Cosec Partners celebrated its 50th anniversary on 11 February 2026 with an evening event in Adelaide attended by clients, partners, and team members, marking five decades of operation.
The milestone follows the company’s recent rebrand to Cosec Partners. The business’s focuses on supporting local clients through company secretarial services, corporate compliance, entity establishment, and ongoing governance support. ABN Australia, part of the same corporate group, specialises in assisting international businesses expanding into or operating in Australia, providing company and branch establishment, resident director, accounting, tax compliance, and regulatory advisory services. Together, the two entities reflect a complementary service model built over 50 years.
The celebration was held at the Weber Grill Academy Adelaide, 144 Fullarton Road, Rose Park, South Australia, from 5:30 PM to 8:30 PM. The venue, widely recognised for its barbecue expertise, hosted a structured evening featuring dinner and an interactive barbecue experience. Guests also enjoyed views across the Adelaide city skyline from the academy’s balcony.
Managing Director Aaron Garry addressed attendees, outlining the origins and evolution of the business and formally introducing team members. David Garry also spoke, recounting how the company first began and highlighting its expansion over the decades.
Several prizes were awarded throughout the evening, including barbecue sets. The major prize, a barbecue grill, was awarded to one of the company’s earliest and longest-standing clients.
The event provided a valuable opportunity to reconnect in person with long-standing clients and partners while celebrating a significant milestone in the organisation’s history.
