Hi skmbaaspirant - thanks for asking for our opinion - we have some feedback for you.
The schools you're targeting are certainly among the better ones in your geography and the good news is that they're somewhat less competitive than what many people here at GMAT Club are going for - it's a lot harder to get into many of the American and European schools, so at least you're setting yourself up with targets that have a higher chance of success than many are facing. In fact, your current GMAT score is just a notch below the average for the AGSM MBA, so that's very good. They will still be getting quite a few candidates of Indian background but since you're a permanent resident, then you may have an advantage over the NRIs. Your academics are solid and this GMAT is sufficient for one of these schools.
You should definitely take advantage of the AGSM personal consults if you can - they're holding them all over right now (eg tomorrow in Perth: http://www.asb.unsw.edu.au/events/Pages ... 5056830908
) these are very helpful and you'll have a good chance to meet the admissions people and get your questions answered. Be sure to go in there with your career goals mapped out! You want to be able to have an intelligent conversation around why you want an MBA and why you want to go to the AGSM. Also have some questions prepared in advance so that you can have a dialog with them about your bschool aspirations.
Then, you need to simply tackle those personal statements and do a good job on expressing why you need an MBA, and you could have a real chance.
If you have other questions we can help with, please feel free to ask - otherwise good luck getting started! The essays often require more effort than people realize at the outset, so moving ahead with them now will help you.
. I have a question though .. how easy/difficult is it to move from management consulting to a career in teaching ( in the field of business ) and would it be a right choice ?
