For your film to satisfy G (General) classification, the language and themes should be VERY mild in impact. Meaning there is nothing in the theme, language, nudity, sex, violence or other matters that the ratings board thinks would offend parents whose younger children view the picture. The film content should be suitable for all ages including young children.
For PG-rated classification, the content is not recommended for viewing by people under the age of 15 without parental guidance. The overall impact of your film should be no higher than mild. However, there may be some infrequent scenes that children might find confusing or upsetting and would require the guidance of parents, teachers or guardians.
If you are still unsure what classification your film should be, visit the Australian Classification website at www.classification.gov.au which has more information on the rating guidelines.
Keep in mind that Films with any graphic violence, profanity, or mature content will not be accepted.
