The love child of late packaging magnate Richard Pratt claims her older half-brother, billionaire Visy boss Anthony Pratt, witnessed displays of love and affection between father and daughter, according to new legal documents in a multi-billion dollar inheritance claim.

Paula Hitchcock, in an amended statement of claim, alleges Australia’s fourth-richest man, Anthony Pratt, and his siblings, Heloise Pratt and Fiona Geminder, were aware of their half-sister’s position in the Pratt family and regularly saw their father’s “bonds of love and affection” for her.
