Businesses based either in Australia or overseas are allowed to sponsor workers for a temporary visa for certain occupations lasting up to 4 years only under the Temporary Work (Skilled) or 457. Employees are required to be paid at the current market rate.
The Employer Nomination Scheme permanent visa’s criteria are broadly similar to the 457 visa except that it requires the nominating employer to be operating in Australia and for the employee to demonstrate a higher level of skill than for a 457 visa.
The RSMS visa requires that the job offer come from a regional area and is subject to cancellation should the employee leave employment within 2 years of obtaining the visa. Additionally, the employment has to be approved by a Regional Certifying Body however the skill level criteria are lower than those for an ENS visa.
