NO, you cannot expect anyone to be a sponsor to hire you.

In my experience and info from HR manager long time ago, usually employer prefer people that is already in Australia. After you arrive, then you could try to seek a job. Not easy to get a job, even more difficult to get a better job or dream job ...

Your best bet is to come here first like Neoleo said. It's really not easy to get a sponsorship but if you come here on working holiday and then spam employers with your resume or go up to heaps of businesses directly and hand them your resume

It's entirely possible for you to find a sponsor this way, although like I said it's definitely not easy or everyone will do it.
