South Australia's government announced considerable adjustments to isolation measures for contacts of Covid-19 cases on Monday, ahead of the reopening of the border. According to sources, South Australian Premier Steven Marshall declared that beginning November 23, fully vaccinated South Australians who are regarded a close contact of a COVID-19 case will only be required to quarantine for seven days.

Casual contacts who have been fully vaccinated will only be needed to self-isolate until they have tested negative for Covid-19. Anyone in South Australia who is regarded a contact of a positive case is currently required to quarantine for 14 days, regardless of vaccination status. "The test, trace, isolate, and quarantine needs will be greatly reduced," Marshall told reporters.

"We have had to adopt a really heavy-handed approach in the past, to be honest, since a single case might trigger a cluster that would shut down our state." On November 23, South Australia will open its borders to fully vaccinated passengers from the Australian Capital Territory (ACT), New South Wales, and Victoria, with the goal of reaching 80% of over-16s fully vaccinated. It will be the first time since August that visitors from those regions, which have been under Covid-19 lockdowns in recent months and account for more than half of Australia's population, will be permitted to enter SA without having to wait 14 days to be quarantined.
