Jack Gance, PhC MPS, is an Australian businessman, the self-made billionaire Co-founder and former Chairman of Chemist Warehouse, Australia's dominant discount pharmacy chain. His career is rooted in pharmacy and retail logistics. He qualified as a pharmacist in 1967 and holds an MBA.

Gance opened his first pharmacy store in Reservoir, Victoria, with his brother, Sam Gance, in 1972. He quickly recognized the immense opportunity in developing a distribution business through pharmacy and creating private label consumer brands. This focus on vertical integration and discount pricing became the foundation of his immense retail empire.

• Chemist Warehouse (Co-founder & Former Chairman): The core private asset, Australia's dominant discount pharmacy chain (over 500 stores in Australia, New Zealand, and China).
• Brand Creation: He created successful retail brands like Le Specs (sunglasses), Le Tan (suntan lotion), and Australis (cosmetics).
• Retail Strategy: His success is built on the big-box model of deep discounts on health, beauty, and pharmaceuticals.
• Family Governance: He co-founded the chain with his brother, Sam Gance, and Mario Verrocchi.

Jack Gance's strategic genius was his pivot to the discount pharmacy model. In 2000, he, along with his partners, established the Chemist Warehouse chain (and the precursor, MyChemist, in 1997). The business model, characterized by deep discounts, massive store sizes, and a high volume of sales across health, beauty, and pharmaceutical products, rapidly disrupted the traditional Australian pharmacy sector.

Under his leadership, Chemist Warehouse expanded aggressively (over 500 stores in Australia, New Zealand, and China) and gained immense financial value (through a proposed merger with Sigma Healthcare in 2024, valued in the billions). His wealth is secured by the colossal, stable, and continuous profitability of the high-volume discount pharmacy and beauty retail sector.

Jack Gance's social impact is structural, stemming from Chemist Warehouse's role in providing essential pharmaceuticals and health products at deep discounts to the Australian consumer mass market. The company is a massive employer and a major force in the national retail and pharmacy sectors.

His personal philanthropy supports various community and educational initiatives. His career is a testament to the profitability of disciplined retail logistics, discount pricing, and vertical integration in the highly competitive pharmacy sector.
