Tamtam tracks 57 IT services companies headquartered in New South Wales. This list ranks the 50 largest by number of employees on LinkedIn, led by Deloitte Australia, FUJIFILM Business Innovation Australia and Planit. Their median headcount is 378. Half of them were founded in 2002 or later. The most common headquarters are Sydney (22), North Sydney (12) and Macquarie Park (3).
These New South Wales companies primarily offer IT services and consulting, with a strong focus on digital transformation, cloud solutions, and cybersecurity.

## 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 13, 2026.
