South Australia (SA) will drop the requirement for COVID-19 close contacts to isolate for seven days, but not for another week.
The change comes into effect from April 30 bringing SA in line with New South Wales, Victoria, Queensland, and the Australian Capital Territory.
It will come with new rules including a requirement for close contacts of positive cases to take five rapid antigen tests over the seven-day period.
They will also be required to wear masks when outside the home, are banned from visiting high-risk settings such as aged care centres, and must tell their employers and any schools they have contact with of their status.
