Many students seek to remain in Australia after completion of their course in Australia, or change visas during their studies.
Examples of visas students often apply for after being in Australia for some time include:
Graduate Temporary Subclass 485 visas
General Skilled Migration
Employer-sponsored (457 or TSS visa)
Partner Visas
Working Holiday Visas
Occupational Trainee Visas
Further student visas
These visas may not have work rights as beneficial as the original visa held by the employee. Unless visa status is checked regularly, these issues will not be picked up by employers.
A good example of this is when a student is working casually for Employer A whilst on a student visa. If they then transition onto an employer-sponsored 457 or TSS visa with a different employer (Employer B), they will no longer be able to work for Employer A as this would be a breach of visa conditions.
