I would like to apply for this school, or perhaps another next year, but I don't know the requirements. Does anyone know the specific requirements or would I need to send a letter to the school and have them tell me?

This school being Sydney Business School.

Not sure if this is what you're asking, but it looks like they want applicants with a bachelors degree, at least two years of "relevant" managerial or professional work experience, and probably some kind of English-language test score.
