As always, countries that have high intakes of immigrates, only do so on a needs basis. If there is not a need then jobs that are advertised should not have an option of sponsorship if there are locals that can apply. It is not a responsibility considered by the Australian government, to give as many overseas nurses that request a job a visa and a job, it is their responsibility to make sure there is a skilled workforce however and that locals with Australian education and are citizens or permanent residents have first rights to a job that they are qualified for against any other applicants with no bias or discrimination.
The demand for nurses in Australia, but particularly, Victoria, Queensland and reported in other states and territories, have been flooded in the past with overseas applicants so the need for overseas educated nurses is low, even without the cutbacks, as Australian universities and Tafes have increased their student intakes in both the Bachelor of Nursing and Enrolled nursing courses by 50 to 100%.
And the government is now clamping down/ reviewing the whole system/ has made statements.... on those who do not advertise or consider, local applications first and one of the most abused visa is the 457 that requires sponsorship by an employer as they are supposed to have advertised and waited a period of time and cannot fill the position with a local.....which often is not the case and will now be scrutinised.
If a nurse applicant from overseas, has skills and experience that is in short supply locally by proof of advertising and lack of local applicants with the experience and skills, then of course the overseas applicant would be welcomed, if found suitable and given sponsorship by the employer for the visa.
