Screen Australia have come up with this terrific link to profiles of over 50 International film festivals. You can read about the festivals and find out what (Australian) films have screened at these festivals over the last 10 years. Discover deadline and screening information, and links to each festival's official website to start entering your film.
You can sort by name, location, genre of films accepted and deadline month by clicking on the column headings below. Where the exact date is not given, the festival has yet to finalise precise deadlines.
We'd love to have the same resource for NZ films so will work on that in the future. Copy this link into your address bar and take a look...
