Through careful management the Australian Kangaroo Industry has developed to its current level where Australia processes millions of tonnes of high quality meat as well as a large range of leather products. Each Australian state that commercially harvests kangaroos must have in place a Federal Government approved management plan. These plans must be updated every 3 years and aerial surveys of the population are conducted every year. After assessing the total populations and trends in population numbers, a sustainable quota is set for the number of kangaroos that can be harvested for that year. Kangaroos are harvested only from primary producing properties in Australia.
