Australia is an independent country within the commonwealth
realm which does not need to support the Queen financially like the
british do.
Incidentally the Commonwealth realm also includes Canada, New
Zealand, Jamaica and other countries , all independent but choose
to save money by recognising the Queen .
So are you calling Canada, New Zealand , Jamaica etc second class
of UK?
I say it's cleverer to let the british do the primary support of
the Queen than the rest of the Commonwealth Realms. Free ...don't
want ah?
