The Bachelor of Physiotherapy is a very popular degree at Newcastle, which is obviously reflected in the ATAR cut-off.
I would say your best option would be to focus on your studies for now, and when it comes time to make course choices, look at the B. Exercise & Sports Science like you mentioned and look to transfer after a year. However, even then you would need to do extremely well in your first year so that you could use your GPA plus ATAR to be considered.
I'd say best thing for you at the moment would be to focus on your studies, as they will ultimately determine your choices for next year.
If you're still stressing out about your options, you can give the Program Officer an email and she might be able to clear things up for you (Warning: They can be very busy at certain periods of the year, so you may have to be patient waiting for a response).
