I don't envy Australian's most things but this is one worthy of it.
But yes, pretty much everything in Australia will try to kill you: it has world's most venomous snakes, world's most venomous spiders, saltwater crocodiles, sneaky dropbears, dengue fever carrying mosquitoes, world's most venomous jellyfish and sea snakes, and, of course, the IT consultants who will eat one alive.
Well. There is nothing left to discuss then.
As to the latter point, no, that's incorrect. There were some issues in the past with getting a game approved at a 15+ age rating instead of 18+, but those have gone by the wayside as videogames in general have become more mainstream & accepted.
