Cyber security

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

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

​On 6 August 2020, the Australian Government released Australia’s Cyber Security Strategy 2020.

The Australian Cyber Security Strategy 2020 will invest $1.67 billion over 10 years to achieve our vision of creating a more secure online world for Australians, their businesses and the essential services upon which we all depend. It will be delivered through:

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

While this Strategy is an Australian Government initiative, we recognise the essential role of state, territory, local governments, businesses, academia, international partners and the broader community in strengthening Australia’s cyber security. Every part of government, business and the community has a role to play in implementing the Cyber Security Strategy 2020.

The Australian Cyber Security Strategy 2020 replaces Australia’s 2016 Cyber Security Strategy.

For cyber security assistance and further information on how to protect yourself online, see cyber.gov.au.


The Australian Cyber Security Strategy 2020 was informed by extensive consultation. Between September 2019 and February 2020 we met with more than 1,400 people from across the country in face-to-face consultations, including workshops, roundtables and bilateral meetings.

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

The Minister for Home Affairs also established an Industry Advisory Panel to provide strategic advice to support the development of the Australian Cyber Security Strategy 2020. The Industry Advisory Panel has released its final report available at 2020 Cyber Security Strategy Industry Advisory Panel.

Protecting Critical Infrastructure and Systems of National Significance 

As outlined in Australia’s Cyber Security Strategy 2020, the Australian Government is committed to protecting the essential services all Australians rely on by uplifting the security and resilience of critical infrastructure.

Consultation on the reforms outlined in the Protecting Critical Infrastructure and Systems of National Significance Consultation Paper closed at 5pm (AEST) Wednesday, 16 September 2020. For further information see:​ Protecting Critical Infrastructure and Systems of National Significance​​
