Test, Trace, Isolate and Quarantine

From 23 November 2021, to coincide with South Australia reaching 80% double vaccination of people aged 16+ years, a new Test, Trace, Isolate and Quarantine (TTIQ) model is being introduced in South Australia.

Under the new TTIQ model, anyone identified as a low-risk casual contact, casual contact or a close contact of someone who is COVID-19 positive will be contacted by SA Health and provided with advice on what is required with regards to quarantining and getting tested.

The updated testing and quarantine requirements also redefine who is classified as a close and casual contact, with fully vaccinated casual contacts only isolating until they receive their first negative test result.

Whether you are a casual or close contact depends on:

  • the amount of time you were exposed
  • how close you were to the case
  • whether you and the case were wearing a mask, and
  • the setting or location of the exposure.

With this new model, fewer people will be required to quarantine. It will also enable more people to quarantine for shorted periods of time.

For example, if a vaccinated person is required to quarantine it will only be for seven days, compared to an unvaccinated person who will be required to quarantine for 14 days.
