TOTAL ANIMALS USED: 602,318

A total of 602,318 animals used for research, testing and teaching purposes were reported in 2024, that's 285,750 more than the previous year. While the majority of this increase can be attributed to the use of wild-caught fish, there was also increased use of cats and dogs, rabbits, cephalopods/crustacea, cattle, deer, goats, pigs, and sheep.

  • Animals who died or were euthanised during or after manipulations: 66,084
  • Animals who were killed for their tissues: 44,161

In 2024, an additional 139,686 animals that were bred for research, testing or teaching purposes but not used were killed. This included mice, rats, fish, guinea pigs, goats, rabbits, possums, amphibians and sheep. This is 29,121 more than the previous year.

  • Government departments: 4,294
  • Polytechnics: 25,077
  • Schools: 735

Animal use in universities increased more than 4-fold, crown research institutes almost 3-fold. Polytechnics use doubled, while commercial and school use decreased considerably.

SOURCE

Animals were sourced from the following places in 2024:

  • Farms: 195,164
