The Australian Army's officer training academy was established in 1911 and pre-dates the city of Canberra by two years. Its grounds are open to the public, though access to most buildings is restricted. The Changi Chapel, halfway along Miles Road, was constructed by Australian prisoners of war being held in Singapore during World War II and was moved to Duntroon following the war.

An 18-hole par 70 course set within the defence grounds of Duntroon. The public is permitted to play via booking, and the course hosts regular club and social competitions. Facilities include a small clubhouse, equipment hire, and an outdoor barbecue area.
Mount Pleasant Lookout
The hill which overlooks the Royal Military College — Duntroon and the nearby Australian Defence Force Academy is topped by the modest Royal Australian Artillery Memorial, which includes two historic cannons. The grave of General William Bridges, the first commander of the Australian troops at Gallipoli, is just off General Bridges Drive at the base of Mount Pleasant: Bridges was killed in May 1915 and is one of only two Australians killed in the war to have been returned home for burial (the other being the Unknown Soldier at the nearby Australian War Memorial).
Historic Duntroon Dairy
Built in 1832, this building is believed to be the oldest building in the ACT standing. It's only open on request, but you can still see the building very close to a small carpark off Kelliher Dr. There's plenty of informative signage, and you'll see some excellent views over Lake Burley Griffin.
ADFA
While the grounds of ADFA are open to the public they are of little interest to travellers. There's an excellent collection of books on military history in the ADFA library, and the library also sometimes has small exhibitions of historic items on its upper level. If you happen to be around in the area on the last Saturday in August, the Academy's open day is worth checking out – it boasts interesting displays of current military hardware, including armoured vehicles and helicopters, and displays of military marching and infantry tactics by the cadets.
This large office complex houses the administrative headquarters of the Australian Defence Force and the Department of Defence. While none of its buildings are open to the public, visitors can walk around the area. The large Australian-American Memorial is the only sight of any interest, however.
This carillon on Queen Elizabeth II Island was given as a gift by the British for Canberra's 50th anniversary and symbolises the relations between the United Kingdom and Australia. It's got 57 bronze bells, each weighing somewhere between 7 kg, and 6 tonnes (metric tonnes that is), and the tower rises to 50 metres.
