As the state urgently battles to contain the virus, South Australians have turned out in droves to get screened for COVID-19.
As a northern suburb cluster sparks second wave concerns, queues have extended for kilometres at clinics across the state.
On Tuesday, after the nearby Hungry Jack’s was considered a COVID-19 exposure spot, cars started lining up at the Port Adelaide testing site as early as 4 a.m.
Some in the line said they were waiting for Monday for more than five hours before being turned away.
They now come prepared with snacks and games to pass the time, not to be dissuaded.
Hundreds of cars lined the streets by 8am when the testing station opened.
Around the clock, health officials are working frantically to process what is expected to be a record number of tests.
Wait times have exploded to 11 hours at Parafield, the cluster’s epicentre, and the drive-through clinic at Victoria Park has also been flooded.
