Hi!
I'm a South African physiotherapist working in Pretoria. I would advise you to contact the North Gauteng branch of the South African Society of Physiotherapy (SASP) at [email protected]. They will be able to forward ads on posts available in Pretoria to you.
You can also consider joining the SASP if you plan to work in SA on a long term basis.
There are quite a lot af private posts available in Pretoria at the moment working in private hospitals and out patients. I'm not so sure about availability of posts in Government Hospitals.
Good luck!! South Africa has a very stimulating physiotherapy environment with lots of great courses for continueing education. You are going to love working here!!
