Yes, though I do not think that they are the SA contact tracers.
Dr Louise Flood, Director of SA Health’s Communicable Disease Control Branch, indicated on 1 April that the SA Contact tracing team was to be expanded with 150 contact tracers, and another 150 on standby if required.
All states had various levels of contact tracers as there are ongoing diseases communicable diseases like measles etc to be managed and for which contact tracers are used. Covid 19 though has seen that all expanded. So new staff to be trained in all states.
