How can you tell the flags of Australia and New Zealand apart?
The flags of Australia and New Zealand are among the best-known examples of national flags that are easy to confuse. Both have a dark blue field, the Union Jack in the upper-left corner and the Southern Cross on the right-hand side of the flag.
The short answer is this: Australia's flag has a large white Commonwealth Star below the Union Jack as well as five white stars forming the Southern Cross. New Zealand's flag has no Commonwealth Star, and its four Southern Cross stars are red with white borders. The easiest rule to remember is: Australia = more white stars, New Zealand = red stars.

Why do the flags look so similar?
The flags of Australia and New Zealand look similar because both are based on the British Blue Ensign tradition. Both countries were part of the British Empire, which is why the Union Jack appears in the upper-left corner of their flags.
Another feature they share is the Southern Cross. This constellation is visible in the southern sky from both Australia and New Zealand, making it a natural regional symbol for the two countries.
The similarity is therefore not a coincidence. The flags share a historical background, the same British flag tradition and a symbol linked to their location in the Southern Hemisphere.
What does the Australian flag look like?
Australia's flag has a dark blue field. The Union Jack appears in the upper-left corner. Below it is a large white seven-pointed star known as the Commonwealth Star, or Federation Star.
On the right-hand side of the flag is the Southern Cross. It is represented by five white stars. Four of them have seven points, while the smaller fifth star has five points.
Australia is easiest to recognise by two details: the large white star below the Union Jack and the white stars on the right-hand side of the flag.
What does the New Zealand flag look like?
New Zealand's flag also has a dark blue field and the Union Jack in the upper-left corner. On the right-hand side is the Southern Cross, but its stars are red with white borders.
There is no large Commonwealth Star below the Union Jack on New Zealand's flag. This is one of the easiest ways to distinguish it from Australia's flag when the colour or number of the smaller stars is not immediately clear.
An easy way to remember New Zealand is: red stars, no large star below the Union Jack.
Why is the Union Jack on both flags?
The Union Jack appears on both flags because Australia and New Zealand were part of the British Empire. It reflects the countries' historical ties to Britain and the British flag tradition.
The presence of the Union Jack does not mean that Australia or New Zealand is part of the United Kingdom. Both are independent countries. On their national flags, the Union Jack remains as a historical symbol.
What is the Commonwealth Star on the Australian flag?
The Commonwealth Star is the large white star below the Union Jack on the Australian flag. It is also known as the Federation Star. Six of its seven points represent Australia's six states, while the seventh represents the country's territories.
This star makes the Australian flag particularly easy to distinguish from New Zealand's. If a dark blue flag has the Union Jack and a large white star directly below it, it is Australia.
In a flag quiz, this is a useful detail to notice. Many people first look at the Southern Cross on the right-hand side, but the quickest clue is often on the left: Australia has the large Commonwealth Star below the Union Jack, while New Zealand does not.
What does the Southern Cross mean?
The Southern Cross, also known by its astronomical name Crux, is a constellation visible in the southern sky. It has long been associated with navigation and has become an important regional symbol in several countries of the Southern Hemisphere.
On the flags of Australia and New Zealand, the Southern Cross reflects the countries' geographical position in the Southern Hemisphere. It is also a strong visual identifier: both flags follow the British Blue Ensign tradition, but the Southern Cross gives them a distinctly South Pacific character.
The difference lies in how the constellation is shown. Australia's flag has five white stars representing the Southern Cross. New Zealand's has four red stars with white borders.
How can you quickly tell the Australian and New Zealand flags apart?
The quickest way to tell the flags of Australia and New Zealand apart is to look at the colour and number of the stars. If the stars are white and there is also a large star below the Union Jack, the flag is Australian. If the Southern Cross stars are red with white borders and the large star is missing, the flag is New Zealand's.
- Australia: Union Jack, one large Commonwealth Star and five white stars in the Southern Cross.
- New Zealand: Union Jack and four red, white-bordered stars in the Southern Cross.
- Australia: more stars overall.
- New Zealand: the red stars are the clearest visual clue.
A simple memory trick is: Australia = large white star, New Zealand = red stars.
Has New Zealand considered changing its flag?
Yes. New Zealand has debated changing its flag for many years, partly because the current design is similar to Australia's and partly because the Union Jack emphasises the country's British colonial history.
In 2015 and 2016, New Zealand held two referendums on a possible flag change. Several alternative designs featured the silver fern, one of New Zealand's best-known national symbols. In the final referendum, voters chose to keep the existing flag.
The result shows how recognition and historical continuity can remain important even when a national flag is easily confused with another country's. New Zealand continues to use the flag that closely resembles Australia's.
What other flags can be confused with Australia's flag?
Australia's flag is most often confused with New Zealand's, but several other national flags also reflect the British Blue Ensign tradition. Fiji and Tuvalu, for example, both place the Union Jack in the canton on a blue field, although their colours and other symbols are clearly different. The Cook Islands also use a Blue Ensign-derived design, with a ring of white stars on the fly.
For Australia, the star pattern remains the most useful clue. If the flag has the Union Jack, a large white star below it and the Southern Cross on the right, it is Australia. If the large star is absent and the Southern Cross stars are red, it is New Zealand.

How can you tell the flags apart in a flag quiz?
In a flag quiz, it helps to identify the Australian and New Zealand flags step by step. First notice the Union Jack. Then look beyond it and check the colour, number and position of the stars.
- If there is a large white star below the Union Jack, the answer is Australia.
- If there are five white stars forming the Southern Cross on the right-hand side, the answer is Australia.
- If there are four red stars with white borders on the right-hand side, the answer is New Zealand.
- If there is no large star below the Union Jack, it is not the Australian national flag.
Once you compare the colour, number and position of the stars, the difference becomes easy to recognise even in a fast-paced flag quiz.
In short
The flags of Australia and New Zealand look similar because both are based on the British Blue Ensign tradition and both feature the Southern Cross. Australia's flag has a large white Commonwealth Star below the Union Jack and five white Southern Cross stars on the right. New Zealand has no large star below the Union Jack, and its four Southern Cross stars are red with white borders.
