Why has this country become Tinder's favourite testing ground?

It has a relatively small population, it's English-speaking and it has an estimated smartphone penetration of 84 percent -- all qualities that make it the ideal place for Tinder to test its new features, according to the dating app's founder.

And that's why features like Tinder Social, which allows users to set up group dates, were piloted here first. "Australians are, I guess, really early adopters -- more open minded and quicker to try new things," he said, "and that's why we test all of our stuff here first." Tinder's sixth largest market, Australia is also culturally similar to its primary locations like the United States.
