After reading the incidents you've shared from Australia, I would say one thing. "This is normal everywhere, we can not control all people, but we can reduce the number of people who do this.

This isn't normal immature behaviour.

Rape cases are increasing incredibly in Asia too, many families do not speak against just to protect their respect, but they forget that the real respect has already gone. We still can't control the rapist but we can implement some hard punishments for them, when one will be punished & others will see, they may think several times before doing that sin.
So, control is in our hands, but we can never end these kinda criminals.
