Website hosted by The University of Queensland developed by the Australian Society of Parasitology, Inc. 

This website has useful background information on parasitology and individual parasites, their life cycles, host use, mode of transmission and clinical consequences. 

This would be a great resource for a medical parasitology course, or medical part of a general parasitology survey course. I could even see the descriptive information being useful in a general bio course for a definition of parasitism. The website also includes a nice section on fields of study within parasitology showing where it can overlap with courses in other disciplines.
