The state of western australia can nominate you for a visa under the skilled nominated visa (subclass 190).
There are two lists of occupations eligible for this visa that can be found here: https://migration.wa.gov.au/…/skille…/occupation%20lists
These lists are for the general skilled nominated visa and graduate skilled nominated visa streams.
To qualify for the graduate stream you must have completed a cert three or higher education course, but there are many more occupations in the graduate stream.
Also, higher level qualifications such as a PhD get preference when the state nominates for the graduate stream.
So read the list, find a course or get job hunting as nominations for this visa will be opening soon!
