South Australia announces six-day Covid lockdown as ‘circuit breaker’ to avoid second wave

The South Australian government has announced an immediate six-day lockdown followed by a further week of tough restrictions as the state scrambles to avoid a second wave of coronavirus infections. The lockdown will take effect from midnight on Wednesday after the Parafield cluster, which started from a hotel quarantine breach, grew by two overnight to reach 22 confirmed cases. The premier, Steven Marshall, said the state needed a “circuit breaker” to allow for a contact-tracing blitz so South Australia didn’t face a crisis as Victoria experienced.
