The Australian System Safety Virtual Conference (ASSC) is organised by the Australian Safety Critical Systems Association (aSCSa), a Special Interest Group of the Australian Computer Society. ​

The theme for the 2021 virtual conference is “Complex Systems: Can We Keep It Safe Anymore?”. With systems becoming more integrated, networked, and complex – incorporating new/emerging technologies, automation, autonomy, and artificial intelligence – ‘system of systems’ challenges such as emergent behaviour, cybersecurity, and human factors become more prominent.

The 2021 ASSC would like to examine and share the latest thinking on the state of the art and its fitness for purpose. We invite research papers and project experience to present and engage.

​Topics of Interest

The conference invites original and unpublished works that advance the state-of-the-art in safety and security considerations for the development and operation of safety and security critical systems. We are particularly interested in cross-industry and cross-pollenisation, and looking for papers in:

Delegates have the option of submitting two types of papers:

  1. Refereed Papers by the conference program committee
  2. Industry Presentations/Papers (not subject to peer review)

Both types of papers are published on the conference website, and if sufficient papers are submitted, published in the Journal of Safety and Reliability Society.


Important Dates


Conference registration fees (except as noted) includes attendance at all technical sessions on Wednesday, Thursday and Friday, special Thursday evening social event, and the conference proceedings. *Note that there will be a small social event in Brisbane, Melbourne and Canberra for local conference delegates.

Presenter’s Rate FREE

All fees as listed above are in AUS Dollars and GST inclusive. For questions about registration, contact George Nikandros at


Prof. Chris Johnson

Prof. Chris Johnson Pro-Vice-Chancellor (Engineering and Physical Sciences), Queen’s University Belfast

Chris Johnson leads the Faculty for Engineering and Physical Sciences at Queen’s University in Belfast. Prior to that he was Head of Computing Science in the University of Glasgow for six years. His research supports the engineering of complex systems; ranging from accident and incident investigation through to contingency planning and risk assessment for European critical infrastructures. The technical focus extends from mathematical reasoning to applied engineering. He has held fellowships from NASA and the US Air Force and has 250 peer-reviewed publications. He worked with the Ministry of Housing, Communities and Local Government on dynamic integrated risk management techniques to identify, measure and mitigate the social and economic impact that fire and other emergencies can be expected to have on individuals, communities, commerce, industry and the environment. He worked with the US (NIST) data to model different evacuation methods for large public buildings; following the 9/11 and 7/7 attacks. He has advised a range of other UK government departments including BEIS, DfT, DCMS, FCO and the Home Office. In 2020, he is expert witness to the Grenfell Tower inquiry focussing on communications and data issues in the response to the disaster.
