These Australian companies are predominantly involved in chemical manufacturing, mining, and construction materials. They include large established enterprises with significant workforces. The list features companies like Orica, a provider of mining and infrastructure solutions, and Boral, Australia's largest vertically integrated construction materials company. DuluxGroup manufactures and markets products for living and working spaces.
A notable pattern among these companies is their long-standing presence, with many founded in the late 19th or early 20th century. Headquarters are distributed across various major Australian cities, including Perth, Melbourne, and Brisbane, indicating a broad geographical spread rather than a single urban cluster. Wesfarmers Chemicals, Energy & Fertilisers operates chemical, energy, and fertiliser businesses.

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.
