South Australia has reported another 1505 COVID-19 infections amid ongoing concerns for the state's indigenous communities.
Premier Steven Marshall said six more people had died, taking the state's toll since the start of the pandemic to 117.
He said 281 people were in hospital with the coronavirus including 25 in intensive care and four on ventilators.
The new cases on Monday took the total number of active infections to 19,847 with the seven-day average falling to 1849.
Mr Marshall said a meeting of the state's COVID Response Committee had focused on providing support for Indigenous communities with Aboriginal people over-represented among the state's total virus cases.
There are currently more than 1000 positive cases among Indigenous communities with 29 people in hospital and three in ICU.
Cases on the APY lands in the state's north had stabilised but concern remained for communities on the west coast, the premier said.
"We are seeing those numbers increase but we are seeing a massive response and we are learning more and more about the most appropriate way to respond to this particularly vulnerable community," Mr Marshall said.
Vaccination rates among SA's remote areas are considered good, but more resources are being sent to assist in specific regions.
The continued fall in virus cases came as SA's school year began for some students.
From Monday, children of essential workers and others considered vulnerable returned to schools across the state.
They will be followed on Wednesday by students in reception and years 1, 7, 8 and 12 with other years learning online until February 14.
Officials are still working to roll out rapid antigen tests to schools along with air purifiers which will provided to some older sites and those with specific issues, including schools in Port Pirie where the local industry impacts on air quality.
RATs will be used as surveillance testing for teachers and other staff in pre-school settings, but will only be supplied to teachers in schools if they are deemed to be close contacts of a positive case.
In such circumstances, they will be provided with seven tests and will be allowed to keep working as long as they continue to test negative.
All teachers are required to wear masks along with students in years seven to 12.
Masks are strongly recommended for students in years 3 to 6.
