In Australia, the King and the Governor-General enjoy forms of legal immunity primarily stemming from the principle of sovereign immunity. Sovereign immunity is a legal doctrine that protects heads of state from being sued or prosecuted for actions carried out in their official capacity.

For the King, as the head of state, he cannot be legally prosecuted or sued while performing his royal duties. This immunity is rooted in the constitutional framework of Australia, where the monarchy’s role is largely ceremonial, and the King acts on the advice of the government.

Similarly, the Governor-General, who represents the King in Australia, has immunity from legal action for acts done in their official capacity, which includes executing laws and performing ceremonial functions. However, this immunity does not extend to actions taken outside of their official duties or personal conduct. In practice, the Governor-General acts on the advice of the Prime Minister and the government, which further emphasizes their role as a constitutional figure rather than an individual exercising personal power.

Overall, the immunity of the King and Governor-General is significant in maintaining the integrity of the constitutional framework and allowing for the uninterrupted functioning of government, but it does not provide blanket protection against all forms of accountability outside their official roles.
