Tattarang

Tattarang is the private investment group of Australian business leaders Andrew and Nicola Forrest. The firm operates with a philosophy of using capital as a force for good, integrating environmental, social, and governance (ESG) factors into its investment decisions. Tattarang focuses on generational businesses and assets deemed critical for national resilience and long-term prosperity, investing across a diverse range of sectors and asset classes, including real assets, public, and private markets.

The firm was founded in 2001 by Andrew Forrest, initially operating as Minderoo Group. In May 2020, it underwent a rebranding to Tattarang, a name chosen to honor a stallion owned by Andrew Forrest's mother at the family's Minderoo Station during the 1950s. This name symbolizes qualities of trust, care, and spirited determination. The rebranding served to clearly differentiate the commercial investment activities from the Forrests' philanthropic arm, the Minderoo Foundation, while maintaining a commitment to purpose-driven investment.

Tattarang's extensive portfolio is managed through several key business divisions, including Fiveight (property development and operations), Harvest Road (agri-food), Squadron Energy (renewable energy), Tenmile (health technology), Wyloo Metals (mining and battery metals), and Z1Z (consumer, lifestyle, and sport). Notable investments include iconic Australian brands such as R.M. Williams, Akubra, and Camilla. The firm also holds significant stakes in major enterprises like Fortescue (a leading iron ore producer transitioning to green energy), Austal (shipbuilding), Australian Agricultural Company (cattle and beef production), and Bega Group (food and beverages). Through its Tenmile venture platform, Tattarang actively supports innovative healthcare solutions.

The firm is led by Chief Executive Officer John Hartman, who was appointed in October 2022, having previously served as Chief Investment Officer since 2012. As of January 2026, Tattarang's team comprises 26 members, including 7 partners and 4 principals. The leadership team is dedicated to driving investment strategies that not only deliver strong commercial returns over a long-term horizon but also achieve positive environmental and social outcomes, aligning with the firm's core values.
