Temporary work visas allow foreign nationals to travel to or remain in Australia to undertake work or other activities that would ordinarily attract remuneration. Generally speaking, activities that involve an employer-employee relationship would require a work visa.
Temporary work visas are available where the sponsoring employer is able to demonstrate that there is a lack of the required skillset in the local labour market to fulfil a necessary position within the business in Australia. There are various ways of showing this. In turn, the foreign national must be able to demonstrate that they have the skills and experience required to successfully fulfil the role.
