Peter Cosgrove was NEVER the Governor-General of the Commonwealth of Australia. He was NEVER the Commander in Chief of the naval and military forces of the Commonwealth. He was NEVER the Queens Representative and he definitely was NEVER appointed by the Queen.
He did nothing for the people of the Commonwealth, in fact he allowed the Australian Government to do harm to the very people he was suppose to protect. He NEVER protected our Imperial Laws, including our Commonwealth of Australia Constitution Act 1900 (UK). But he did manage to sell himself out to a foreign power, the United Nations.
