This is the 12th year that the school has celebrated the event, which was this year featured on Channel Nine news.

About 300 students paraded flags for parents, community members and business people who are part of the Optus, Leaps and iTrack mentoring program.

A video of Australian musician Ben Lee's song We’re All in This Together showed footage of the entire student body singing and waving their arms in unison at an assembly.

A student from Burma's Karen community told the story of two families and their escape from the military Burmese regime.

School principal Mrs Casey used the story of one of the teachers from Arabic background to highlight the diversity in the school throughout the whole school population.

Students performed a lion dance, Cook Island dance, Hawaiian hula, Arabic bellydance, the Haka and an Indian dance.

But the ceremony's highlight was when all the dancers and singers joined in a stirring rendition of We are Australian brought many people to tears.
