A security guard who was in charge of monitoring returned travellers quarantining at an Adelaide hotel has been dismissed for breaching COVID-19 protocols.

The guard was caught not wearing a mask while monitoring those in quarantine.

SA’s Chief Public Health Officer Dr Nicola Spurrier said that while the incident did not put anybody at immediate risk, it was still against the rules.

“It was just a warning: ‘Okay, you’ve been told you have to wear a mask. You’re not wearing it, you’re out of here,” Dr Spurrier told the ABC this morning.

“The police have a very, very strong presence and they are overseeing the security guards and that was how it was picked up.”

The news comes as the spotlight turns on to Melbourne’s quarantine hotels, which are said to have been responsible for a large number of new coronavirus cases in Victoria.

There are currently 415 confirmed, active cases of COVID-19 in Victoria, with an official inquiry into the handling of the state’s quarantine hotels being launched.
