According to 2006 census data released by the Australian Bureau of Statistics, 310,089 people claimed Dutch ancestry, full or partial, and 78,927 people declared they were born in the Netherlands.

And 2-3% of the Australian Population is Afrikaans - There are Some Dutch People Born in the Dutch East Indies Too. (Now Indonesia)  

I Think It is Time to Recognise Dutch Australians as Australiaan's 

Thank You
