keep Quarantine Regulations 1927 (Amendment)
Amendment to the Quarantine Regulations 1927, affecting biosecurity controls on the movement of goods, persons, plants, animals, and vessels. Registered 2014-08-22.
Quarantine regulations address genuine externalities — preventing the spread of pests and diseases that could devastate agriculture, ecosystems, and public health. Without such controls, market participants cannot internalize the costs of biosecurity breaches they cause. While implementation details matter, the core function of preventing harm to third parties is difficult to achieve through voluntary arrangements alone in a continent with significant agricultural and ecological vulnerabilities.
