Gretel Lees Packer, AM, is an Australian billionaire investor and philanthropist. Her wealth is rooted in the family's media and casino empire, founded by her grandfather Sir Frank Packer and greatly expanded by her father, the media mogul Kerry Packer (d. 2005). She is the sister of fellow billionaire James Packer.

Gretel's career is defined by generational stewardship and her profound commitment to philanthropy, particularly in the arts and environmental science. Following her father's death and a massive A$1.2 billion settlement in 2015 with her brother James (related to the division of assets), she inherited substantial investments, including in Crown Resorts, securing her financial independence.

Gretel Packer's primary focus is her extensive philanthropic portfolio and her governance role in the family's assets. She is the Chair of the Packer Family Foundation and the Advisory Board of Crown Resorts Foundation. Her strategic vision centers on using the immense wealth of the Packer and Crown enterprises to fund community activities aligned with the arts, education, and environmental science.

Her structural contribution is massive: the Packer Family Foundation and Crown Resorts Foundation pledged A$200 million over ten years for the National Philanthropic Foundation. She is the Vice-President of the Board of Trustees of the Art Gallery of New South Wales and a Founding Patron of the Taronga Zoo Conservation Science Initiative. Her commitment to the arts was highlighted when the Roslyn Packer Theatre was renamed to honor her mother's contributions. Her wealth is secured by the colossal, long-term returns generated by her family's diversified industrial and casino assets.

Gretel Packer's social impact is massive and structural, tied to her role as a major cultural and environmental patron in Australia. Her foundations fund crucial research and community programs. Her environmental focus (Taronga Zoo Conservation Science Initiative) and her support for the Sydney Theatre Company provide structural contributions to national culture and science.

Her career provides a unique example of an heir transitioning to a powerful role as a philanthropic leader, focusing on measurable impact and community development.

Gretel Packer maintains the elegant, composed style of an Australian heiress and cultural patron. Her attire is consistently high-quality and fashionable, reflecting her status in the arts community. Her aesthetic is one of stability and profound social responsibility.

Residing in Sydney, New South Wales, her luxury is the immense security and financial reward derived from her multi-billion dollar fortune. Her life is dedicated to the stewardship of her family's media legacy and her profound commitment to philanthropy and the arts.
