"Australia has reason to worry about the attacks too. Education is the country's biggest export - after coal and iron ore - and international students contribute $13bn to the Australian economy every year. Australia, by one estimate, could easily lose $70m because of the attacks."

What the FUCK. This is, in the entire article, the only stated reason why Australia should care about these attacks. Yeah, it'd be a real damn shame if you LOST INCOME because PEOPLE ARE BEING KILLED, wouldn't it?
