I dont think theyd be allowed to apply for permanent residence i'm preety sure to live in Australia you need to be very well qualified and work for a certain amount of years and even then its a ***** to be able live here.

There seems to be a parent visa
A sponsor for applicants applying for a Parent category visa,
Contributory Parent category visa, Aged Dependent Relative
visa, Remaining Relative visa or Carer visa, must be:
aged 18 years or over; and
an Australian citizen, Australian permanent resident or an
eligible New Zealand citizen; and
a relative of the applicant or if specified in the eligibility
criteria for the relative visa class, a cohabiting partner of the
relative of the applicant; and
be settled and resident in Australia at the time the
application is lodged.
I guess anyone who wants to do that first needs to get their own General Skilled Migration visa and then apply for the parents. It's amazing how much info is clearly available on the internet, usually for most countries to know the info of visit visa's is a pain. The GSM has an online assessment test, which I think anyone with a good degree and 5-6 years of experience would pass easy. The GSM form also asks how much money you'd bring into Australia, I don't know if that's something your application would be graded on or just for their own info...
But I understand the job markets are down everywhere, you may not be able to get a job in your preferred field/industry even after your immigration.
