How concerned is the Queen over matters in Canada and Australia?

I don't know as I don't know the Queen personally to ask her. From what I know the Queen has said to Australia and its people (not sure about Canada) and said if they wish to become a republic it doesn't matter and she'll support it. I'm 16 so I have no say in the matter yet but I think there's no need to become a republic being under the Queen for the last 200+ years has done us no harm and becoming a republic would be a waste of time and money.
