What options you think I should consider?
		
		
	 
I generally would not recommend doing an undergraduate degree before med 
if you don’t have to (unless it was under a guaranteed entry scheme like unis such as USyd and UQ offer). You should aim for undergrad med if that’s what you have your heart set on for two main reasons:
   1. Time - as 
@Eagle Mum has already noted, postgrad med takes a minimum of 7 years compared to undergrad which takes a minimum of 5 years. To put that into perspective, once you have finished a postgrad med your fellow undergrad friends could already be junior registrars (assuming internship and residency take one year each) and on their way to specialising.
   2. Risk - once you have completed your undergraduate degree, there is no guarantee that you will be accepted into a med programme leaving you with a degree you have no use for (unless you change your career pathway). This is a major factor that you will have to account for. 
So, I would advise you aim for an undergraduate med programme and if you are unsuccessful then try for postgrad med.
