A Queensland man has been left heartbroken after his little brother was admitted to hospital for attempting to take his own life due to bullying.

Murray Benton, from Gympie, Queensland, posted the distressing photo of his 12-year-old brother in a hospital bed wearing a neck brace on Facebook. The boy was admitted to Lady Cilento Children's Hospital in Brisbane at the end of February.

The distressed brother of the boy wrote he had to watch him being strapped to a hospital bed and that it left him and his family shattered.

Mr Benton wrote it's the second time his brother has attempted to kill himself after being bullied.

He added the intention behind the post was to express his "honest disgust" and to "spread some much-needed awareness of bullying in our schools".

"For months now, this little guy has been bullied at school, he has been pushed around, been called names, been involved in both group and one on one fights, been made the laughing stock in front of his peers and the list goes on," he wrote.

"Due to this constant harassment and negative engagement this has not only affected him greatly but has also had a negative impact on our family unit and how we operate on a daily basis."

Mr Benton said the school needed to do more to protect their students - particularly against what he calls "repetitive bullying".

He claims one child was given a three-day suspension for bullying his brother but is now free to return to school to "repeat the same behaviour again".

"After speaking to other parents within our Gympie community and hearing how many kids are in the same boat with our schools I am fully aware that he is not the only one," he wrote.

"This in itself is disgusting."

Many have wished the 12-year-old boy well and expressed concern over his treatment at school.
