South Australia reports no new Covid cases and urges people to avoid lockdown loopholes

South Australia didn’t report any additional cases of coronavirus as the state entered a strict six-day lockdown in an attempt to halt an Adelaide cluster that authorities worry could become a second wave. The so-called Parafield cluster remained at 22 on Thursday with three people in hospital in a stable condition. There are 17 additional suspected cases. The state’s chief health officer, Prof Nicola Spurrier, revealed the news at a testy press conference where the police commissioner clashed with reporters who questioned whether security guards at quarantine hotels should be allowed to work multiple jobs.
