Hi there. I am an Australian physio that worked in the UK for 3.5 years. I was fortunate to be on an ancestory visa, so I had no troubles getting through immigration in the UK. However friends of mine have been given a hard time entering on a working holiday visa. One of the conditions of a working holiday visa is that you are not supposed to work in your chosen profession to enhance your career. However I believe there are exceptions to this rule, and physiotherapists are one of the exceptions (or they were in 1997). Some friends of mine got official documentation from immigration and showed it to the immigration officials (who didn't appear to know about the exceptions), others I knew pretended they were going to apply for nanny/ bar work so they wouldn't get hassled. Good-luck!!!
