Though the Constitution refers to possible actions by the Governor-General, it had long been presumed that convention required the Governor-General to act only on the advice of the Prime Minister and the Cabinet. However, as the 1975 constitutional crisis demonstrated, the Governor-General is not compelled to follow the Prime Minister's advice. In these cases, he or she must be personally satisfied that the conditions specified in the Constitution apply, and is entitled to seek additional information or advice before coming to a decision.
