The multi-billion dollar business attracts crowds of up to 100 thousand, and TV audiences exceed 10 million.

Of the 10 largest sports stadiums in the world? Eight are US college football venues.

But a controversy is brewing involving punters - who kick the ball to the other end of the field - specifically Aussie punters.

Almost half of all punting positions in top-tier American college football are filled by Aussies. Former Aussie Rules players are landing full scholarships to prestigious universities.

While Americans grow up throwing footballs, Aussies grow up kicking them. Australia is becoming a punting breeding ground.

Now, calls are growing to kick the Aussies out.

The father of one American teen punter, launching a class action, accusing the National Collegiate Athletic Association of giving Aussie athletes an unfair advantage - claiming “lenient” age rules are allowing “older, physically mature Australian punters” to snag the spots of younger American hopefuls.

So are Aussies getting preferential treatment, or do they simply possess a divine kicking prowess that leaves their US rivals in the dust?
