I think this is misleading as the medicos salary is computed as base pay and medics hardly ever (if ever!) get bonuses. It would be much more meaningful to publish annual income with bonuses included, and to give the 50th rather than 75th percentile.

Also, why only specify specialist surgeons and what exactly do the mean by "general physicians"? It is a rather vague term which can be variously interpreted as either any internal medicine specialist (e.g. cardiologist, neurologist, endocrinologist etc.), internal medicine specialists specializing in general internal medicine (unlikely since there are only about 30+ in Singapore and they're not very well paid, and I find it hard to believe they are paid more than anethesiologists, radiologists and other procedurists), GPs, or something else altogether.
Danny,

Interns get about $48,000 a year. As for surgeons, it takes a rather long time to actually become one. , since there's one year internship, typically 2 years residency as an RMO, then 6 years of full time training assuming your offspring passes all his/her exams the first time round, which statistically speaking is unlikely. Note that more popular surgical specialties like cardiothoracic surgery and ophthalmology would usually take 4 years of residency/unaccredited registrar work just to become a registrar.
