@AReyes you would need at least 95 pts to have at least a chance of getting invited without going here in Australia. the issue though is how are you going to get it? Here is a rundown on where you can get your points without studying in Australia:
Age : 30 pts (if you are between 25 to 32 yrs old)
English : 20 (if you have minimum 8 bands on each module)
Overseas Skilled Employment : 5 (if you have minimum 3 yrs work experience. You can increase this to 15 pts if you have minimum of 8 yrs work experience.)
Local Skilled Employment : 0 (since you don't have work experience in Australia)
Educational Qualification : 15 (since you said: 'I graduated from a school qualified as comparable to an Australian bachelor degree')
Australian Study Requirement : 0 (not applicable to you since you did not study in Australia)
Professional Year : 0 (not applicable to you since you did not study in Australia)
Credentialled Community Language : 5 (if you pass the NAATI exam where you would need to take it in Australia. No testing center outside Australia for this one.
Study in Regional Australia : 0 (not applicable to you since you did not study in Australia)
Partner Skills : 10 (if you are single, or your Partner has competent English and has positive assessment to their nominated skill occupation.)
To sum up the above, you would only get 85 pts if you satisfy all of the above requirements within the year of completing 3 years in your company. Wait for 5 more yrs to get 95 pts as you would have 8 yrs work experience by then but there would be no assurance how many points Australian Immigration are going to invite by that time.
But if you study in a Regional Australian university, you would get 10 more pts as you can get 5 pts in Australian Study Requirement and another 5 more pts for Professional Year. This 10 pts would only happen though after 3 yrs of studying and staying in Australia. If you are lucky enough to get a local experience while doing your Professional Year, then you can get 5 more pts after 1 year of working as an Accountant. If these pts falls into place, then you would have 100 pts within 3 yrs.
**Although, if you study in a State that sponsors their own International Graduates, then you would only have to finish your 2 year course then you can already apply as a PR under that state, you still have to satisfy though the other requirements needed for that State sponsorship. Each State has their own requirements.
