Companies in Australia

Find current and historical information about Victorian and other Australian companies.


What's your interest in a particular company? Are you a prospective employee, a supplier, or a competitor?

The aim of this guide is to help make your search easier and quicker.

Be warned - even the most thorough search may not yield as much information as you would like.

If a company is not listed on the Australian Stock Exchange (ASX), it is required to disclose very little about its operations. As at June 2022 there were over 2.6 million businesses operating in Australia and only  just over 2000 of them are listed on the ASX.

There will be even less information available about sole traders and partnerships (see the brief guide to Australian business structures).

Nevertheless, you should be able to find some basic information on any business.

Use the tabs across the top of the page to learn more about what information can be found. See the First questions tab next.

Most of the online services mentioned in this guide are available free of charge to registered users of the State Library of Victoria.
