"Her organs went to six different recipients," Lauri said.

"That's got to make you feel something good came out of it."

Kelly Evans, better known as Digga, died of an asthma attack in late 2005. She left behind twin daughters, Tahlay and Jayde Bird, who are now 10 and being raised by Lauri.

Digga recorded her wish to be an organ donor on her driver's licence but never discussed it with her family. Lauri had no hesitation in giving her permission for the donation.

"It was what she wanted," she said.

"Who am I to say no?"

But not all families agree to donate their loved ones organs even if they have expressed their wishes on a driver's licence or register.

In an effort to increase the number of organ donors, the Federal Government today launched the Australian Organ and Tissue Donation and Transplantation Authority.

It is the first time Australia has had a national body to co-ordinate organ transplants and its first project is to get people to discuss organ donation with their families.

Greg Davis, of Valentine, received his new kidney just three weeks ago after two years on dialysis and 12 years suffering from kidney disease.

The 40-year-old said the transplant would enable him to do things most people took for granted such as take a holiday, exercise and eat properly.

Although grateful to receive the call telling him he had a kidney, Mr Davis said it was "bittersweet" because he realised someone had died to give him that gift.

Lauri Evans said her granddaughters already told her they want to be organ donors like their mother.

"My mum did a wonderful thing," Tahlay Bird said. "She saved six people's lives by being an organ donor. I am so proud of her."
