Hi:
You can come over the WHV, but would need to leave AU and return with a new Visa sticker to come in on a student visa (you can check with DIAC if they will let you validate a student visa onshore, perhaps, but maybe not).
Skilled visas can take years to process so I don't know if you stay in AU while it is being decided.
You should really approach a migration agent as they know exactly what happens in these cases.
This post says Nov 2009, that's a few months ago so wondering what dates you really mean.
