The thirteenth and final season of the Australian police drama Blue Heelers premiered on the Seven Network on 1 April 2006 and aired on Saturday nights at 8:30 pm. The 11-episode season concluded 4 June 2006, due to its cancellation by the Seven Network as a result of its sharp decline in ratings. When, in late 2005, the time came to renew Blue Heelers, Seven commissioned eleven further episodes to be produced, but its future after this was still undecided. In January 2006, Seven officially announced that they had cancelled Blue Heelers, but would air a final shortened season of only 11 episodes in mid-2006—the 11 episodes which had been filmed in late 2005, before Blue Heelers had been cancelled. This season focuses primarily on the show's main protagonist, Senior Sergeant Tom Croydon, his failing health and his personal troubles. John Wood, who portrays Croydon, is the only actor to appear in every episode of Blue Heelers and is, indisputably, the pillar of the show. The final episode of the thirteenth season aired as a 2-hour, movie-length tribute starting with an introduction from John Wood, and concluding with a compilation of Blue Heelers moments from over its 13-season run. For this thirteenth season, Blue Heelers was moved from its primetime Wednesday-night timeslot to the lower rating Saturday-night timeslot, which saw it come up against The Bill, a British police drama which has become quite popular in Australia. Ratings for this season, partially due to the series' move to its lower-rating timeslot, were relatively low; ratings were around the 1.2 million viewer mark, increasing to 1.5 million for the finale. Blue Heelers failed to even make it into the top 20 programmes at any time during its thirteenth season.
