As an English woman who migrated to Australia in 2001 and as a teacher, I am well aware that there are certain requirements you need to fulfill in order to migrate to Australia. You usually have to score a certain number of points. The factors that are considered in attributing points are your education, your occupation, your employment history and of course your level of English language (this is where the IELTS Test comes in).
Of course visa points requirements and desired occupations do change and so I strongly suggest that you do your research and contact the Australian Department of Immigration for up-to-date information.
In the meantime, here is some information on General Skilled Migration points (correct at March 2011). The first page is blank so be sure to scroll down to the second page.
Here’s to the best IELTS score possible!
