Learn about the flag


When you're visiting Parliament House, don't miss out on seeing Canberra's most recognisable landmark up close: the stainless steel flag mast with the Australian flag flying above Capital Hill.

The flag mast is the main focal point of the Parliamentary Triangle and you can walk directly under it when you explore Parliament House's grass roof. You can also see it from vantage points all around Canberra.

The design of the flag mast pays homage to Walter Burley Griffin's plan for a pyramidal Capitol building—a ceremonial public space that would celebrate the achievements of the Australian people—which he envisioned as the centrepiece to his design for Canberra.

Its apex, above the exact centre of Parliament House, marks the intersection between the building's 'law-making axis', on which the House of Representatives and Senate chambers are located, and its 'land axis', which runs from the forecourt and contains key public areas of the building as well as many of the major architectural commissions.

This intersection symbolises how the elements of Australian democracy—the people, the parliament and the government—are all brought together under one flag.

Changing the flag

There are between ten and fourteen flags that are rotated regularly so they wear evenly. It takes a team of three specially trained people from the Department of Parliamentary Services to raise and lower the flag. It is usually changed on the first Wednesday of the month.
