I would recommend to process application on your own as all these agents are bunch of bullsh*t people trying to loot your hard-earned money, specially http://www.australmigrate.com/

Thats my personal experience with http://www.australmigrate.com/ that they will handover your case to such a naive person that you will feel that it would be better off do your self, Mr Frank and John are only helpful unless you have not paid them fees, the moment you paid initial fees, your application will be in dustbin and you need to remind them every other day to take your application out from dustbin and start the process.

One of my close friend engaged "Rayford" and he have similar experience of lousiness with them. So my advice to everyone here is to process yourself, it will take sometime for you to familiarize with requirements in fact it is good for being knowledgeable in term of process and requirement on other hand immigration staff either for Aus/NZ are very helpful and give response without any delay.
