South Africa or Australia

I passed the exam for studying abroad as a exchange student. At first, I really wanted to go South Africa, but I am recently in front of the alternative South Africa or Australis to study abroad. According to the reports written by students who had been in SA, SA is very very dangerous! For example, an acquaintance may be murderd and it is not unusual. Therefore, I'm afraid of my life in SA. On the other hand, Australia is much safer than SA, so I would spend a safer life than SA. However, in my opinion, studying abroad in Australia is so usual, but SA is rare, so I will be able to have experiences most people don't have. I think it will be very valuable. I am thinking which is more important, a security or a rare experience.
