Thopa, Which part of Australia is your friend planning to move to? The education system might differ from state to state. Generally speaking Australia is a very beautiful place to live. I personally believe that it is one of the most peaceful country in the world. I presume that by class you mean university classes right? Anyway in terms of semesters, we have two semesters each year, each going for roughly for a period of 4 months and your classes depend on your chosen sub/ course. When do you want to have the classes depends on your course and on also on your personal life. Universities here are pretty flexible in terms of timetables. The first semester for the year begins in Feb/ March and ends in May/ June and the 2nd sem begins in July and ends in November. In terms of language. Aussies neither use British English nor American. Aussies have their own distinct English. Although, the written system might be similar to that of Britain, Aussies have their own slang and the Aussie accent also differ from British and American . Aussies generally tend to speak a lot slower than Americans. Anyway I wish your fren all the best. While your fren is moving from US to Aus, I'm planning to move from Aus to US. And my reason of moving to US is not beacuse I don't like Australia, but I want to be with my family in the USA.
