Hi Elena,
I'm a South African physiotherapist who left the country about 10 years ago now. I was based in Cape Town at a private practice inside a hospital. Work wise, it is a very interesting place to work and gain experience. I cannot tell you the salaries at the moment since I've not worked there in so long. However, to start your process, you can look at the website of the Health Professions Council of South Africa (HCPSA) in order to find out how to get on their professionals list. Then I can put you directly in touch with some of my friends who are working there. I hope this helps you. Might be a bit late as I see you posted back in August.
You can always send me a private message if you want to have a chat.
Kind regards.
