In an effort to thwart the second wave of COVID-19, South Australia will go into a full lockdown for at least six days from 12:01 am Thursday, 19 November 2020 with tight 'circuit breaker' restrictions.

A raft of closures includes schools, universities, cafes, pubs, takeaway shops and restaurants.

People will only be allowed to leave home during the six-day period for a prescribed set of reasons including to work as an emergency services worker or a worker providing essential services.
