Holiday on September 3, 2026 — Australian Flag Day: The History of the National Symbol
On September 3, Australia celebrates National Flag Day. It was on this day in 1901 that the blue Australian flag was officially raised for the first time over the Royal Exhibition Building in Melbourne following a contest in which more than 32,000 people participated.
Australia’s National Flag Day is celebrated annually on September 3. In 2026, it falls on a Thursday. This date commemorates the event of September 3, 1901, when Australian Prime Minister Edmund Barton announced the winners of the international contest to design the flag of the newly formed nation. On that same day, a massive flag measuring 5.5 by 11 meters was raised above the dome of the Royal Exhibition Building in Melbourne. That was where Australia’s first federal parliament was in session at the time.
National Flag Day was officially proclaimed in 1996. Since then, September 3 has become an annual occasion for Australians to reflect on the history of their flag and its significance for the country. In 2026, this date will hold special significance. Australia will celebrate 125 years of the Federation, the adoption of the Constitution, the first session of the federal parliament, and the first official raising of the national flag.
How the Australian Flag Came to Be
Until 1901, Australia was not a single nation-state in the modern sense. There were six separate British colonies on its territory—New South Wales, Victoria, Queensland, South Australia, Tasmania, and Western Australia. On January 1, 1901, they united to form the Commonwealth of Australia. The new nation needed a common symbol that would represent all six colonies. Therefore, the government announced an international competition to design the national flag.
The contest rules called for the creation of two versions of the flag—one for official and naval use and one for merchant ships. The organizers received a huge number of entries. In total, 32,823 entries were submitted from Australia and other countries. The participants included people of all ages and professions. Even an unnamed governor of one of the states submitted a design. Some participants approached the task in very unusual ways: among the sketches were flags featuring kangaroos, including one with a kangaroo leaping through the Southern Cross, as well as a design depicting animals playing cricket.
In the end, the jury selected five nearly identical designs. The cash prize of 200 pounds sterling was split among the five winners. They were Perth artist Annie Dorrington, 14-year-old schoolboy Ivor Evans from Melbourne, teenager Leslie Hawkins from New South Wales, architect Egbert Nattoll from Victoria, and shipping company officer William Stevens. Thus, the modern Australian flag was, in fact, the result of a collaborative effort by people with very different backgrounds.
What Do the Symbols on the Flag Mean?
The Australian flag has a dark blue field. In the upper left corner is the flag of Great Britain—the Union Jack. It serves as a reminder of Australia’s British colonial past. Below the Union Jack is a large white seven-pointed star. It is called the Star of the Federation or the Commonwealth Star. Originally, in 1901, it had six points—one for each of the six colonies that united to form the Federation.
In 1908, a seventh point was added to the star. It was meant to represent the territories of the Australian Commonwealth. That is why the Federation Star has seven points today. On the right side of the flag is the Southern Cross constellation. It is clearly visible in the Southern Hemisphere sky, which is why it has become one of Australia’s natural symbols.
On the flag, the Southern Cross is represented by four seven-pointed stars and one smaller five-pointed star. The constellation was significant even before the modern flag was adopted—it was used on early unofficial Australian flags and other symbols.
Why is Flag Day celebrated on September 3?
The date is not random. On September 3, 1901, Prime Minister Edmund Barton announced the winners of the design competition, and the new flag was officially raised for the first time over the Exhibition Building in Melbourne. This was a significant event for the young Federation. Australia had become a unified federal state only a few months earlier, and its first federal parliament began its work in Melbourne.
The flag became one of the first national symbols of the new nation. It gradually began to appear on government buildings, ships, military installations, in schools, and at sporting events. At the same time, the flag’s path to full recognition as the primary national symbol was not immediate. Initially, it was called the Commonwealth Blue Ensign—the blue flag of the Australian Commonwealth. Later, this very design became Australia’s official national flag.
The red version of the same design was named the Commonwealth Red Ensign. It was used by Australian merchant ships. In other words, the blue and red versions served different purposes, even though they originated from the same design competition.
How the Flag Has Changed Over Time
Interestingly, the modern Australian flag does not exactly replicate the version first raised in 1901. The most noticeable change concerns the Federation Star. On the first flag, it had six points, as it symbolized the six states that formed the Federation. In 1908, a seventh point was added to represent the territories.
The design of the Southern Cross stars also changed. In the original competition design, they had varying numbers of rays—ranging from nine to five. This was intended to reflect the brightness of individual stars.
The design was later simplified. In the official 1903 version, the four large stars each had seven rays, while the smaller star retained its five rays. It is this version that formed the basis of the flag’s modern appearance. In other words, the flag that Australians see today is the result not of a single decision, but of several stages in its development.
How Flag Day Is Celebrated
Flag Day is not like major national holidays with large-scale street festivals. Its main purpose is to display the flag and commemorate the history of its creation. On this day, Australians are encouraged to display the national flag at their homes, schools, businesses, and community organizations. Government agencies are also advised to fly the flag throughout the day. In 2026, the Australian government asked federal departments and their agencies to fly the flag throughout the day on Thursday, September 3. Other organizations were also encouraged to participate.
In schools, Flag Day can serve as an opportunity to discuss Australian history, the Federation, and national symbols with students. Flag-raising ceremonies, themed lessons, and other educational activities are held. For community organizations, this is also an opportunity to share the significance of national symbols and the country’s history. Particular attention is given to how different population groups have shaped modern Australia.
Individual events may take the form of exhibitions, public lectures, or small ceremonies. The scale of the celebration depends on the specific community, school, or institution.
How to Properly Raise the Flag
In Australia, there are official rules for handling the national flag. For example, it is recommended to raise it quickly and lower it solemnly. The flag should not be raised before dawn or left up after dark unless it is illuminated. While the flag is being raised or lowered, those present should face the flag and remain silent. Military personnel and people in uniform salute during such ceremonies.
If the Australian flag is raised alongside other flags, it must occupy the place of honor. It also must not be smaller than the other flags in the same display. It is not recommended to fly two flags simultaneously on a single flagpole. Furthermore, the national flag must not be intentionally flown upside down, even as a distress signal.
There are specific rules for flying the flag at half-mast. It is lowered to half-mast as a sign of mourning. Before doing so, the flag is first raised to the very top and then slowly lowered.
The Australian Flag and Military History
The national flag gradually became an important symbol not only of the nation but also of the Australian military. It was used on ships, in military units, and during international operations. During World War I, the Australian flag was present, in particular, during the Gallipoli Campaign and on the Western Front. In 1915, it was carried by participants in the famous “Cooee” march in New South Wales.
There are also stories that show just how important a symbol the flag became for prisoners of war. During World War II, Australian prisoners of war in Singapore and other camps secretly made flags from available materials. One such flag was made by prisoners of war in Singapore. They used blue fabric they found in their supplies, and red Red Cross scarves for the stars.
Stories like these have become part of the broader history of the Australian flag. It was used not only at official events but also at times when hope, a sense of belonging to one’s country, and a sense of community were especially important to people.
Interesting Facts About the Australian Flag
One of the most interesting facts is that the 1901 contest received 32,823 entries. That was a huge number for that time, especially considering that the designs came from various countries.
There were some very unusual entries among the submissions. For example, one designer depicted a kangaroo with six tails—representing the number of colonies that had united to form the Federation. Another proposed a kangaroo leaping over the Southern Cross.
There was even a sketch featuring Australian animals playing cricket. The judges had to review thousands of very different ideas before selecting five similar winning designs.
Another fact: there were five winners, not just one. Among them was 14-year-old schoolboy Ivor Evans. He became the youngest designer to win the contest.
Another interesting detail concerns Australia’s largest flag. A flag measuring 12.8 by 6.4 meters flies daily over the Parliament building in Canberra. According to the Australian government, its size is roughly comparable to the side of a double-decker bus.
Flag Day in 2026
In 2026, Australia’s National Flag Day falls on Thursday, September 3. This year’s date is also special because the country is celebrating the 125th anniversary of the formation of the Federation and the related events of 1901. Australian government agencies are required to display the national flag throughout the day on this date. Other organizations are also encouraged to join in the celebration.
On the same day, Australia observes Merchant Navy Day, dedicated to Australian merchant mariners and their service, particularly during times of war. Consequently, on September 3, you may see not only the blue national flag but also the red flag of the Australian Merchant Navy. If they are displayed together, the national flag must occupy the place of honor.
For Australians, Flag Day is first and foremost an occasion to reflect on the country’s history and one of its most famous symbols. The flag, which was created as the result of a 1901 contest, has become, over the course of 125 years, an integral part of state ceremonies, military history, school life, and everyday culture in Australia.
