Hi devsinth
Australia, NZ, the US and Canada generally offer high quality post grad degrees in sports physiotherapy so have a look at the sites available. Here is a site that lists various schools.
Schools offering Physical Therapy Degrees: The Physical Therapy Web Space (Physiotherapy)
You may get lots of recommendations from people re: favourite schools. However there are also other things to consider such as recognition of the course for where you intend to work. Another thing is to consider if the course is accredited with a national or international body that represents sports physiotherapists. this can help guarantee some quality with the course. another thing to consider is if you want to pursue a sports physiotherapy qualification (clinical focus) or an exercise science course. These obviously overlap but the latter may open doors with exercsie physiology - if you do choose this then proceed with a course at a post graduate level not undergraduate level. these courses may not be run by the physio school but by an exercise science facility.
Another thing to consider however is that as you have no working experience behind it is often wise to get some experience in an appropriate clinic before considering post graduate study. So courses won't admit you without some experience anyway.
