But, these are not your average Aussie men.

At 1.88 metres and 1.82 metres tall respectively, they stand a good head above the average Aussie - who we might name Jack, given that is the most common boy's name in the country. 

Jack doesn't cut quite the honed physique of Jackman or have the height of Crowe. Rather, he stands at 175.6 centimetres tall and weighs in at 85.9 kilograms.

This gives Jack a Body Mass Index (BMI) of 27 putting him squarely in the middle of the overweight category and a few kgs shy of the medically defined obesity range.

Jack is shorter, but slightly leaner than Todd though - the average American man, whose BMI is 29, one below obese and who is 176.4. 

Jack and Todd are both more rotund than their counterparts in Japan, the Netherlands and France. Mr Average Japan is the shortest of the group at 171.4 centimetres and has the lowest BMI at 23.7. He also lives the longest and is the healthiest of the group.

Mr Average Netherlands is the tallest at 183.3 centimetres and has a BMI of 25.2, just tipping him into the overweight range, while Mr Average France, with a diet rich in cheese and wine, is 174.4 centimetres and has a BMI of 25.5. 

In a fascinating visual comparison of Mr Average World, one graphic artist has taken the public health data of men around the world to come up with models of Mr Average and stand them side by side. 

There are the obvious health implications of being overweight, which increases your risk of developing coronary heart disease, as well as other health conditions such as diabetes and impacts on blood pressure and cholesterol levels.

Aside from this, it is interesting to note that while Todd or Jack or any of the other Mr Averages may not be specimens of perfect health or conditioning, this does not necessarily make them unattractive to women.

A new study has found that uber masculine-looking men with buff Hollywood bodies are not the epitome of attractive in some countries. 

In some cultures, softer, less masculine-looking men are more appealing to women, said the study published in Proceedings of the National Academy of Sciences.

"In South America," for example, "women preferred feminine-looking men," said lead author, Isabel Scott, a psychologist at Brunel University, in Uxbridge. 

"It was quite unexpected."  

So although the "perfect" man looks different to men and women and different again according to the country you're in, it seems Mr Average might not be so average after all. It just depends on who you ask.
