RDA Northern Inland has advised the following:
The 491 skilled regional State nominated visa program is currently closed will return early in the new financial year.
We currently anticipate that to be late July / early August. Skilled migrants are encouraged to look for employment opportunities in their field in our region, in order to apply then.
