Chief public health officer Nicola Spurrier today confirmed the latest in a spate of freight industry drivers who have tested positive for COVID-19 after entering South Australia.

The latest case however, a man in his 60s, is an SA resident, prompting an immediate search for close and casual contacts.

Spurrier said the driver was thus far asymptomatic and had been transferred to the Tom’s Court COVID facility.

He was tested last night in the eastern Riverland locality of Yamba before 9pm, returning a positive test.

However, he had also been tested earlier yesterday in NSW returning a negative result, with Spurrier saying: “It does look like he’s in the very early stages of his infection.”

He had received one dose of the Pfizer vaccine, “so is not fully vaccinated and can also pass on the infection”.

The man lives in a share house in Salisbury, other occupants of which have been tested and shifted to a medi-hotel.

As yet, none has returned a positive result.

“There may be some additional people who also reside at that residence, but I just don’t have the numbers at the moment,” Spurrier told reporters this afternoon.

SA Health has identified six new exposure sites, including four Tier Three sites: a Caltex at Yamba, a BP at Blanchetown, and a Star Laundromat and Drake’s supermarket in Salisbury North.

Details will be listed on the SA Health website.

Spurrier said those four sites were listed as Tier Three sites, given the early stages of the infection.

“This person was very early in his infectious period, so we consider these casual contacts rather than close contacts,” she said.

“He’s been tested very early and because we had a negative test result from NSW we were able to have a slightly different grading for our exposure sites.”

SA administered more than 6000 tests yesterday, and has four active cases, including a woman in her 50s who today returned a positive test in hotel quarantine after earlier negative tests, which authorities believe could be an old infection.
