The purpose of the instrument is to specify that certain former visa holders can apply for a new visa with a nil visa application charge (VAC) where their travel to and, or stay in, Australia has been affected by the COVID-19 pandemic.

Former holders of a Subclass 482 (Temporary Skill Shortage) visa (Subclass 482 visa) or Subclass 457 (Temporary Work (Skilled)) visa (Subclass 457 visa) will be able to apply for a Temporary Skill Shortage (Class GK) visa (Class GK visa) with a nil visa application charge (VAC) where they are within the circumstances specified in the instrument.

The instrument follows changes to the Migration Regulations by the Migration Amendment (2021 Measures No. 1) Regulations 2021 (the Amendment Regulations). The Amendment Regulations relevantly insert subparagraph 1240(2)(a)(iii) into Schedule 1 to the Migration Regulations, providing that a nil VAC is payable where the visa applicant is in a class of persons specified in an instrument made by the Minister for that purpose under subregulation 2.07(5). The instrument specifies a class of persons for this purpose.
