I heard on the radio today that the Army is out on the streets in Sydney enforcing the lockdown due to protests about it over the weekend.
Yep. The army will be knocking on doors to check that people that are supposed to be at home are at home. The head of the police there was asked if the soldiers are vaccinated. He said no but they are wearing the same masks as the police (The surgical masks that are not designed to stop viruses).
