Queen Victoria signs the Royal Commission of Assent on 9 July 1900, the Bill providing for the creation of the Commonwealth of Australia. [1]

The Commonwealth of Australia Constitution Act 1900 represents the 'blueprint of the Commonwealth'. It describes how the new federation will be established and provides the authority for the powers of the legislature, the executive and the courts. Section 125 of the Constitution describes how the seat of Government of the Commonwealth will be established:

The seat of Government of the Commonwealth shall be determined by the Parliament, and shall be within territory which shall have been granted to or acquired by the Commonwealth, and shall be vested in and belong to the Commonwealth, and shall be in the State of New South Wales, and be distant not less than one hundred miles from Sydney. Such territory shall contain an area of not less than one hundred square miles, and such portion thereof as shall consist of Crown lands shall be granted to the Commonwealth without any payment therefor. The Parliament shall sit at Melbourne until it meet at the seat of Government. [2]

On 17 September 1900, Queen Victoria proclaims that the Commonwealth of Australia will come into existence on 1 January 1901. [3]

Australia becomes a nation on 1 January 1901 when the six colonies federate, and the Commonwealth of Australia is proclaimed in Centennial Park, Sydney.

Lord Hopetoun is appointed as Australia's first Governor-General. Edmund Barton (Protectionist, Member for Hunter, NSW, 1901‒03) is sworn in as Australia's first Prime Minister.

On 9 May 1901, the first Parliament of the Commonwealth of Australia is opened by His Royal Highness The Duke of York and Cornwall (later George V), on behalf of King Edward VII.

The members of the Australian Parliament assemble for the first time in Melbourne on 9 May 1901. As a result of polls held in all states on 29 or 30 March 1901, the Parliament comprises 111 members (36 senators and 75 members of the House of Representatives). The Constitution provided the wording for oath and affirmation, made by every senator or member since 1901, before taking his or her seat:

I, A.B., do swear that I will be faithful and bear true allegiance to His Majesty King Edward the Seventh, His heirs and successors according to law. SO HELP ME GOD!

I, A.B., do solemnly and sincerely affirm and declare that I will be faithful and bear true allegiance to His Majesty King Edward the Seventh, His heirs and successors according to law. [4]

The opening of the first Commonwealth Parliament takes place at the Exhibition Building, Melbourne, and is captured in a painting by Tom Roberts on display in Parliament House. The new Constitution specifies that 'The Parliament shall sit at Melbourne until it meet at the seat of Government'. [5] The location is not specified, although the predominant view is that the new Commonwealth Parliament should occupy the State Parliament building in Spring Street. The matter is the subject of debate amongst the State parliamentarians, some of whom express reservations about having to move from their building. In 1900, however, the Victorian Parliament passes the Commonwealth Arrangements Act 1900 containing provision for the Commonwealth to occupy either the State Parliament building or the Exhibition Building. The Victorian Premier, Alexander Peacock, writes to the Prime Minister, the Rt Hon. Edmund Barton (later Sir) (PROT, Member for Hunter, NSW, 1901‒03), asking which building the Commonwealth Parliament will select to use. The Prime Minister inspects both sites with members of his ministry, and advises that the Commonwealth has chosen the State Parliament House. The Commonwealth Parliament meets in the State Parliament building for 26 years following Federation, much longer than anticipated in 1901, and moves to Canberra when the provisional Parliament House is opened in 1927. During this period, the Victorian State Parliament occupies the Exhibition Building. [6]

The Congress of Engineers, Architects, Surveyors and Others Interested in the Building of the Federal Capital of Australia meet in Melbourne from 6‒17 May 1901, coinciding with the opening of the first Commonwealth Parliament, resolving that 'the Federal Capital should be laid out in the most perfect manner possible'. [7]

The process of finding a location for the nation's Parliament House begins, in accordance with the directions for the national capital laid out in Section 125 of the Australian Constitution:

The seat of Government of the Commonwealth shall be determined by the Parliament, and shall be within territory which shall have been granted to or acquired by the Commonwealth, and shall be vested in and belong to the Commonwealth, and shall be in the State of New South Wales, and be distant not less than one hundred miles from Sydney. Such territory shall contain an area of not less than one hundred square miles, and such portion thereof as shall consist of Crown lands shall be granted to the Commonwealth without any payment therefor. The Parliament shall sit at Melbourne until it meet at the seat of Government. [8]

It proves to be a complex process requiring protracted investigation and debate, taking until 1909 for Parliament to decide that the new capital would be in the southern part of New South Wales, on the site which is now Canberra. [9]

In February 1902 senators and members of the Commonwealth Parliament make the first of several tours of potential sites for the national capital. [10]

The Capital Sites Enquiry Board, appointed in 1902 by the Hon. Sir William Lyne (PROT, IND, Member for Hume, NSW, 1901‒13), the first Minister for Home Affairs, examines nine potential sites for the capital city of the new nation. The Royal Commission on Sites for the Seat of Government of the Commonwealth is subsequently established, and the Commission report is tabled in the Commonwealth Parliament on 17 July 1903. The Commissioners favour Albury or Tumut.

The Hon. Sir William Lyne (PROT, IND, Member for Hume, NSW, 1901‒13) introduces a Seat of Government Bill which results in a House of Representatives ballot in October 1903 to decide on a site for the nation's capital. Tumut is selected but the Senate amends the Bill replacing Tumut with Bombala, and the matter remains unresolved while the nation votes at the second Commonwealth election in 1903. [11]

Surveyor Charles Scrivener reports on site options for the national capital and recommends Dalgety. [12]

The second Commonwealth Parliament passes a Seat of Government Act on 15 August 1904, confirming Dalgety as the site of the future national capital.

The NSW Government disagrees and refuses to cede the land to the Commonwealth. The Watson Government loses office two days later, and successive governments continue to debate where the new capital should be located. [13]

After seven years of debate on the most suitable site for the new capital, the Commonwealth Parliament passes the Seat of Government Act 1908 on 14 December 1908, designating the Yass‒Queanbeyan area for Australia's Capital Territory. [14]

The Act repeals the Seat of Government Act 1904, which had determined an area near Dalgety. This choice was unacceptable to the Government of New South Wales, and the matter was reconsidered. The NSW Government cedes land in the Yass‒Canberra district by the Seat of Government Surrender Act 1909. [15]

The Commonwealth Parliament passes the Seat of Government Acceptance Act 1909 and the New South Wales Parliament passes the Seat of Government Surrender Act 1909 enabling the Commonwealth to formally acquire the territory for the new capital from New South Wales. [16]

The Territory is known as the Federal Capital Territory until 1938, when it is renamed the Australian Capital Territory by amendment to the Seat of Government Act 1908.

Following the Commonwealth's acceptance of a capital in the Yass‒Canberra district, Prime Minister the Hon. Andrew Fisher chooses Charles Scrivener to determine the best site for the new capital.

In March 1909 Scrivener establishes a camp on the slopes of Kurrajong (later Capital) Hill to undertake his survey work. [17] Between 1908 and 1914 Scrivener produces a large number of maps and at least three major contour maps of the Canberra city site. His second contour map, produced in 1910, is circulated to entrants in the national capital city design competition, which is ultimately won by Walter Burley Griffin. [18]

Charles Scrivener establishes survey camps in 1909 and 1910 on the hill at the foot of Kurrajong Hill known as Camp Hill. The first camp is dismantled after three weeks, and another camp set up in the same area in 1910.

A concrete building survives from this period and is entered in the ACT Heritage Register. The building, known as 'Surveyors' Hut', is all that remains of the original Federal Capital Survey camp. It is also one of the earliest extant Commonwealth buildings in the Australian Capital Territory. [19] Many such camps are subsequently established to accommodate workers.

On 1 January 1911 the Commonwealth Government assumes control of the Northern Territory and the Federal Capital Territory , after the New South Wales Parliament passes legislation to cede 2360 square kilometres of land, including the seaport of Jervis Bay. [20]
