Adam Britton pleaded guilty to 60 charges, which also included four counts of accessing child abuse material.
Adam Britton, a leading zoologist who has worked on BBC and National Geographic productions, pleaded guilty to 56 charges relating to bestiality and animal cruelty.
He also admitted to four counts of accessing child abuse material.
The Northern Territory (NT) Supreme Court heard the 53-year-old filmed himself torturing the animals until almost all died, and then shared the videos online under pseudonyms.
His abuse went unnoticed for years, until a clue was found in one of his videos. Britton was arrested in April 2022 after a search of his rural Darwin property, which also uncovered child abuse material on his laptop.
Britton usually went to great lengths to avoid identifying himself or his location in his videos, but in this one a bright orange City of Darwin dog leash could be seen in the background.
God, the fucking mental fortitude it must have taken to go through those videos frame by frame. The people who do that shit should never have to work another day in their lives, just give them an income for the rest of their lives and let them go take a permanent vacation.
