In Australia, the Victorian government is reportedly considering using GPS trackers to help monitor returned travellers when the state starts accepting international flights again.
The electronic monitoring devices would be used to make sure some overseas travellers were isolating at home when they returned to Australia, The Age reports.
A senior Health Department official and a government spokeswoman told the newspaper that talks were underway in both Victoria's Justice and Health departments to assess the merits of GPS tracking wristbands.
It's not expected that the trackers will replace hotel quarantine programme entirely with talks underway with arrangements being made to restart the programme.
