Mrs Yorath said she first donated because she worked in the medical profession and knew how much blood was needed.
She used to donate whole blood, which can only be done every three months, but now she and Mr Yorath donate plasma once a month.
�We�ve been in the routine for the past five or six years,� she said. Mrs Yorath added that it was important to donate because there was never enough, especially of O-positive the most common type.
About 150 people are needed to donate over the Easter long weekend to boost blood supplies.
Bookings are particularly needed on Easter Monday when only 7 per cent of appointments at the Joondalup donor centre have been booked. Australian Red Cross Blood Service spokeswoman Jessica Willet said donations were essential between April 2 and 9 to ensure that hospitals had enough platelets stock.
�Platelets last only five days and are vital to the treatment of cancer patients, who continue to be the biggest users of blood and blood products in Australia,� she said.
She said finding blood donors around Easter was always a challenge because of the four-day break.
