Misleading title. Nobody is arguing for Australia to cut political, diplomatic, military, trade, etc. ties to the UK - they just don’t want to have a monarch. Seems reasonable to me.
It’s definitely cutting ties. Red China’s slowly taking over.
Very reasonable and very desired by a great number of Australians. Was discussing it with an Aussie friend just a couple of weeks ago. He said he hoped he lived long enough to see Australia free from England.
If some prince in the past had actually been the bastard son of the queen's paramour, then the current line is invalid.
The correct line of succession leads to a middleclass family man living in ... you guessed it ... Australia.
