Admiralty House, its grounds and Kirribilli House are usually open to the public once a year,
sometime in spring when the gardens are at their best. However, there had not been a public opening
since the 2001 terrorist attacks in the United States, because of security concerns, until 2005.
There was a public opening once again on the 30th October that year. In addition to the Royal
family, the American President, the Pope and other official "heads of state" have resided at
Admiralty House when in Sydney.
