Thank you for pointing me in a possible direction, i will consider this option. But i have some other issues so i want to move out or finding the fastest route to move there sooner. Since i don't have any solid education background, i am not scoring high enough for the points based system that Australia have to becoming a Pr. Also under the skill visa program, i am not qualified.
Fastest route is this if you thinking of going to Perth:

Entry requirements:

There are other foundation programmes but I will just quote on Perth,since the foundation programme system is generally similar to other states.
Going through the foundation programme helps you get to a 3yr degree pathway and the australian education system is a lot easier than sg.
I am not so sure if you can apply with an incomplete O levels,but I wouldn't really encourage the poly route as you have a chance of not doing well and end up wasting your time since sg education system is pretty hardcore. Know of a friend who is thinking of doing this programme as he didn't do so well for his poly.
Anyway,I am also thinking of going to Australia and might consider applying pr there later on.
Points requirement >> Got to fulfill 60 points
For Age, you get automatic 25 points. For overseas employment,you can get 10 points if you work up to 5 years in Sg but you got to provide documentation. You can get another 15 points if you do a 2yr trade-related IT diploma and take the IELTS test and get 10 points for a score of 7 or more.
Alternatively, you can try to apply for a job there and find employment over there,wait for a company to help you apply for visa.
