Please note: to register a private or public company that's unlimited (where the liability of shareholders is unlimited) you need to apply by using a company registration form.

A company is a type of business structure. When you set up a company, you create a legal entity that's separate from you.

At the Australian Government Business Registration Service website you can register the following types of companies using an online form:

  • proprietary limited companies (also known as private companies) – the most common company structure used by small businesses
  • public companies limited by shares or guarantee
  • public companies with no liability
  • special purpose companies – not for profit, home unit/body corporate or superannuation trustee.

The online form will also:

  • tell you what information you need to complete your registration
  • allow you to save your progress and come back later
  • give you other helpful information related to companies
  • let you make other business registrations you may need.
