Australia's population has grown taller over the past century, thanks to improved healthcare, nutrition and hygiene.
A global height analysis of 200 countries measured the average growth of global populations from 1914 to 2014, with every country recording an increase in height. Australian men stand tall as the only non-Europeans in the top 25, coming in at number 18, while Australian women jumped from 29th to 15th place. 
According to the study, published in science journal eLife, Dutch men (182.5 centimetres) and Latvian women (169.8 centimetres) are the tallest on average.
The study found a strong correlation between the height and health of a country's population. While height is partly due to genetics, "children and adolescents who are malnourished, or who suffer from serious diseases, will generally be shorter as adults," the researchers said.
The biggest movers were Iranian men, who grew an average of 16.5 centimetres, and South Korean women, who grew a whopping 20.1 centimetres to 162.3 centimetres.
But some barely grew at all. Women in countries like Madagascar and the Philippines increased by less than one centimetre in 100 years.
