Thursday's result left the number of cases linked to the Parafield cluster at 33 with only nine of those still considered active.
The number of people still in quarantine connected to the outbreak has also dived to 272, down from a high of almost 6000.
SA Health said 4541 tests were conducted on Wednesday, taking the total since the start of the pandemic to more than 743,000.
The results are expected to give authorities the confidence to continue to lift virus restrictions in the lead-up to Christmas.
SA last lifted some measures on Tuesday when it also dropped all border restrictions with Victoria.
It is now open to travellers from all states and territories as well as those from New Zealand.
The state is now targeting December 14 when - if all is well - it should return to the level of freedom enjoyed before the Parafield cluster emerged.
