'One of my earliest memories is of eating white bread sandwiches with my dad. Not Vegemite or peanut butter or devon and tomato sauce sandwiches like the other Australian kids in our working-class suburb of south-western Sydney. No, we ate oyster sandwiches with vinegar and pepper and salt. Sydney rock oysters out of a jar smashed onto bread slathered in margarine. Dad would say that we are saltwater people; we love the sea and would eat anything that came out of it. We are D'harawal Guriwal - whale people - and I wondered, who was everyone else? Were they D'harawal too?' (Introduction)
