In a recent DIBP newsletter to migration agents we found an interesting FAQ:
Can subclass 457 visa holders work part time?
“The intention of the programme is that full time work be undertaken. If advising clients who indicate that they intend to work reduced or part time hours, agents should thus be careful to ensure that they will still meet visa requirements. For example, all visa holders must be genuine in their intention to perform their nominated occupation, and must continue to perform the occupation and have no reduction in pay for less hours worked. Market salary rate and the Temporary Skilled Migration Income Threshold (TSMIT) requirements must also be met”
This is to say that regardless of number of hours worked, the visa holder must be paid an annual salary upwards from the minimum salary threshold, which means that if an agreement is for less hours, the visa holder must essentially be paid a higher hourly rate.
