JIGGI-raised Luke Harris has never let his short life expectancy stop him achieving his dreams.

Born with cystic fibrosis - a disease in which excessive mucus chronically invades the lungs and digestive tract - a single bad infection can kill him, despite the miracles of modern medicine.

Of a group of about 15 kids with the disease he knew while growing up with, the determined 33-year-old is one of only two left alive.

He was given a second chance of life 12 years ago when he was fortunate enough to receive a double lung transplant.

Over the next six years he set about achieving his life's ambition, to become a top-level fitness trainer in the NRL. He did that, becoming a trainer with the Gold Coast Titans.

But the dream came to end when, almost seven years after the initial transplant, his body rejected it.

The rejection was untreatable, and in less than five months his lung functioning dropped from 80% to 30%.

"It felt like getting hit like a freight train," Luke said.

When his professional goals became unattainable, he moved back home to the family property in Jiggi, where he set about nursing his health and planning what could be his last wish.

It was a simple goal - to build his own place to live, which for him was a houseboat.

"It was a practical choice for me," he explained, "I never had the money to buy a house or units, and I guess everyone wants to own their own home... it's one of those things you want to achieve in life."

He set about building the home on a DIY basis, scouring the internet for plans and materials, and enlisting mates to help.

After four years, the houseboat sits in the front yard of his family's Jiggi property, almost complete.

But this year Luke's health has taken a turn for the worse, and he spent four of the last six months in hospital in a perilous state.

He now has just 23% lung functioning and will not been relisted for a second transplant.

When he came back from the brink, his family recognised they needed financial help to finish the boat, license it and transport it to water.

His sister, Bobbie Andersen, launched a crowdfunding campaign on website Gofundme which has so far raised $1680 of its $10,000 target.

"I guess for Luke, his whole life he's never had a place to call his own, he's always lived under mum and dad's rood or in share houses," Mrs Andersen explained.

"Now he will have his own place."

She saidher borther had spent thousands of hours working on the project and had designed it all himself.

"It was exactly how he wanted it to be," she said.

Luke said: "It would be nice to just have it finished, and whether I enjoy that for six months or six years, you don't mind."

"As tough as it can be and it has been... I've got further than a lot of people around me did."
