(Bloomberg) -- Australia will halve the number of citizens who can return home at any one time to relieve pressure on its system of quarantining arrivals, Prime Minister Scott Morrison said Friday.

Morrison told reporters the quarantine system would also be reviewed.

More than 70,000 Australian citizens and permanent residents have undertaken 14-days of mandatory isolation at government-leased hotels since the crisis began and the policy has helped contain the spread of the virus. But the system is creaking, particularly as flights are rerouted due to an outbreak in Melbourne, placing pressure on other parts of the country.
