Flag of Australia
Flag of Australia

In 2024, the country of Australia welcomed 292,318 babies: 142,019 girls and 150,299 boys.

What were the most popular names among Australia’s newborns that year?

We don’t know for sure, because Australia doesn’t release baby name rankings that cover the entire country. But we can look at eight sets of regional Australian rankings — representing Australia’s six states and two most populous territories — and then make a guess about the country’s top names overall.

Here are the rankings, ordered by total number of births per region (highest to lowest):

In 2024, New South Wales welcomed 86,978 (29.8%) of Australia’s babies.

Using the data above, let’s make a guess about Australia’s top baby names overall.

Here’s what I came up with:

Possible top girl names (Australia, 2024)Possible top boy names (Australia, 2024)
1. Charlotte
2. Amelia
3. Isla		1. Oliver
2. Noah
3. Theodore

What are your thoughts on these? (Which names would you have put at the top?)

P.S. I guessed that Isla and Oliver were the #1 names in the country in 2023…
