There are several visa options that allow businesses to sponsor overseas workers to work in Australia. They are:
Temporary Skilled Shortage (TSS) Sponsorship (482 visas)
The 457 visa has been abolished as of 18 March 2018 and replaced by the Temporary Skills Shortage (TSS) subclass 482 visa. This visa allows businesses based either in Australia or overseas to sponsor workers for a temporary visa lasting up to 4 years. Only certain occupations are eligible for TSS visas, and employees must be paid at the market rate.
Employer Nomination Scheme (ENS) The Employer Nomination Scheme is a permanent visa, and requires the nominating employer to be operating in Australia. The employee needs to show a higher level of skill than for a TSS visa, but otherwise the criteria are broadly similar to the TSS visa.
Regional Sponsored Skilled Migration Scheme (RSMS)
The RSMS visa requires a job offer in a regional area. The position needs to be approved by a Regional Certifying Body, but otherwise the skill level criteria are lower than for an ENS visa. The resulting RSMS visa is a permanent visa, but is subject to cancellation if the employee leaves employment within 2 years of obtaining the visa.
Temporary Work (Short Stay Specialist) Subclass 400 Visas For people undertaking highly specialised work or they are working in Australia's interest.
Temporary Activity Subclass 408 Visas For people coming to Australia as an invited participant, on exchange with an Australian business, for sporting activities, as a religious worker, a Domestic worker, to work in the entertainment industry, for research activities with an Australian educational institution, or as part of a special program
Training Subclass 407 Visas For people working as an occupational trainee or as part of a professional development program.
