(Rhoda Wilson) On Saturday, 12 February 2022, Australians protested in Canberra outside Parliament House in the “Convoy to Canberra” against vaccine mandates and Covid restrictions. According to reports, Australian Capital Territory Policing admitted to the use of a Long Range Acoustic Device (“LRAD”) during the protest, however, only after Senator Malcolm Roberts and Senator Alex Antic brought up the issue in Senate estimates on 14 February.
