There are a lot of options in similar fields. You could explore massage or athletic therapy. I'm not sure how things are regulated where you are. In Canada physios and massage therapists are regulated by a college and athletic therapy is not. This can make a difference in wages, whether insurance will cover fees, and that sort of thing.
I know a number of people who have schooled in two out of the three, with a kinesiology undergrad, as well. So committing to the schooling in another direction may slow you for a time with applying to physio, however, if you work hard and get good grades, it can also improve your chances with a physio school.
You could also spend a lot of time volunteering in a physio clinic, but that won't advance you as much as concrete schooling will.
