It's a day where all Australians celebrate our cultural diversity.
The day is also the United Nation's International Day for the Elimination of Racial Discrimination.
The continuing message for Harmony Day in 2011 is that Everyone Belongs, which means all Australians are a welcome part of our country, regardless of their background.
It's a time to reflect on where Australia has come from, recognising the traditional owners of this land.
It's also about community participation, inclusiveness and respect – celebrating the different cultures that make Australia a great place to live.
A selection of new items will be available for loan at Boroondara Libraries to celebrate Harmony Day.
