47PA上写的很清楚：
Legal restrictions
Your choice of whether you apply for an offshore or onshore visa
may also be affected by migration law. For example, if you usually
live outside Australia and are visiting your child in Australia, then
the visitor visa that allowed your entry into Australia may have a
condition attached (such as an 8503 ‘No Further Stay’ condition)
that would prevent you from lodging a valid parent visa
application while you are physically in Australia.
Another example of a legal restriction is if, since your arrival in
Australia, you have been refused the grant of a visa or your visa
has been cancelled, then you may be unable to lodge another
visa application while you are physically in Australia.作者: 韵789 时间: 2015-2-2 04:50
可以的，我父母的103就是他们在这边的时候我给递交的，现在已经有排队号了。但是现在他们的签证上不能有8503条款。作者: ppkosk168 时间: 2015-2-2 10:18
