Meeting these conditions
If you do not comply with the conditions of your visa:
<i>your visa, and the visas of any accompanying secondary applicants, may be cancelled</i>
you will not be in a position to apply for another Skilled - Regional Sponsored (Provisional) visa
you will not be in a position to apply for permanent residence.

...i suggest you email your visa officer or your agent. kasi even though magka iba visa number natin it's still is the same in the sense that it falls under temporary business class visa kaya lang regional yung 475 or email lang sa DIAC, they will answer naman in 2-3 days.
my question kasi given to me by my employer hence i called DIAC was my daughter who is 4 has been staying in the philippines for the last 2-3 months now, i asked what will happen to my visa and the answer they gave me was when nag email ako sabi ng DIAC agent, the secondary can come in and out australia as long as the primary applicant has not been out of australia for more than 2-3 months. also the primary applicant must be working and must not stop working for more than 2-3 months.
if the primary applicant has not been in australia for 2-3 months then the secondary applicants' visa will be cancelled.
which is same din sa provision ng 475 visa that i copied/ pasted above.
pero best bet pa rin is to go to your agent and email DIAC personally na may change of circumstances kayo mag-asawa. mahirap kasi for secondary applicants in the sense that most documents assessed and thus given a visa approval is the main applicants like skills and the visa was granted in virtue of the primary applicant's papers.
