Monash is 3 years of clinical training across the board.
Basically, the traditional career progression after graduation is this:
Intern - 1 year
Resident (basically, internship without the training wheels) - for as long as it takes to get onto specialty training, 2-4 years seems common, but 5+ years is not unheard of especially in competitive specialties. This is probably going to get longer and longer now the tsunami has hit this grade. Unaccredited registrars fit here as well, except with their added level of responsibility. You could call this level career purgatory, and you wouldn't be far off the truth...
Registrar - these doctors are on their respective specialty training program. Duration variable depending on specialty and personal progress, anywhere from 3-6 years minimum.
Consultant - the fully qualified specialists (yes, GP is a specialty)
There are some deviations to this, but they're a bit more idiosyncratic and increasingly less common. There are also non-traditional career options too.
