Dude no. Koalas aren't cute and cuddly. Okay the babies are...but the adults are stinky hump monsters that snort and tear holes in you with their teeth if you try to touch them. Nopenopenope.
I know that and you know that - but every city / suburb person I know who is going to Australia for some reason wants to "go into the outback" and pet the koalas and kangaroos. It's all I can do to resist suggesting that they break into the zoo and have a practice session with the buffalo (I think in Australia and Europe you call them bison.) Or at least have a close visit with a jack ***, Shetland stallion, or Jersey bull first. They have no idea that a kangaroo can rear back on its hind legs and gut you. I think they never hung out with any zookeepers or lived any place where the wildlife considered one either a threat to be stomped or not quite fast enough food.
In California someone planted eucalyptus over the state, which makes life interesting in fire season. The trees themselves are very odorous and contain all sorts of intoxicants. Something I have always wondered is if koalas have extremely sophisticated livers and if they spend their lives stoned out of their minds.
