On 18 March 2021, the U.S. Consulate General in Perth issued a Demonstration Alert, which reads in part as follows: “Groups will undertake a series of protest actions based in Supreme Court Gardens on St Georges Terrace in the Perth CBD over the period of March 22-24, 2021. Police are expecting 500-1,000 people to be involved in the demonstrations. Other demonstration activities may occur in the CBD for the remainder of that week.”
