Rethinking the Three Rs: Growing Momentum Toward a New Gold Standard in Australian Research

Abstract

Recent years have seen increasing recognition of the scientific, economic and ethical benefits of the use of non-animal models in advancing preclinical research, giving reason to rethink the application and framework of the Three Rs. However, to benefit from the economic advantages of shifting to such alternative methods, and to realise Australia’s drug development potential, legislative reform is essential. Such reform should be responsive to international regulations that encourage the use of animal-free methods, and be coupled with a corresponding re-evaluation of current Three Rs frameworks and principles. If these supportive changes, and the recommendations from the 2023 Australian Commonwealth Scientific and Industrial Research Organisation (CSIRO) Futures Non-animal models report, are implemented concurrently — with government support paramount— then a new gold standard for scientific research in Australia could be created in which the use of non-animal models and animal-free methods is the default.
