South Australia has recorded 3079 new Covid-19 cases and two deaths in the past 24 hours.
Premier Steven Marshall said it was a “massive reduction” from Monday’s 3829 new reported infections.
“It is certainly well below our seven day average,” he said.
“It gives us another very clear indication that we are at or around the peak here in South Australia.
“It gives us the optimism that the settings (restrictions) that we've put in place are reducing those numbers down.”
The state’s daily number of cases could have already peaked as the figures gradually decrease from Friday’s record high when 5679 new infections were recorded.
Yesterday, 3829 new cases and zero deaths were reported.
“We’re starting to see some very hopeful signs we’re at the peak in South Australia,” Mr Marshall said on Monday.
“Where it goes (from here) is dependant on human behaviour.”
Of Tuesday’s positive cases, 2257 were reported through PCR tests while 822 were from rapid antigen tests.
The number of hospitalisations increased by 58 to 285, but there was a reduction in patients in intensive care, now at 24. Five people are on ventilators.
While there was a larger number of patients in hospital with Covid, Mr Marshall said some of them weren't hospitalised because of their infection and has asked for a break down of those statistics.
The premier again urged anyone with symptoms to seek PCR testing, including those who had returned a negative rapid antigen test, because it was more reliable.
A $30.3 million investment was also announced on Tuxjmtzywesday to upgrade the adolescent ward and expand the emergency department at the Women’s and Children’s Hospital.
The premier revealed yesterday that 102 of the state’s 270 aged-care facilities were impacted by Covid-19 outbreaks.
An aged-care outbreaks has been defined as having at least one infectious resident or two sick staff members.
Mr Marshall said SA Health had so far given “significant” support to 11 facilities and chief public health officer Nicola Spurrier was reviewing return-to-work practices.
