The Australian Red Cross Blood Service has echoed the words of cancer victim Holly Butcher, who penned a letter published after her death that encouraged people to regularly give blood.
In the heartfelt message posted on Ms Butcher's Facebook page, the 27-year-old said donations had prolonged her life and she asked people to "do a good deed for humanity [and myself] and start regularly donating blood".
"I feel like it is something that is so overlooked considering every donation can save three lives!" she wrote.
Ms Butcher, who News Corp reported had died of Ewing's sarcoma, wrote that blood donations allowed her to have an extra year of life.
"A year I will be forever grateful that I got to spend here on Earth with my family, friends and dog. A year I had some of the greatest times of my life," she wrote.
