Southern Cross Austereo, owners of Seven Darwin, launched 7HD on Monday 26 November 2018. The channel is a high definition simulcast of the existing main channel, similar to most other television markets in Australia. Press release available as an image only.
An official TV schedule for Prime HD from 2007, which had the same schedule as 7HD. Back then, 7HD broadcast some of its own breakaway programming instead of being a 24 hour simulcast of Seven like it is today. Prime-HD-TV-Guide-2007-12-07.pdf
