It's a very likely alternative, and will certainly be on the agenda these coming years.
I too know a number of Australian's
(go figure) who would like to retain the Australian Monarchy, though they are of a considerable age it must be said.
For every one who does support the monarchy, you'll find three, possibly four or even five, that don't and then those that are undecided and care not of government or politics. Even so, it is EIIR who has the support, not so much the institution for which she inherently stands.
We are an aging population, and those who feel an affiliation with British Imperialism
(long gone in practice, may it be) are dropping one by one and their children
(the baby boomers) are namely of an indapendant mind as are their children and certainly any younger generations that ensue. Young adults and teenagers
(the odd history or political buffs being an acception) have absolutely no regard for the monarchy and probably wouldn't be able to tell you who infact the
Prince of Wales is. You can't blame them really. I mean, a man who makes a fleeting visit once every 5 or so years is hardly going to stir interest, let alone be accorded the right to
'inherit' their Australia. And as this Commonwealth has no royal family, they
(Charles and his family) are of such a minimal importance, whether he is heir apparent or not. He remains an indefinable figure and has been for quite some time. The generational spill over, I believe is well and truly arrived. It is a mere matter of time.
But when's the best time, that's the question for many.
but I suspect that for many of them it's about EIIR specifically
Bingo!
