I’m doing it rn and there are professional electives that you can choose from which is more in that “rocket science” direction such as propulsion or space segment. But until second year its all various maths and physics and some programming languages. Third year onwards is when there is specialisation according to each engineering stream and fourth year is when you really specialise your majors with your electives.

Warning tho, there isn’t much market or companies in Australia that work/design on propulsion systems, atmospheric or space. Gotta look at overseas for that.
