Beccky Johns, 21, was born with a genetic disorder that eventually caused her kidneys to fail.

Beccky was on kidney dialysis for six months before undergoing a kidney transplant in 2004.

Beccky received her new kidney from her dad Paul.

It lasted four years before a second transplant was required.

This time her mum Sue came to the rescue.

The Johns family shared their story on national television this week as part of DonateLife Week 2014.

"We appeared on Sunrise, they flew us up to Sydney," Sue said.

"It was pretty exiting for the whole family - myself, Paul, Beccky and our 18-year-old daughter Tara.

"We were just talking about encouraging people to consider being an organ and tissue donor and also the importance of following that through with having that conversation with their family.

"In Australia you can still chose to be a donor but if, in that time of trauma and grief, the family decide not to, that's the ultimate decision.

"So it makes that decision easier if the families know that was what that person wanted to do.

"They can change the lives of up to 10 people as a result of that decision."

Sue said Beccky was doing well but organ donation was always something in the back of their minds.

"The drive behind this for us is just the fact that while she's really well and healthy, and we're really privileged to have been in a situation to be able to help her ourselves, if anything happens with her kidney this time then we're probably going to have to be looking at having to use a donor organ," she said.

"So we're trying to encourage that awareness of those conversations."

DonateLife Week is Australia's national awareness week to promote organ and tissue donation and is marked from February 23 to to March 2.

DonateLife Week is a key part of the federal government's national reform program to increase organ and tissue donation for transplantation and is led by the Organ and Tissue Authority.
