http://www.salaryexplorer.com/salary-survey.php?loc=196&loctype=1&job=13&jobtype=2 has figures for 50+ specializations. From the comparison, you can get a feel where each specialization stands in the pack.

https://www.salary.sg/2007/doctors-pay/ is fairly realistic, with 900+ comments up to 2018

eg: Radiologist is one of the highest paid specializations. I guess it’s 300-400k for a fully qualified radiologist.

Informally, my intern colleague said “20-30k” is a typical layman estimate.

SG median salaries shows GP at 12k/M

— why bother?

In the Sgp culture , doctors are by far the most recognizable and respected profession. We all have first hand experience dealing with doctors. We have good estimates about how much they have to study in school, how hard they work, and how much they earn. As such, this profession (actually this group of individuals) are a poster boy profession.
