I think that grossly misunderstands what happened in Australia with the Whitlam government dismissal.

The executive power in Australia is held by the Governor General who "represents" the Queen, but is limited by the constitution in what powers can be exercised. The Monarch of Australia essentially has no power in Australia. The Governor General can largely only do what he/she is told by parliament or resign. The "crisis" part here was that the Governor General found a grey area, the current Prime Minister could not form a majority in the lower house and so the Governor General appointed the opposition leader as the Prime Minister who immediately asked the Governor General to dissolve parliament. It was dubious that the Governor General could actually do this, and it has since been codified in law that he/she cannot.

The Governor General did discuss the matter with the Queen, but largely she had no part in this decision. In fact the released correspondence between the Queen and Governor General shows the Queen declined to make a decision.
