The Australian Bloodstock Code of Practice published on 9 May 2007 by the Australian Racing Board sets out principles that apply to sales of thoroughbred race horses helping to ensure that sales continue to achieve high standards of integrity and transparency. A breach of this Code of Practice in New South Wales may result in a penalty being imposed by Racing NSW (or by another other Principal Racing Authority if the breach occurs in another State or Territory) under the Australian Rules of Racing including warning-off. Refer AR 209, AR 7(s) and AR 175(v).
Also, find a link to the website of Thoroughbred Breeders Australia which houses the Australian Thoroughbred Sales Code of Conduct that sets out principles agreed to by the signatories to that Code of Conduct. It also contains a process whereby complaints can be made to a Complaints Advisory Panel and an enforcement regime that can result in disciplinary action being taken by a signatory to that Code of Conduct.
