Australian Visitor Visa: subclass 600.
This visa lets you visit Australia to stay for varying periods of up to three, six or twelve months at a time.
The visitor visa only allows tourism activities, no work is allowed.
This is a common visitor visa option for passport holders from many countries.
Some visa grants allow multiple entry within a 12-month period, while others are single entry only. This is often decided by the Immigration official that processes the visa grant.
