Tasmania is open to all states and territories for the first time in nine months after dropping border restrictions with South Australia.
Arrivals from SA no longer have to quarantine, as of 12.01am on Thursday.
The only exception is people who have visited two "high-risk" locations - the Intensive English Language Institute at Adelaide's Flinders University and Woodville High School - in November.
People who've been to the venues need travel permission from Tasmania's deputy state controller.
It is the first time Tasmania has been open to all states and territories since the island shut its borders in March.
Tasmania reopened to SA in October, but was forced to close again in mid-November due to a COVID-19 outbreak in Adelaide.
All incoming travellers need to register and must be health screened and temperature checked before entering.
Tasmania's last coronavirus case was more than 110 days ago.
