An innocuous comment on a community page's Facebook post has spurred about 40 people to carry a north Queensland grandmother with multiple sclerosis up a steep mountain so she could fulfil a childhood wish.

Janelle Boston, 55, was meant to climb Mount Tyson in Tully when she was a child in the Girl Guides but the hike was called off due to bad weather.

Before she had a chance to return, she was diagnosed with multiple sclerosis (MS) in her 20s.

The disease interferes with nerve impulses and she eventually became unable to walk more than a few steps.

In February, the Tully Community Cuppa & Chats Facebook group put up a post asking people whether there was something they had wanted to do but not got around to yet.

Among the comments about wanting to see the Bee Gees and doing Victoria's Great Ocean Road was Mrs Boston's about climbing Mount Tyson, which moved group administrator, Graham Sollitt.

"After I read that I sort of had a lump in my throat and I thought, 'My God, we have to try and do something about it,'" he said.

"I came up with the idea: why not ask Tully Rugby League if they'd be interested in doing a training run up the mountain and maybe they could take Janelle up there on a training run."

Mr Sollitt contacted the president of the Tully Tigers rugby league club, Anthony Emmi, who was keen to help.

"I was thinking, how are we going to do this?" Mr Emmi said.

"Luckily I train with [fitness trainer] Tracee Harris and I approached her to see if she wanted to help and it just so happened that Tracee also trained Janelle and it went from there."

Ms Harris arranged for a local welder to build a special chair to help carry Mrs Boston up the mountain.

About 30 of her clients joined members of the football club at the weekend to take turns carrying Mrs Boston on the five-hour return hike.

Ms Harris said while four people could carry the chair at a time, they had to use a bit of ingenuity on the more difficult sections of track.

"For a lot of it in the steeper parts we used everyone, so we'd make a file and then we'd just pass her along through everyone's hands," she said.

"Then we'd all file around and do it again and keep doing that until we got through the steep bits so no-one would slip with her on [the chair]."

Mr Emmi said it was very rewarding for all involved.

"She just smiled the whole way — couldn't get the smile off her face," he said.

"She was just grateful that so many people helped her to achieve it."

Mrs Boston's mother, Isabell Semken, said her daughter was "just beaming" as she was presented with flowers at the bottom of the mountain.

"I'm ever so grateful to all those people," she said through tears.

"Some guy piggybacked her up a certain part that was just too steep for them to carry the chair.

"People like that who are so generous deserve so much recognition."

Ms Semkin said her daughter would never have imagined a little comment on a Facebook post would have led to the weekend's events.

"She's more a shy person and no way in the world would she have expected anything like that at all," she said.

"I can say thank you but they just really won't understand what it means to me, what they have done for Janelle."

Mr Sollitt said it was a great show of community spirit.

"Those people that took her up there are just amazing," he said.

"This is what Tully's like. This is what the people in Tully are like. I've got goosebumps now. It's just amazing."
