There are many factors that go into determining how much surgeons are paid, including salary packaging, hours worked, qualifications and experience.

“Surgeons working in major metropolitan areas can be among the highest earners, but there are generous salaries on offer to tempt surgeons into more rural areas too,” according to doctor recruitment agency, Medrecruit.

The country’s 3658 anaesthetists sit second in terms of high-earning occupations, banking $447,193 annually.

Internal medicine specialists (fourth, $342,457), psychiatrists (fifth, $286,146) and other medical practitioners (sixth, $259, 802) also rank highly based on average income.
