- A fan-voted award.
- Originally had both International and Australian categories. Last year with an international category was 1989.
- "Australian" was dropped from all award category names from 2004, although was used / not used inconsistently in the years 1990 to 2003. (i.e. used some years &/or some categories)
- In 1974 there appear to have been no awards (or just a "Special Award"?)
