DonateLife Week is a national call to action to all Australians to show their support for organ and tissue donation.

Organ and tissue transplants give life to hundreds of Australians each year and can make the difference between seeing and being blind, mobility and never walking again, or recovering from an otherwise untreatable condition.

While most Australians support the cause, research from the Organ and Tissue Authority shows close to half of Australian families don't know if their family members are willing to become organ and tissue donors.

It is hoped that the 2013 campaign will help encourage more family discussion on the important topic. With one organ and tissue donor able to transform the lives of 10 or more people, it's a family conversation that can one day save lives.
