first, 6K AUD for your agent will be a burden for you.. you could buy a 2nd hand car for that here.. you can do the processing by yourself but you have to do some research on how to.. but this thread can help you alot in doin so..
Second, certificate IV in nursing would lead you to Division 2 nurse.. Div 2 nurse works under the supervision of div 1 nurse... before it was just a 1-yr course, but recently they've changed it to 1 & a half yr... some uni here offers that course for 10K AUD before for an international student (tution fee for the whole yr).. with the current changes im not sure how much it cost.. this course doesnt have complicated requirements like BP.. This is a TAFE course.. so one doesnt even need a nursing registration from overseas (not sure tho)..
BP cost approx 10K for just 3 months.. then ul be registered as div1 nurse..
so why go for cert IV rather than BP? :):confused:
