Yes, you can! There used to be a rule preventing people who lived in the UK between 1980 and 1996 from giving blood in Australia, but it was changed on 25 July 2022.
The rule was related to the fatal variant Creutzfeldt-Jakob disease (vCJD, the human form of the bovine condition sometimes known as ‘mad cow disease’). Read more about the UK donation rule change.
However, if you’ve received a blood transfusion in the UK between 1980 and now, you won’t be able to give blood.
Please note that vCJD is different to classical Creutzfeldt-Jakob disease.
