PG rating and what applies

PG: PG or Parental guidance means that some scenes may be unsuitable for young children.

Discrimination: Discriminatory language or behaviour is unlikely to
be acceptable unless clearly disapproved of, or in an
educational or historical context, or in a particularly
dated work with no likely appeal to children.
Discrimination by a character with whom children can
readily identify is unlikely to be acceptable.

Drugs: References to illegal drugs or drug misuse must be
innocuous or carry a suitable anti-drug message.

Imitable behavior: No detail of potentially dangerous behavior which
young children are likely to copy, if that behavior is
presented as safe or fun. No glamorization of realistic
or easily accessible weapons such as knives. No focus
on anti-social behavior which young children are
likely to copy.

Language: Mild bad language only. Aggressive or very frequent
use of mild bad language may result in a work being
passed at a higher category.

Nudity:There may be nudity with no sexual context.

Sex:Sexual activity may be implied, but should be discreet
and infrequent. Mild sex references and innuendo only.

Threat: Frightening sequences or situations where characters
are in danger should not be prolonged or intense.
Fantasy settings may be a mitigating factor.

Violence: Violence will usually be mild. However there may be
moderate violence, without detail, if justified by its
context (for example, history, comedy or fantasy).
