I'm a quantity surveyor back home. Working as estimator in perth.
Yes, QS is in SOL and easy to apply PR coz IELTS requirements only 6.5 general. If you hv 8 years work experience, you'll score 15pts. 5 years 10pts, 3 years 5pts.
Construction in perth next year is shit but expect to recover in 2017 as mining will start booming again

No local experience means zero experience even you have experience in malaysia. It's different methodology.

Anyway good luck

Me no fortune teller to predict your chance of getting pr. Noted that you can surf thru DIAC website to check.
My understanding on your case is below will get highest point

Age
Your profession
Work experience exceed 8 yrs the best
Your cert from Australia
Your IELTS must band 7
State sponsors

Noted that there's heaps fresh graduate and migrants like us looking for job.

Based on your situation, I suggest you work in malaysia for 5 years then consider to work overseas or migrate.  Nowadays not just cert only but work experience is essential too.

I might be wrong. Above is just my personal opinion.

Australia is good for family with kids but not quite for single.
