The only B schools in Australia with international reputation and good placement are : AGSM and MBS, with AGSM slightly ahead of MBS due to its higher selectivity of students, Sydney location, better placement, smaller class-size and better ranking in FT and Forbes.
If you have 5+ years of quality experience and if you have a
PR of AUS, then these two schools are very good options to consider.
My comments are based upon my recent discussions with Indian students at these two schools.
thanks
