Once you are invited to apply for a skilled migration visa, you will need to attach evidence that you have completed a skills assessment in your chosen occupation. It is up to you to arrange and complete the relevant skills assessment for your skilled visa application. The skills assessment for Australian visas can be complex and take some time to complete. It is required that you complete the skills assessment before you submit an Expression of Interest.
On 18 April, 2017, the Australian government announced that it was abolishing the Temporary Work (Skilled) (457) visa (also known as the 457 sponsorship visa) and replacing it with the new Temporary Skill Shortage (TSS) visa. While this is still essentially an Australian work permit, the objective of these changes is to give Australian workers priority for jobs over people from overseas.
If you are planning on moving to Australia with family, there's a lot to consider. But it can be particularly challenging if one of your children is sick. Whether you will be eligible for a visa to Australia will ultimately depend on the type of visa you have applied for and the type of illness your child has.
If you are considering applying for an Australian skilled visa and are not a citizen of Canada, New Zealand, Ireland, the United Kingdom or the United States, you will need to complete an English proficiency test. The results of an English test must show that, at the very least, you have competent English language skills.
