In Australia, the formal ceremony of granting assent in parliament has not been regularly used since the early 20th century. Now, the bill is sent to the governor-general's residence by the house in which it originated. The governor-general then signs the bill, sending messages to the President of the Senate and the Speaker of the House of Representatives, who notify their respective houses of the governor-general's action. A similar practice is followed in New Zealand, where the governor-general has not personally granted the Royal Assent in parliament since 1875.
