Bosco Harris was just three years old when he was diagnosed with a rare form of leukaemia.

He needed more than 30 blood transfusions during his treatment, which ultimately saved his life and helped get him to remission.

Bosco is among one in three Aussies who need blood in their lifetime and as our population ages and more treatments are discovered, that number is expected to grow by 100 percent over the next 10 years.

So with only one in 30 people giving blood each year, Bosco and his mum are encouraging more of us to donate and potentially save up to three lives.

Dr Andrew catches up with Bosco in tonight's feature story.
