STAFF at the Shire Blood Donor Centre are worried late-night Olympic viewing is detracting from blood donations, with bleary-eyed residents staying glued to their screens.
Blood service spokesman Lauren Dransfield said Australia needed 54,000 donations in the two weeks of the Olympics, but only about 32,000 appointments were booked in.
"The Olympics are an exciting time, but we're urging people to not forget that the need for blood never stops," she said.
"Athletes will be giving their blood, sweat and tears in London - but the rest of Australia needs your blood, and it's easy to give."
The Olympics coincides with National Blood Donor Week, when the blood service pays tribute to its army of donors.
Miranda needs at least 110 extra appointments, and Ms Dransfield urged residents to volunteer their arms.
