Tamtam tracks 57 corporate groups and holding companies headquartered in Sydney. This list ranks the 30 largest by number of employees on LinkedIn, led by Freelancer.com, Commonwealth Bank and Telstra. Their median headcount is 2,619. Half of them were founded in 1989 or later.

The corporate groups and holding companies in Sydney are concentrated in financial services, technology, retail, and professional services. Many are large, well-established organizations. Noteworthy examples include Commonwealth Bank, a major financial services provider; Telstra, focused on telecommunications and technology; Endeavour Group, which operates in retail and hospitality; and Freelancer.com, connecting users with diverse projects globally.

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 11, 2026.
