Can I switch a subclass 400 into ongoing employment in Australia?

The subclass 400 is intended for non-ongoing work only. It is not designed to be converted into a continuing job, and using it for ongoing employment would be inconsistent with the basis on which it is granted.

If an Australian business wants to employ you on a continuing basis, a sponsored or skilled work visa is the appropriate channel rather than repeated or extended short-stay visas.

Trying to use the 400 for ongoing work, or applying repeatedly to cover a continuing role, can lead to refusal and affect future applications. Match the visa to the genuine nature of the work.
