How long is the visa issued for?

A tourist visa of subclass 651 is issued for twelve months, but you can only stay for three months after each entry. Other temporary visas are generally granted for a period appropriate to their purpose, although a time limit is used in many cases, for example, some work visas have a four-year limit and others two. Please note that permanent resident visas are valid for travel and return to Australia for only five years, although they allow you to stay in Australia forever
