Yarraka Bayles posted the clip of her son, Quaden, crying after he was targeted at school for his dwarfism.
"This is what bullying does," she says in the video, in which her son also says he wants to end his life.
Now a GoFundMe page has raised 30 times more than its $10,000 target.
The page was set up by US comedian Brad Williams after the video went viral to raise money to send Quaden to Disneyland.
The National Rugby League's Indigenous All Stars team have also invited Quaden to lead out the side for their match against the Maori All Stars on Saturday.
