@phil_ga; my 2 cents <b>below</b>:
- With my experience, what is the most suitable ANZSCO for me?
<b>- probably 221111; this is the most broad in the 2211 family
</b>2. I don't have the PICPA Certificate which was given during the oath taking and my license is currently expired, do I need to bother acquiring both?
<b>- not needed I believe but my wife submitted these as additional docs
</b>3. Academic awards ba nung undergrad are important also?
<b>- nope
</b>4. My sister is also interested in applying. She has 10years experience as an external auditor with SGV and now an Auditing firm in Singapore. External Auditor din ba pipiliin nya na ANZSCO?
<b>- external auditor</b>
Apart from the docs you have on hand, very important to get a syllabus of your major subjects in accounting. This is very IMPORTANT for your skills assessment.
