There are several types of visa that you can apply to work in Australia.
Among the above, GSM is the most common one to seek a work visa in Australia. To apply GSM, you need to check if your skill is required via this
list. If your occupation is on the list, then you need to obtain a skills assessment by
contacting a relevant assessing authority directly.
You also need have 65 points to be able to make an application. The points can be changed from time to time to control the migration number in Australia, so better check
this link for updates. To find out how many points you can get, check
this page. If you do not have enough points, you still can make an application. However, you won't get the visa and you won't get the refund of the application fee as it is very clearly stated on the
Australia Government's website:
Once you have satisfied points and professional assessment, you can submit them along with your application form, and then all you need to do is wait. The visa application time can vary from 5 months to 24 months.
Alternatively, you can get a specialist agency to help you throughout the process, which can save you time and stress.
