Hi
guidelines are ambiguous. I think on the form, it says to submit IELTS. Somewhere, else it says no documents. I think most of us here have agreed that IELTS is not required for the first stage. Of course, we could be wrong. Two of us on here who got through the first stage didn't do the IELTS. Both of us send a letter stating our proficiency in English. One of us was always planning to take the IELTS.
Really not that ambiguous FSW1 specifies exactly what is to be submitted. If the application is accepted by Sydney, it will be forward to the overseas office, who will write and give you 120 days to submit the requested documents, including ielts results.
