After completing AMC exam & getting registered in Australia what’s next?
1)Is there any foundation/core training required before entering into residency training for IMG’s just like UK?
2)Are there any boundaries in choosing specialties for IMG’s? (Like IMGs can choose only from some specific specialties)
3)What’s the pay scale in Australia?How much tax dcotors have to pay and what about the living cost?
4)How long does it take to become a specialist in Australia?
5)Can I take my parents & spouse with me In Australia if I work there as a doctor?
