Migration Occupations in Demand
The Migration Occupations in Demand List (MODL) is a compilation of occupations identified by the Department of Education, Employment and Workplace Relations that are in short supply in Australia, at the time the list is drawn up.
People applying for a general skilled migration visa must pass a points test. There is no fixed Points that need to be obtained, as changes for the required pass mark according to current Australian labour market conditions. This means that a higher pass mark may be required when their are no local labour shortages in Australia.
That webpage will provide you with Contact Information and links for all the current Visa information.
