AN additional 6000 donors are required over the next two weeks to prevent a shortage of blood products for patients across the nation.
More than 25,000 donations are needed each week in order to help cancer patients, road crash victims, unborn babies, women in childbirth and people undergoing emergency surgery.
Australian Red Cross Blood Service spokesman Shaun Inguanzo encouraged people to roll up their sleeves.
"One in three of us will need donated blood in our lifetime and the only way to ensure that it will be there when we need it is to give it," he said.
"Australia relies on around 500,000 donors so we know that there are many more people who could possibly give blood but currently do not.
"We are urging people who are aged between 16 and 70, feel fit and healthy and who want to help save lives to make an appointment to give blood."
