The grief is still fresh for his family, but today they will honour Noah by participating in the Run For a Wish fund-raising event at Aurora Stadium.

Noah was diagnosed with a brain condition, hydranencephaly, when he was only nine weeks old, and doctors told the family he would probably only live to four years of age.

In 2006 the Make-A-Wish Foundation granted Noah and his family a holiday to Queensland, where they visited four theme parks and spent some quality time together as a family.

It was just a short week of respite for the Launceston family of five, away from the pressures of finance and the physical and emotional strain of caring for Noah, but the holiday still tops their list as some of the happiest times in their lives that they will cherish forever.

Noah's mother, Lisa, said that despite the difficulties they were experiencing they didn't think that they were as deserving as others when they applied for a wish, and now they are extremely grateful for the experience they had together.

"We got the forms three or four times and threw them out thinking that there were others out there worse off than us," Mrs King said.

Mrs King said she just knew something wasn't right with Noah in the weeks leading up to his passing.

"I knew in the last 12 months that he wasn't as good as he had been over the last 10 years and I was pretty prepared that he wouldn't be around much longer," Mrs King said.

Even his brother Jalen, 12, asked his mother shortly before he passed away whether it would be all right if he spoke at his little brother's funeral.

"A week before Noah started getting sick, I said to mum that I think Noah might be going soon," Jalen said.

Jalen and Harri, 7, spoke at the funeral and told the 500 or so attendees about how special their brother was.

"Noah has been an amazing part of my life,"Jalen said.

"If it wasn't for him, I would not be the person I am today. I just know everyone is equal no matter how big or small or smart or not as intelligent.

Harri said in his eulogy: "He's good at making friends. He makes people very happy. He is really precious."

The loss the family feels is evident when they glance around the lounge room and say how quiet life is without Noah.

Father Aaron King said: "My afternoons, evenings and mornings were devoted to helping Noah, and now that he has gone I just don't know what to do with myself."

The family have made special T-shirts with Noah's picture that they will be wearing today, and will also be releasing helium balloons in memory of the happy little boy who touched so many people's lives in his 10 short years.
