Hahaha I had a friend who actually transferred from speech pathology to occupational therapy.
Anyways, you can always transfer to any degree you want - literally (just maintain a credit average; or even better a gpa of 5.5 if you can)!
If you want to stick within health sciences though, you can do speech pathology, physiotherapy, orthoptics, radiography and exercise and sports science ^_^! http://sydney.edu.au/health-sciences/disciplines/index.shtml
