Meh even if he was a troll, I’ll assume the OP is just ill-informed and it is a legitimate question. Plus, are we here to ridicule or help?
It is a MASTERS Program, therefore it is post grad, hence the reason u aint finding it in Undergrad Course Guides. That means, you need to have completed a degree etc before hand plus relevant work experience in the business field. Most of the major Aus. uni's offer it, an eg would be the MBA offered by UNSW through the AGSM (Australian Graduate School of Management).
Every uni has slightly different costs/structure and prestige. When you talk of MBA's the "prestige" of this degree does count. Some programs are recognised internationally whereas others are not. Many of the top business CEO's in Aus. (have a look at Macquarie Banks profile) hold their MBA's from Harvard etc or other Ivy League colleges. Acceptance into American programs is extremely competitive and expensive and often requires you to undertake standardized grad admissions tests such as the GMAT.
