After struggling for nearly a decade, Sam passed away last week after falling ill. "Sam passed away on Friday morning at Hornsby Hospital, not far from where he grew up, surrounded by 20 of those he most loved in the world", she wrote. He mentioned to his mother and the doctors that he had eaten a slug earlier. His last words to his mother Katie were: 'I love you'.
He endured numerous medical complications over the years, including seizures.
He died Friday, surrounded by his family and friends, Australian journalist Lisa Wilkinson reported.
"Sam was a true battler and hero to his younger brother Joshua and sister Melanie".
In their obituary, Ballard's family described him as "a true battler" whose hard final years had been brightened by "an army of friends and family".
"I try and make it matey and fun - we will crack a beer, when Katie goes out of the room, he reaches for it, he gets his lips out and sometimes we put a little bit of beer on his lips".
A funeral service will be held for Sam on Thursday, according to a post on Galvin's facebook page.
He contracted eosinophilic meningo-encephalitis, which some people recover from.
'That's bad, my son shared his room with him at the Ryde rehabilitation centre.
In this special report Lisa Wilkinson talks to Sam Ballard's awesome friends and family.
The Independent wrote, that Katie Ballard "said she did not blame the friends who dared her son at the 2010 party". That's how it happened'.
In the following days Mr Ballard fell ill and was told by doctors he had been infected with rat lungworm.
The worm is generally found in rodents but slugs and snails can get infected from eating their droppings.
The turning point in Ballard's life came when a friend noticed a slug crawling across the garden, and dared him to eat it.
'Let go of the guilt and try to find some peace themselves.
Rest in peace Sam.. Hopefully your friends will keep visiting your mum and family in the coming years.
The friends of the young man, who have always done everything for that rugby remains a part of his life, then made a pot to help the family Ballard.
Before the accident, Mr Ballard's mother described how she saw her son as "invincible".
"Sam is doing really well".
She added: "It's devastated, changed his life forever, changed my life forever".
It was 2010 and it was a night that would change the 19-year-old's life, and the lives of everybody around him, forever.
