Lots of people want to know how to extend their visitor visa subclass 600 while in Australia. You cannot extend the Visitor Visa (Subclass 600). However, if you do not have a condition 8503 on your visa, then you can apply for another visitor visa while you are onshore.
If you wish to stay longer than your visa allows, then you will have to apply for another visa.
