2004 in Australian television

In 2004, Australian television saw several significant developments. On January 1, Tasmanian Digital Television launched in Hobart, while WIN TEN began broadcasting in South Australia as a supplementary service. In February, the Nine Network introduced an afternoon news program at 4:30 pm to compete with Seven's existing service, which had been established due to the Iraq War. Deal or No Deal premiered on February 1 and became a major success, leading into Seven's evening news.

In March, the special "The Secret Life of Us" aired, though focus remained on ongoing shows. April marked the move of Futurama from Seven to Network Ten. Wheel of Fortune was revamped in April but faced low ratings, leading to its cancellation later that year. May saw the premiere of The Block on Nine, which gained popularity and continued through 2004.

On July 25, Stingers ended its six-season run on Nine. By December, networks replaced movie openers with classification boards. Nine secured the ratings season for the fourth consecutive year, winning 38 out of 40 weeks, while Network Ten led Seven nationally for the first time. Ten introduced a watermark in December, initially on the bottom left of screens.

Notable shows included The Block and the conclusion of Stingers, alongside programming shifts like Futurama's network switch. These events highlighted dynamic changes in Australian television, reflecting both audience preferences and strategic network moves.
