ACMI - or the Australian Centre for the Moving Image has just created a new portal for teachers and students to learn about and find resources about film making. 

Generator has downloadable audio and video that you can use in your own video production - a stroyboard generator to help get your ideas froim paper to silver screen and loads of tutorials and expert advice from accomplished film makers from around the world.

The royalty free video and audio is great enough on it's own but if you teach media there is also a whole collection of resources that show you how to incorporate film into your classroom.
