Hello
I have only one question.....You are already holding CPL with IR and still you require a dispatch license? Why?
License for dispatching is only required in countries where dispatch is considered a 'regulated' profession like in Germany you need LBA license (the best), FAA license in USA (good) and GCAA in UAE (average).
You can very well work as dispatcher in Australia if you want to with your present qualification....
Hope this helps......
