# 37 leading Banking companies in Australia

Tamtam tracks 37 Banking companies headquartered in Australia. This list ranks all of them by number of employees on LinkedIn, led by ANZ, NAB and Westpac. Their median headcount is 651. Half of them were founded in 1957 or later. The most common headquarters are Sydney (8), Melbourne (7) and Adelaide (2).

These Australian banking companies are predominantly large and well-established institutions, with several founded in the 19th century. They offer a wide array of financial services to individuals, businesses, and corporations. Notable examples include ANZ, a banking institution with over 180 years of history, and NAB, dedicated to serving customers and supporting communities. Westpac, founded in 1817, provides financial services globally, while Bendigo Bank focuses on community-centric banking solutions.

## 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 12, 2026.
