For a great list of film competitions see this link
Other great Teacher Networks are:
Drama Queensland (DQ)
There is also a very detailed website from one of our Victorian members. Although certain aspects focus on the Victorian VCE, much of the resources on this site by Brett Lamb are invaluable for media teachers.
QUEENSLAND UNIVERSITY OF TECHNOLOGY (QUT)
Did you know teachers can now apply to borrow books from the QUT library? And we have a GREAT film, television and media section!
The restriction is that you need to come and get the books (and return them) yourself. So this will mostly be of interest to Brisbane teachers.
