Please note that the 489 visa is closed to new applications and has been replaced by the 491 visa.
The Skilled Regional (Provisional) Subclass 489 visa is a 4-year provisional visa which requires holders to live and work in a regional area to obtain permanent residence.
To qualify, you would need be sponsored by either a relative living in a designated area or a State or Territory Government.
The applicable occupations list if sponsored by a relative is the same as the list for the Skilled Independent visa.
The state sponsored 489 occupations list can be seen here.
If you are sponsored by a relative, you will need to live for 2 years and work full time for 12 months in a regional or low population growth area to qualify for permanent residence through the Skilled Regional Subclass 887 visa.
The applicants can either be in Australia or overseas to lodge this visa.
