The Malaysian language is the first language of Malaysia's Malay community, but it is also widely spoken by the country's non-Malay citizens. It is often referred to just as Malay. It is closely related to Indonesian - and, while words sometimes differ, communication between the two languages is usually fine. Of Asian languages, Malay and Indonesian are easy to read and write: they use the same Latin script we do in English.  Books and online materials to learn Malay are easily available. If you are thinking of learning Malay in class, think about enrolling in an Indonesian course - available through the Victorian School of Languages, the CAE or at a large number of universities in Australia.
