Australia uses a complicated and very strict rating system for its programming. It is based off of the Australian Classification Board system used for classifying films. The system uses six tiers, 7 of which are used by commercial networks.
- P: This content is purely for preschoolers. All networks are required to air at least 30 minutes of P-rated material every day. Advertisements may not be shown to interrupt P-rated progams.
- C: This content is purely for younger children. All networks are required to air at least 30 minutes of C-rated material every weekday, but only in specific periods of time (07:00 to 08:00 or 16:00 to 20:30). Advertisements are allowed, but there are limits on advertising time during C-rated programs.
- G: This content is for lots of non-inappropriate shows, but that might not interest kids. Content is very mild in impact.
- PG: Parental guidance is recommended for those under 15 years. Content is mild in impact.
- M: This content is recommended for mature audiences 15 years and over. Content is moderate in impact.[note 1]
- MA15+: Unsuitable for persons aged under 15. Content is strong in impact. Films that would get an R18+ in their original form are often edited and given an MA15+ rating.[note 2]
- AV15+: Unsuitable for persons aged under 15. A content-specific version of MA15+, was used mostly in horror films.[note 3] Since 1 December 2015, strong violence now goes under MA15+.
- ↑ M programming may air only between 19:30 and 06:00 and also between 12:00 and 15:00 during school days.
- ↑ MA15+ programming may air only between 20:30 and 06:00.
- ↑ The relationship between MA and AV is simple: Previously, any programming that gets an MA15+ with the content descriptors "Frequent Violence" or "Strong Violence" automatically got an AV15+ rating. While MA15+ content is not allowed to air before 20:30, AV15+ material must not air before 21:30. On December 1, 2015, AV15+ was completely dissolved.
