In the early 1980s, a high number of HIV transmissions were caused by infected blood products. As a consequence of this, since 1983 a guideline issued by the federal State Medical Board of Registration has banned blood donations from high-risk groups, including gay men. Since 1985, mandatory testing off all donations has been required, and the rate of HIV transmission by blood products has dropped to practically zero. Although the exclusionary guidelines have been retained under the Law of Transfusion 1994, there has been no research performed to justify this policy. The present report shows that there was little thought behind the retention of this policy. The assumption that blood safety is reliant upon excluding gay people is inherently false, as it is impossible to exclude gay people from donating. Therefore the polities of exclusion do not work in practise, although it is a fact that current blood supplies are HIV free, proving that there is another combination of factors ensuring the safety of the blood supply.
