# Top 30 multinational companies in Sydney

Tamtam tracks 279 multinational companies headquartered in Sydney. This list ranks the 30 largest by number of employees on LinkedIn, led by Freelancer.com, Commonwealth Bank and Worley. Their median headcount is 8,022.

These Sydney-based multinational companies are primarily large organizations with significant employee numbers. The list features a strong presence of financial services firms, including Commonwealth Bank, a leading provider of financial services in Australia, and Macquarie Group, a global financial services organization. Technology and telecommunications are also well represented, with Telstra focusing on connected solutions and Atlassian creating tools for team collaboration.

A notable characteristic is the prevalence of companies with deep roots, such as Telstra, founded in 1901, and Westpac, established in 1817. While many companies are large and well-established, there are also newer technology firms like Freelancer.com, founded in 2009, connecting users worldwide with projects.

## 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.
