A TAS is required to sponsor overseas nationals for the Training visa (Subclass 407) and certain streams of the Temporary Activity visa (Subclass 408).
It is important to note that a TAS is distinct from Standard Business Sponsorship, which covers work visas like the Subclass 482. If your business already holds Standard Business Sponsorship, you still need a separate TAS approval to sponsor someone for a 407 or 408 visa. For most businesses, the TAS is sought specifically to support a 407 Training visa nomination – whether for a structured training program, skills enhancement, or professional development. The type of visa activity must match the purpose of the sponsorship.
