The Animal Welfare Act 1993 was amended on 29 July 2008. There were many changes. Most relate to increasing the powers of inspectors to take quick action to help an animal in trouble and to gather evidence for a prosecution, but they also included some changes to the rules about animal research, rodeos and the use of glue traps in rodent control.
A summary of amendments is available at http://dpipwe.tas.gov.au. Anyone who has the responsibility for an animal should understand these changes. That includes people who are directors of a company that involves animals and people who manage other staff that work with animals.
