In Australia, a Tax File Number (TFN), an Australian Business Number (ABN), and a Superannuation account are all important for individuals and businesses to have. You must at least have TFN and Superannuation ready before starting work, and you will also need ABN if you want to operate a business or work as a sole trader (some employers also prefer to pay in ABN). Here are the steps for obtaining each:

Tax File Number (TFN)

To apply for a TFN, you can visit the Australian Taxation Office (ATO) website and fill out an application form. You will need to provide proof of identity and your visa status, and you can submit the form either online or by mail.

Australian Business Number (ABN)

To apply for an ABN, you can visit the Australian Business Register (ABR) website and fill out an application form. You will need to provide information about your business, such as the type of business, the name of the business, and the names of the directors. You can submit the form either online or by mail.

Superannuation

Superannuation is a retirement savings account that is mandatory for most employees in Australia. Your employer will usually arrange for contributions to be made to your superannuation account on your behalf. There are various superannuation providers you can choose from AustralianSuper HostPlus UniSuper AMP OnePath VisionSuper SunSuper and many banks and financial institutions also manage super funds.

It's always a good idea to check with the relevant authorities to ensure that you are eligible and understand the requirements.
