agency within the Defence Portfolio with functions established by the Intelligence Services Act 2001, and its priorities are set by the National Security Committee of Cabinet. The ISA specifies that the organisation’s functions are to:
- collect foreign signals intelligence
- communicate foreign signals intelligence
- prevent and disrupt offshore cyber-enabled crime
- provide cyber security advice and assistance to Australian governments, businesses and individuals
- support military operations
- protect the specialised tools ASD uses to fulfil its functions
- cooperate with, and assist, the national security community’s performance of its functions.
A unique team
The organisation seeks to recruit and develop a curious and imaginative workforce which is not deterred by difficult challenges.
This combination of a uniquely skilled workforce, empowered by innovative technology, enabled by responsible financial management, and leveraging partner capabilities, positions the organisation to deliver trusted intelligence, cyber security expertise and offensive cyber operations for Australia’s national interest.
Intelligence analysts at ASD play a critical role in analysing intercepted signals, communications, and other intelligence sources. They examine data, apply analytical techniques and produce reports on various topics of interest to the Australian Government. These analysts often specialise in specific regions, technologies, or intelligence disciplines. Analysing foreign signals intelligence requires a systematic approach and a combination of technical expertise, analytical skills, and knowledge of intelligence methodologies.
Technical specialists at ASD are experts in areas such as communications systems and computer networks. They design, develop, and maintain the technical capabilities required for signals intelligence operations. Their expertise is crucial for intercepting and analysing electronic communications, identifying vulnerabilities in information systems, and developing advanced cyber defence capabilities.
Skilled corporate professionals enable ASD to achieve its mission. Working across ASD they perform critical functions to ensure we keep Australia secure. No matter their speciality in project management, finance, policy or HR. They use their expertise to enable the functioning of a modern intelligence agency. Opportunities are available across almost every discipline; the variety of roles are endless.
