Cyber security

Cyber security is important for Australia's national security, innovation, and prosperity.

​​​​​​​​​​​​​​​​​​​Australia’s Cyber Security Strategy 2020

On 6 August 2020, Australia’s Cyber Security Strategy 2020 was released.

Through the Strategy, $1.67 billion has been invested over 10 years to achieve a more secure online world for Australians, their businesses and the essential services upon which we all depend. It will be delivered through:

  • Actions by governments to strengthen the protection of Australians, businesses and critical infrastructure from the most sophisticated threats.
  • Actions by businesses to secure their products and services and protect their customers from known cyber vulnerabilities.
  • Actions by the community to practice secure online behaviours and make informed purchasing decisions.

While this Strategy is an Australian Government initiative, state, territory and local governments, as well as businesses, academia, international partners and the broader community play an essential role in strengthening Australia’s cyber security.

The Strategy replaces Australia’s 2016 Cyber Security Strategy.

The Strategy was informed by extensive consultation. Between September 2019 and February 2020, more than 1,400 people from across the country were consulted, including through workshops, roundtables and bilateral meetings.

215 written submissions in response to a call for views were received. 156 of these submissions were public and have been published.

The Industry Advisory Panel was also established to provide strategic advice to support the development of the Strategy.

Protecting Critical Infrastructure and Systems of National Significance 

As outlined in the Strategy, the Australian Government is committed to protecting the essential services all Australians rely on by uplifting the security and resilience of critical infrastructure.
