Heloise Pratt (née Pratt) is an Australian billionaire heiress and businesswoman. Her wealth stems from her inheritance in the massive Visy Industries (packaging, paper, and recycling) empire, founded by her grandfather, Leon Pratt, and greatly expanded by her late father, Richard Pratt. She is the sister of fellow billionaires Anthony Pratt and Fiona Geminder.

Heloise's career is defined by her move into investment and private equity. She and her former husband, billionaire investor Alex Waislitz, co-established Thorney Investment Group (Thorney), a large, diversified private investment house.

Heloise Pratt's strategic genius was her role in founding Thorney Investment Group (in 1991, managed by her ex-husband) which became a platform for extensive investments in sectors like biotechnology, energy, fintech, and listed shares. While her brother Anthony runs the core Visy manufacturing business, Heloise's focus is entirely on strategic investment and high-yield asset management.

Her wealth is secured by her stake in the private Visy Asia-Pacific packaging business and her large investment portfolio in Thorney. Her career has been marked by acrimonious legal disputes with her former husband, Alex Waislitz, over the division of their immense joint financial holdings, a saga that has highlighted the complexities of managing dynastic wealth and corporate governance in Australia.

• Visy Industries (Family Shareholder): Her inherited stake in the massive private packaging and recycling conglomerate.
• Thorney Investment Group (Co-founder & Investor): A large, diversified private investment house focusing on biotech, energy, and fintech (co-established with ex-husband Alex Waislitz).
• Philanthropic Focus: She oversees the Pratt Foundation's $1 billion fund, which distributes around $20 million annually to health, education, and the arts.
• Controversy: Her wealth has been tied up in a high-profile legal dispute over the division of her investment assets.

Heloise Pratt's social impact is massive and structural, stemming from her role in managing the Pratt Foundation's A$20 million annual distribution. Her philanthropy supports a broad range of community activities and charities aligned to the arts, education, women's leadership, and Indigenous community programs within Australia.

Her structural contribution is tied to the financial stability of the Visy empire and her role as a major patron of the arts and social causes.

Heloise Pratt maintains the elegant, composed style of an Australian heiress and investor. Her attire is consistently high-quality and fashionable, reflecting her status in the arts and society. Her aesthetic is one of refinement and confident self-direction.

Residing in Melbourne, Australia, 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 legacy, her investment strategy, and her profound commitment to philanthropy.
