The family of a Gold Coast schoolgirl urged to commit suicide by fellow students in a Snapchat video says they were failed by the Queensland government and schools.

A video containing schoolgirls screaming vicious abuse went viral this week, and clocked up more than 70,000 views before it was removed.

A family has issued a statement saying their daughter, Amber, was the victim of the bullying, apparently by Helensvale State High School students.

They say Amber had moved to the school in 2018 to escape cyberbullying at an independent school.

The family said they sought help from authorities to no avail.
