The nine year old student who refused to stand to during the national anthem, has sparked outrage from politicians and media figures.

Year 4 student Harper Neilson says the National Anthem does not recognise indigenous Australians, and erases 50,000 years of Aboriginal history.

State opposition MP Jarrod Bleijie referred to her as a "brat," while Pauline Hanson says she would give the girl a kick up the backside.
