Notwithstanding that the DIBP uses such language, visas cannot be 'extended'. It is necessary to apply for another visa.
There is no limit to the number of times subclass 600 visas can be granted, but policy is that visitors should not stay in Australia for longer the 12 months in any 18 month period. Sooner or later, subsequent visitor visa grants will have condition 8503 imposed to stop further onshore applications, or will simply be refused.
If you have been refused a visa onshore and you do not hold a substantive visa Section 48 will stop you from applying for almost all visas onshore.
If you hold a substantive visa you can apply onshore for a subclass 600 visa or a partner visa and automatically be granted a bridging visa that would have Medicare rights, and unrestricted work rights once your substantive visa expires.
All the best with whatever you decide to do.
