Were there any other factors that contributed to the cancellation of Australian Survivor?

Yes, there were other factors which contributed to the cancellation of Australian Survivor. Firstly, the show was expensive to produce. The cost of the show was estimated to be around $20 million dollars per season, which was considered too high for the ratings it was receiving. Additionally, the show was airing in a highly competitive timeslot, meaning it was up against some of the most popular shows on television. This made it difficult for the show to gain viewership, as people were likely to choose the alternative shows in the timeslot instead. Finally, there was the issue of Survivor fatigue. The show had been on air for several seasons and viewers may have become tired of its format and story. This lack of enthusiasm likely led to the show's eventual cancellation.
