Primetime is officially, in terms of ratings figure designations, from 6:00 p.m. until midnight, however the peak audiences are between 6:00 and 10:30 p.m. Primetime programming is advertised as starting from 7:30 p.m., with more family-friendly programs airing during this time, until classification restrictions allow for racier content from 8:30 p.m. There is a small audience drop off at 9:30 p.m., and a significant audience drop off after 10:30 p.m., with not much promotion given to programmes airing after this time. Late local news programmes only air on one of the three networks. As a result, the late fringe occurs from 10:30 p.m. to around 12:30 a.m., depending on the programme which precedes it.
