@green_apple - based on my understanding, professional year is a job preparedness program sa australia. so in short,, parang mag ojt ka sa australia. may mga courses sila na qualified for this (ex. it or engr).. if you have this, meron kang additional points sa immig points system..
you may refer to this link for the details:

ung isang nabanggit nmn na NAATI accreditation, is for community language (ex. Tagalog), you will need to sit an exam to certify that your have a skill in the level of interpretation/translation (ex. Tagalog-english and vice-versa). if you have this meron ka ding additional 5 points..
google NAATI for their website and where take the test in your location..
hope this helps..
