The Australia Institute was commissioned by independent journalist and researcher Ginger Gorman to estimate the economic costs of online harassment and cyberhate. This report is part of a wider research by Ms Gorman on cyberhate. In April 2018, a nationally representative sample of 1,557 Australians were surveyed about online harassment and cyberhate. The poll was conducted online. Questions and details of poll method and adjustments to data are provided later in this report.
