Summary: The rise of disinformation presents a growing and material risk to the operation of Australia’s democracy. A response that is specific to the Australian information environment and co-designed with Australian government decision-makers will enable an agile, practical and evidence-based response to emerging threats in this space. In 2017, organised social media manipulation campaigns took place in 28 countries. In 2019, organised social media manipulation campaigns took place in 70 countries. Russia has historically spent around $1.2b on pro-Kremlin media activities to drive disinformation. China has historically deployed between 300,000 and 2,000,000 people on information warfare and psychological operations. “Millions have already been exposed to false information about the [coronavirus]... it is undeniable that the damage [of misinformation] is real.“ (The Guardian) The UTS Behavioural Data Science Team within the UTS Data Science Institute draws on extensive experience in the analysis of, and response to, viral disinformation content. Focus areas include the spread and nature of disinformation in the Australian information environment, the presentation and visualisation of disinformation flows, and appropriate mitigation measures in both policy and defence contexts.
