HI,
doubts are OK, they keep you focussed.
If you want a job that does not require constant updating and lifelong professional development - don't chose anything scientific, whether that's medical or science technology. That's not a burden, that's what makes the job interesting.
I feel sorry that your clinical educators are unable to highlight to you the significance of physio work in a hospital. Deciding whether patients are safe to discharge is of huge importance, early mobilisation prevents a lot of secondary complications and if you mess up your intervention in Trauma and Orthopaedics, your patients will suffer for the rest of their lives. These roles each have a high degree of specialisation in themselves. Ask your Clin Educator why you fail to see that. However, you do not have to like hospital work - it's extremely draining with a never ending workload that needs to be squeezed into small amounts of time, includes weekend duties and a high emotional involvement. On the other side - it's the best for team work, peer support, supervision and free of charge training opportunities.
At some stage you will have to decide whether you want your physio career to be in prevention, primary (e.h. hospital or private practice), secondary (Rehab) or tertiary health (Community, private practice). And the specialisation comes after that decision - pretty much straight away. And then, after a few years, you might like to chose a different path of specialisation. And you can - another beauty of being a Physio.
You can apply for registration in Australia, but will have to pay a substantial amount of money for the application and the exams. NZ has a 4 year degree, so they require 12 months of clinical experience before you can apply.
The training is tough, but you're just about there - keep on going, you'll be fine.
