How long does it take to be doctor?

Year 0
This is when you are completing high school. You need to register for and sit the Undergraduate Medicine and Health Sciences Admission Test (UMAT). The university you are applying to will have an interview process, so be sure to check with them directly regarding the details.
Years 1 and 2
If you are successful in gaining a position, most universities will give you entry into a two year accelerated degree called something such as medical science or biomedical science, with a provisional entry into the medical degree upon successful completion of your undergraduate degree.
Years 3 to 6
4 year medical degree – this is the university component of the medical training. This degree may be known as a Doctor of Medicine or a Bachelor of Medicine/Bachelor of Surgery. Universities tend to teach the degree with a “problem based learning” approach. There are also practical placements which are mainly in hospitals.
Please note that instead of the 2+4 pathway described above, some undergraduate medical degrees are 5-6 years.
Years 7 and 8
Intern year and residency year – junior doctors generally spend two years rotating through different departments in the public hospital setting. It is not unusual to move to a different town or city for a few months at a time during these years. Please also note that some people do more than one residency year.
Years 9 to 11/12/13 (and beyond in some cases)
Vocational training – The time comes when you need to choose which specialty training program/s you would like to apply for. That is, do you want to become an eye surgeon, dermatologist, anaesthetist etc. For example, it takes 5 years to complete a fellowship of the Australian and New Zealand College of Anaesthetists to become an anaesthetist. It takes 5 years to complete a fellowship with The Royal Australian and New Zealand College of Ophthalmologists. It takes 3-4 years to become a general practitioner. It takes 4 years to complete the fellowship of The Australasian College of Dermatologists. If you choose to sub-specialize within a particular area, then the vocational training can take around 8 years.
It is worth noting that positions for vocational training in some specialties are hotly contested. We have heard rumours that in Queensland in 2015 there will be 7 places available for surgical training with the Royal Australasian College of Surgeons, and that 80 junior doctors were interviewed for these places. If you are not successful in gaining entry into the vocational training program of your choice, you would need to re-apply the following year.
