Perth has gone into a five-day lockdown after a hotel quarantine security guard who contracted Covid-19 case visited a large number of locations while infected.
WA Premier Mark McGowan said how the infection was acquired “remains under investigation”.
“We are advised that he may have been a driver for one of the rideshare companies,” he said.
“The last day he worked in the hotel was Wednesday, but we are advised, and this is being carefully followed up, that he did not do any other work in the time since.”
WA Health Minister Roger Cook listed a number businesses the man visited which included Perth Convention & Exhibition Centre.
“Something did go wrong and we do need to get to the bottom of it,” Cook said.
South Australia reacted immediately to the news by shutting its border with WA without notice and forcing anyone arriving from the state (from January 26) to go into 14-day quarantine.
“These are the steps that we believe are necessary, to make sure that we can keep a level of freedom that we have in South Australia at this point,” said SA Police Commissioner Grant Stevens.
“We don’t have enough information from Western Australia at this point that enables us to make a more refined approach, so we’ve gone hard, and as quickly as we can.”
