If she has a beef it is with the government. They are the only ones that can change the situation.
Though in reality they are unlikely to do much att all.
Even so, why would shouting at the king be the wrong move?
We understand that even though the title to a piece of government land might list the owner as "H.M. Charles III in right of Australia," this doesn't mean that the government office, military base, or whatever is
literally Charles's personal property. Why can so many people in this thread understand that shouting at H.M. Charles III might not be an appeal for him to fix the problem himself?
Her problem is with the state; why shouldn't she shout at the personal embodiment of the state, regardless of the actual powers of that individual?
I think criticising her actions id especially strange considering they happened in Parliament. I mean, think about the way debates work: all the questions are addressed to the speaker. Should we also ask
"why is that MP asking the speaker about the economic impact of this tax bill? He doesn't know! He should be asking the Minister of Finance!"
In Parliament, whether you're asking the speaker questions or airing your grievances at a king, the people who
can do something about your concern are listening and can respond if they choose.
The better option is for her to be friendly towards the king and get him on her side. Then at least the questions will be looked at seriously.
Why would getting the king on her side help? I thought you said he can't do anything about this situation.
