SYDNEY: Australia will keep in place restrictions implemented to curb the spread of the coronavirus for at least four more weeks, Prime Minister Scott Morrison said on Thursday, despite signs that Canberra has been succcesful in slowing infection rates. Morrison said Australia will over the next month expand testing, improve its capacity to trace contacts of known coronavirus cases, and plan a response to any further local outbreaks. Morrison said these three steps will be finished within four weeks, and Australia will then review the restrictions that include curtailing the movements of residents, and the closures of schools, restaurants and pubs.
