The Skilled Work Regional Provisional Visa subclass 491 is for skilled migrants who want work, live and study in a designated regional area of Australia. You can apply for this visa when already in Australia as a temporary resident or from overseas. If you apply for this from within Australia, you must have a Bridging A, B or C or substantive visa.
You can stay in Australia for up to five years and this visa gives you a pathway for permanent residence in Australia. Also, you must have an occupation listed on the subclass 491 skills list.
