South Australia’s coronavirus cluster has grown after two new cases were announced on Thursday morning.
Premier Steven Marshall said the new cases were a brother and sister who attended the Tenafeate Creek winery at Yattalunga on Sunday, which has become a superspreader event.
The parents of the siblings, who are aged in their 20s, were also at the winery at the exposure time and have so far tested negative.
At least five other cases are linked to the winery.
The state’s outbreak has now grown to 14 cases, with more exposure sites expected.
SA’s second superspreader site is The Greek on Halifax restaurant in the city where a number of infected people dined last Saturday.
Authorities have identified 206 people who attended the venues at the exposure times and are now moving them to medi-hotels.
Marshall said he was grateful the state went into lockdown on Tuesday and thanked residents for abiding by the stay-at-home orders.
“I’m extraordinarily hopeful that we can stop the spread of this disease over the seven-day lockdown period,” he said.
“If people don’t need to leave home, don’t do it at the moment.”
More than 17,000 people came forward for tests in SA on Wednesday – a record figure for the state.
The premier apologised for long delays at testing sites and understood that some people were frustrated at having to wait many hours.
But he said authorities were working hard to increase capacity.
The number of SA exposure sites has also grown to more than 70 with about 4000 people in quarantine.
SA’s virus cluster is linked to an 81-year-old man who recently arrived in Australia from Argentina and was quarantined in Sydney before travelling to Adelaide, where he tested positive.
Genomic testing has confirmed the man became infected while in Sydney, not while in Argentina.
Under the week-long lockdown, which started on Tuesday evening, South Australians are only be allowed out for five reasons – to provide essential care, to seek medical assistance, to buy essential food and other goods, for essential work, or to exercise.
They must also wear masks when outside their homes.
Schools have closed along with most retail outlets and all construction work has ceased.
