5. Australia
Although Australia was a native country for a lot of respectable doctors, Howard Florey is the most successful one. Little known fact is that Howard Florey is the man who made penicillin available to the world. Sir Alexander Fleming discovered the substance, but it was Florey who made the discovery historically significant. He is a true example why Australia deserves to be on our 7 countries that produce the best doctors in the world list.
