  • Have a specific purpose such as maintenance, installation, or expert consultation

Many engineers, consultants, and technical experts use the 400 Australian visa for short assignments such as machinery installation, training programs, or urgent on-site troubleshooting.

Subclass 400 Visa Rules and Restrictions in Australia

  • You must not study or undertake unrelated work.
  • You must maintain valid health insurance for your entire stay.
  • The visa is generally single-entry, and re-entry requires a new application.
  • You must leave Australia before the visa expires, unless applying offshore for another visa.
  • You cannot switch to another work visa, like the 482, while inside Australia.

 

Who Can Apply for the Subclass 400 Temporary Work Visa?

  • You have highly specialized skills or knowledge not easily available in Australia.
  • You have a job offer or invitation from an Australian company or organization.
  • You can demonstrate sufficient funds to support yourself during your stay.
  • You meet health and character requirements.

Can You Extend or Renew the Australian Visa 400?

Extensions for the Australian visa 400 are not typically granted. However, if your project is incomplete or you have a valid reason, you may apply for a new 400 visa from outside Australia. Your extension request must include strong supporting evidence from your employer justifying the need for a longer stay.

 

Transitioning from a 400 Visa to 482 Visa

In some cases, employers may wish to retain a skilled worker beyond the 400 visa period. While you cannot directly transition from a 400 visa to 482 visa inside Australia, you can apply for a Subclass 482 Temporary Skill Shortage visa after returning home.

This process allows businesses to bring in the same expert for longer-term projects under standard 482 visa sponsorship requirements.

  • Clearly demonstrate how your role requires specialized skills not available locally.
  • Ensure your employer provides a detailed invitation letter.
  • Apply well in advance to accommodate processing time.
  • Maintain adequate health coverage during your stay.
  • Follow the exact job description stated in your visa approval to avoid breaches.
