The South African Medical Association (SAMA) will investigate allegations that medical interns have been paying for placements at preferred hospitals.
In a statement, the association said trading options were advertised on social media.
This follows a Weekend Argus report that students were willing to pay up R100 000.
"We simply cannot have a situation where intern positions are being 'sold' for whatever reason. The placement of interns is a difficult process, and many doctors are unfortunately not placed where they want to be. For those fortunate enough to have found placements, to now sell them to the highest bidders is not fair on others waiting for legitimate placements," SAMA chairperson Dr Angelique Coetzee said.
"Given the complexities and historical issues with the placement of intern doctors, the current haggling over preferred placements is out of touch with the realities of the situation. And, ultimately, this sends the message that with enough money, certain people can buy themselves the placements of their choice, a situation we cannot accept or tolerate."
She said the practice was unethical and unfair, and amounted to corruption.
Those who have further information have been urged to contact SAMA.
