Around 100 other baggage handlers are now being investigated, with a large number expected to be forced to self-isolate for 14 days.
Qantas said it is working to minimise any disruptions to customers who are flying in and out of Adelaide, although passenger numbers are significantly reduced due to government travel restrictions.
“Seven flights to and from Adelaide are affected,” a Qantas spokesperson told Travel Weekly.
“This includes one Sydney flight that was on its way to Adelaide which will return to Sydney and passengers will be provided with accommodation and put on alternative services [on Wednesday].”
Qantas said it was working closely with SA Health to conduct a thorough trace for each of the confirmed cases.
“In addition to enhanced cleaning measures introduced since the coronavirus outbreak at airports and on aircraft, we are conducting extensive cleaning of common areas used by these employees in Adelaide.”
South Australia’s chief public health officer, Nicola Spurrier, said on Tuesday that she recommended for anyone who travelled through the airport over the past few days to wipe their luggage.
SA Health says it is investigating a cluster of coronavirus cases among Qantas baggage handlers at the Adelaide Airport, as the state records 32 new cases.
Six baggage handlers have tested positive to COVID-19.
Chief public health officer Nicola Spurrier said about 100 other people work in the immediate area of the airport, and a "significant number" of people would be required to self-quarantine.
Dr Spurrier recommended people who have travelled through the airport in the past 24 hours to give their bags a wipe-over
