When was the Bachelor degree of Occupational Therapy introduced in Australia?
The government board wasn't really helpful, but I found the answer:


  For a few years there had been a combined Physiotherapy/ Occupational
  Therapy Degree course at The University of Queensland. In 1955 the
  Occupational Therapy three year Diploma course was introduced.
