The RSMS (Regional Sponsored Migration Scheme) has significant benefits as compared to other skilled migration pathways. However, changes are due to be introduced in March 2018 which will make eligibility for RSMS much more restricted.
To qualify, you would need to have a job offer in a regional area of Australia. The position must be in an RSMS postcode - this covers most of Australia including the whole of Western Australia, South Australia, Northern Territory, ACT, and Tasmania.
From March 2018, the selection of occupations for RSMS will be much more limited. Most applicants will need to have an occupation on the MLTSSL - at 183 occupations, this is much shorter than the RSMSOL which has 673 occupations. Additional occupations may be available for regional positions, but at this stage it is not clear how many extra occupations will be available.
