New Zealand vs Australia Flag: How to Tell Them Apart
July 21, 2026 ยท 5 min read
The quick answer: Australia's flag has six white stars, including a big seven-pointed star under the Union Jack. New Zealand's flag has four red stars with white borders, and nothing under the Union Jack.
So the fastest way to tell them apart is to look under the Union Jack. A big white star there means Australia. Empty blue means New Zealand. It works even when the flag is tiny on a phone screen.
The differences at a glance
| New Zealand | Australia | |
|---|---|---|
| Stars | 4 | 6 |
| Star colour | Red with a white border | White |
| Under the Union Jack | Nothing | The seven-pointed Commonwealth Star |
| Southern Cross | 4 stars, all with five points | 5 stars: four with seven points, one small one with five |
| Background | Dark blue | Dark blue |
| Shape | 1:2 | 1:2 |
| In use since | 1902 | 1901 |
The blue background, the Union Jack in the corner and the 1:2 shape are the same on both flags, so they will not help you. The stars are where the answer is.
Test yourself: which one is New Zealand?
Six quick rounds. The last three show the flags smaller, the way they look on a phone or on a map.
How often people mix them up
Since September 2026, players in our flag games named the New Zealand flag correctly 86% of the time (155 answers) and the Australian flag 83% of the time (149 answers). That sounds good, but look at the mistakes: when a player got one of them wrong, about a third of the time they picked the other one.
Why the two flags look so alike
Both countries were British colonies, and both put the Union Jack in the top left corner to show that link. Both also chose the Southern Cross, the constellation that sailors used to find south and that you can only see well from the southern hemisphere.
They made those choices within a year of each other. Australia's flag was first flown in 1901, the year the country federated. New Zealand made its flag the national flag in 1902, after using it at sea since 1869. Same idea, same decade, same blue: the two flags were always going to look like relatives.
They look close on the map, too
The flags are not the only trap. On a world map, New Zealand seems to sit right next to Australia, but Sydney to Auckland is 2,156 km of open sea, about as far as London to Kyiv. That distance is one reason New Zealand chose not to join Australia when it federated in 1901, and why the two are separate countries with two very similar flags.
The stars, one by one
New Zealand: four red stars
New Zealand shows the four brightest stars of the Southern Cross. Each one is red with a white border, and each one has five points. The fifth, smaller star of the constellation is left out. There is nothing at all under the Union Jack.
Australia: six white stars
Australia has two groups of stars, all of them white:
- The Commonwealth Star, under the Union Jack. It is the biggest star on the flag and has seven points: six for the six states that formed Australia in 1901, and a seventh, added in 1908, for the territories.
- The Southern Cross, on the right. It has five stars: four with seven points and one small star with five points. That small one is the star New Zealand leaves out.
Count them and you get one plus five: six stars.
Did New Zealand try to change its flag?
Yes. Partly because of the mix-up with Australia, New Zealand held two referendums on a new flag in 2015 and 2016. The first one picked a favourite from five designs: the Silver Fern flag in black, white and blue, by Kyle Lockwood. In the second one, in March 2016, 56.6% of voters chose to keep the current flag. The process cost about NZ$26 million.
Australia has never held a national vote on its flag, although the question of taking the Union Jack off comes up from time to time.
Other flags in the same family
If you play a flag quiz on Oceania, these come up too:
- Tuvalu: a light blue flag with the Union Jack and nine yellow stars.
- Fiji: a light blue flag with the Union Jack and a shield.
- Cook Islands: a dark blue flag with the Union Jack and a circle of 15 white stars.
- Samoa: a red flag with a blue corner holding the Southern Cross, but no Union Jack.
How to remember it for good
- One rule: look under the Union Jack. A star means Australia. Empty means New Zealand.
- A memory hook: Australia is the bigger country, so it gets more stars: six against four.
- Practice beats reading: play a round of the Flags of Oceania quiz or Guess the Flag. There is no timer, so you can take a second to look under the Union Jack until it becomes automatic.
