Hi Jonas,
point 1: The German Physio degree is a baseline Bachelor that is not yet internationally recognised/ accepted. The degrees I am talking about are Honours degrees. These teach e.g. autonomous practice (=direct access, diagnostics, etc.). As far as I am aware this is still not accepted in Germany. That's where I was coming from. But you are right - they could be accepted in Germany. Is it still the case, that Germany does not have nationwide regulation, but that you have to apply for registration in the federal state, e.g. Bavaria, that you want to work in? And that this registration might not be accepted in another state?

Point 2: I can understand your line of thinking now. It's excellent that you already know exactly where you want to end up, but to study Medicine takes a long long time - until you are actually in the position to work specifically in Sports Medicine. I am not sure that prolonging that process by doing a Physio degree first will aid your path or make you a better professional afterwards. I don't know what you mean by "waiting time" and having better chances at a place to study? What do you mean by having to bridge the gap. Why can you not get a place at uni after graduation?
Anyway: To me this all sounds as if you haven't made up your mind yet as to whether you want to be a Physio or a Medic. They are two very different professions and will address different areas of treatment. Both of which will be holistic in their own ways. And both will treat Sports Injuries in very different ways. And then - if you want to live in Canada, why don't you apply to study Medicine there?
I presume that you know that Orthopaedics only covers one of the three main clinical aspects of a Physio degree and in Medical, it's even less.

As to titles: I know that Germany has mixed it all up a little. In the English speaking world it looks like this:
1) Basic degree - Bachelor (Honours programme; 3 or 4 years full time)
2) Additional degree: Masters (usually 2 years if you're good ); you can only enter a Master's programme if you have a Bachelors degree;
  • Master of Physiotherapy: this is done by students of a degree relating to health who want to become Physiotherapists (e.g. if you've got a Bachelor of Sports and Exercise Science)
  • Master of Sports Physio/ Neurology/ Manual Therapy etc.: these are master programmes that are done by students with a BSc/ Physio who wish to specialise in a certain area of Physiotherapy; that's often done part time
  • Or you do only part of the papers and finish early: with those credits you might qualify you for a certificate or diploma.

3) PhD: well that's your doctorate study; length of that depends on your project and your ability to commit (e.g. if you get paid for it or not)

All of these, at least here Down Under, will mainly increase your knowledge and hopefully employability (esp. if you aspire to teach at uni), not so much wages. Most of the Physios will have done their postgrad education through high quality courses and their wages are the same.

Lastly: the information about the school subject levels comes from the websites I cited. If I were you, I would write to them and ask directly.
In NZ - difficult to say; I don't know how to compare your Abitur to NCEA. There is some explanations on the website of AUT/ Auckland University of Technology - but it's too complicated. Looks like you need to have your qualification assessed (sounds like overall at least 3 A levels and the rest at least C; but no guarantees for that). And again: your are looking at NZ$120.000 just for studying. It fascinates me that you would even consider it. I know how much the Germans here struggle just to pay for the one year they have to do to get their registration (not even considering passing their exams).

Cheers,
Fyzzio
