Australian frogs are coming to the boil.
Irony at its finest.
Most of Australia's laws, our parliamentary system etc was based on UK Westminster system. In the early years of our country most people were very pro British Empire. There was enormous social pressure on people to go and "fight for the empire" during World War 1 lots and lots of Australian went and fought and died in Europe, then the same thing happened in World War 2, except suddenly the Japanese were threatening us (A lot of people don't know the Japanese bombed Australia cities during WW2) and most of our military was over in Europe and Northern Africa after the fall of Singapore Australia realized how vulnerable we were and that British could not be counted on to defend us, which caused a strategic realignment behind US and things like the ANZUS treaty etc.
To this day there is still a lot of positive British sentiment in Australia. A lot of people here really like the Queen it's a little bizarre, not so evident in the city but if you go into regional country towns it is pretty pro monarchy. When I was in high school the Queen visited my area and it was crazy big parades huge event I have never seen another politician of any sort anywhere in the country get the kind of reception she did. Most people here are completely cynical about politicians but they love the queen - weird.
The "royal weddings" (good lord, kill me now) do their little bit in fluffing up pro-monarchy anachronistic romantic notions in some of the younger set, but nowhere near the amount needed to sustain the 'no to a republic' vote even in the next ten years.
My assumption is that a lot of these same monarchists are fundamentally racist as a direct result of the various wars, which is semi-understandable. Humans don't tend to change their minds beyond a certain age, no matter the changing context.
There's a quote somewhere about "beliefs don't change, their proponents die out". I'm finding it applies in almost universal contexts.
Also the general opinion appears to be that we'd rather be a Republic than have Charles as our king ;)
I can't stress enough the potential for harm in any attempt to bypass various laws.
The Australian Government even refused to allow independent Medical Doctors into their off-shore immigration detention centres for fear of the detention conditions being made public.
Australia did nothing to even consider trying to maybe help Julian Assange, an Australian citizen seeking protection from nation-backed harassment, way back when, and two Australian citizens were murdered by the Indonesian Government for drug trafficking (Australia negotiated prior to the event, but no negative action was taken afterwards). These are admittedly both divisive examples - with the intention to point out that it depends on the direction of political winds as to how the Australian Government will react.
Australia is a good place to live and the anecdotes above are specifically chosen as the far end of the bad scale, but if you choose a fight with any of the few specific issues the Government is paranoid about or sensitive to, you may face significant resources aimed at your incarceration.
Just make sure your ass is thrice covered if you're going to go up against it...
