By the sound of it you are probably from W.A. as this is one of the few states that allows you to ride a scooter up to 50cc on your car licence.
You cannot do that in most other states of Australia and neither can you do it overseas so you either need to get a full bike licence here and then your international driving PERMIT (not licence)will be endorsed to show you can ride a motorbike or you need to get a bike licence in the foreign country you are visiting to legaly ride a bike.
It is a PERMIT and not a licence because it permits you drive/ride the class of vehicle you are licenced to drive in your own country without the need to take an overseas test.
