The hospital site closed on Monday, with testing now being conducted at the Mount Gambier Showgrounds.
The move has been made to alleviate congestion at the hospital site, which saw vehicles lined up for hundreds of metres.
The September daily average for people getting tested at the hospital drive-through site is 186, with a total of 13,899 people tested at the site since it opened.
A Limestone Coast Local Health Network spokesperson said the new site would improve traffic flow for vehicles and provide greater space and access to testing for the community.
The hours of operation have been increased on weekends (now 8am-4pm) for community convenience.
Light vehicles including cars, utes and vans will be able to safely enter the showgrounds for testing, including walk-ins with no appointment required.
“This is a significant step forward for the South East region as we continue to take all necessary measures to help stop and spread of COVID-19 and protect our community,” the spokesperson said.
“SA Pathology will continue to provide their nursing staff at the new site and we thank them for their ongoing support and commitment to this relocation and providing this important service to the Limestone Coast and broader community.
“We continue to encourage anyone who has any symptoms, no matter how mild, to get a COVID-19 test so we can keep everyone healthy and safe.”
