South Australia has reported an increase in daily COVID-19 cases and one more death as students begin to return to the state's classrooms.
SA revealed 1723 new infections on Wednesday, up from 1266 on Tuesday.
Premier Steven Marshall said the increase was not unexpected with Tuesday's low number impacted by hot weather across the state the day before.
Mr Marshall said Wednesday's figure "isn't a number that worries us".
"But it does remind every single South Australian not to be complacent," he told reporters.
"We are past the peak, but we don't want to have a second wave."
Chief Public Health Officer Nicola Spurrier said 233 people remained in hospital with COVID-19 including 21 in intensive care where five people are on ventilators.
"It is very pleasing we are clearly on the decay of this outbreak and the wave is coming down," she said.
"But it's still very important that we're all doing as much as we possibly can to keep everybody safe."
Classes resumed on Wednesday for students in reception and in years 1,7,8 and 12 with the rest learning remotely until February 14.
