I don't call myself a monarchist. But I am in favour of someone holding the power to send us to an election if we get a non-functional government. Whoever that is needs to be totally independent of our day-to-day politics and essentially un-bribable.
Right now, that's the king in England. I'm not against disconnecting from that - but like I said, I don't know where else you'll find someone who is outside daily politics in Australia and can't be bribed to act against our interests. If you have a name, I'm all ears (so is the king! 😆).
If you are proposing we just do away with that, then I'd love to know how you'd deal with an Australian Trump administration. Because 3-4 years of that doesn't sound fun.
