COVID-19 in Australia: overseas vs local transmissions
Data note: difference between 'unknown or undisclosed' and 'unknown' = some health departments have not immediately released transmission sources nor specified whether the case is still under investigation. These instances have been categorised as 'unknown or undisclosed' until they are confirmed. Where the health authority has said the transmission source is unknown or still under investigation, these cases have been categorised as 'unknown'.
