South Australia has recorded another five deaths of people with COVID-19, with two in the past day.
Three others have only just been reported.
The five further deaths take the state's total since the start of the pandemic to 74 and the number since the November 23 border opening to 70.
"We have seen deaths occur within aged care facilities and I think we have been quite clear around [the fact] that there are a number of individuals who were already in the palliation pathway who contracted COVID as a result of being in a facility where there are active cases," the state's Deputy Chief Public Health Officer Dr Emily Kirkpatrick said.
SA Premier Steven Marshall confirmed the state had recorded 1,869 cases — the lowest daily cases tally this year.
"We're absolutely delighted with that figure," Mr Marshall said.
"We are tracking extraordinarily well in South Australia."
The seven day case average is 2,630.
There has been a reduction in the number of people in hospital with the virus, down to 287.
The number of people in ICU however has increased to 32, but only five people are on ventilators.
A total of 63 of the 287 people in hospital were deemed to be "incidental" COVID cases, meaning they were in hospital with COVID, rather than because of it.
"That's climbed to well over 20 per cent now," he said.
The Premier also encouraged people to seize the opportunity to get PCR tests, given the low demand and the sometimes unreliable results of Rapid Antigen Tests.
"There is virtually no line-up at any of our PCR testing stations at the moment … the turnaround time is extraordinarily low at getting that result," he said.
"Many close-contacts may chose to now have the PCR test rather than going to collect their two free SA Health-provided Rapid Antigen Tests."
He said the state had access to 1.1 million RATs and there were another 22 million on order.
He said there was no shortage in the health sector.
Despite that he said there would be no changes made to the use of the at-home tests when schools return.
After two-thirds of teachers voted to strike over current return-to-school plans, he said negotiations were ongoing with the teacher's union.
"We're on strong ground, we've listened to the experts since day one … we're in respectful negotiations," he said.
"We'll go through the reasons why Rapid Antigen Tests can give a false sense of security, unless they're carried out in a controlled way.
"We don't support the strike and we'll be doing everything we can to avert it."
Business support plan in the works, home care expanded
He said the details of another financial package of support and stimulus for businesses affected by the current restrictions was in the works and would likely be announced by Saturday.
More detailed information on the "pathway out of this particular wave" was also in the works.
The government today announced additional $2.3 million for Wellbeing SA to make calls to vulnerable community members living with COVID in their homes.
Deputy Chief Public Health Officer Emily Kirkpatrick said the expansion of the home COVID telephone monitoring program, with calls at least once a day, would be especially helpful to those most in need.
"This program was specifically targeted around individuals who are more vulnerable in the community [and] may not have a mobile telephone number," Dr Kirkpatrick said.
"Not only are they providing clinical advice but also support around logistics, food and other support they may need whilst in isolation.
"This involves SMSs being sent out to individuals, asking them to complete an initial survey and working through their health advice."
Dr Kirkpatrick said there would be support for people who do not have internet access, are elderly and may require the assistance of translators.
"If someone doesn't have access to the internet, we have a system in place whereby if they've not responded back within 24 hours to their SMS, we then phone call them."
Dr Kirkpatrick said about 0.7 per cent of people with the disease were being admitted to hospital.
