Hi Maurya!

Doctors make far more on average in the US than in the UK or Australia. This is because both UK and Austraila have free public health systems. This provides a cap on doctor's salaries. So, there is no definite number for the salaries, but on an average the doctors in US usually earns about $189,000 and in UK, it is around 103,000 pounds = $153,056 USA Currency. For Austrailia it is ,  $165,750 (USA currency). Also, it depends on the specialization the doctors have, it could weigh less or more depending on the knowledge.

Thankyou!
