Need advise !

Guys, i need tips for migrating to sydney for work permit. I consulted many people here in india but maximum are giving me advise to join some private colleges & do part time job. But i am not much sure about this method. I guess, this is the right platform to discuss & find out best one for me. I searched a lot on internet too but not finding much on this, there are lots of sites offering packages for the same but i want to know more about weather, people, stay, culture, etc. I got few sites like - www.Microburbs.Com.Au/ still looking further for a better information about the region. Regards !
