Except that koalas are not capable of using tools, creating or using weapons and cannot make traps. They have no social structure and lack language. One thing koalas do have, is 4 thumbs - 2 on each hand. So, I guess in this regard, they're more like Aliens than ewoks but the arrangement of the digits is difference. On top of all that, koalas are God awful stupid. As thick as two short planks held together by a leather strap. You won't find them building tree houses or lighting barbecues.
A couple other facts about koalas you may like to be aware of. Koalas are arboreal animals. In which case DO NOT PET OR PICK ONE UP IF YOU FIND ONE OUT OF A TREE! It will shred your skin with ease using those claws and if you do pick one up, you also risk being pissed on. Unless you want to smell like eucalyptus oil fermented in marsupial urine for a week, don't do that. I guess that will scare any Predator off. lol.
Koalas eat only eucalyptus leaves and nothing else. Young koalas cannot eat this vegetation as their intestinal tract isn't capable of digesting the tough leaves until they are older. In order to feed, young koalas lick their mothers asses and feed on eucalyptus flavoured poo. In which case, it's probably not a good idea to be licked by a baby koala no matter how cute they look.
Finally, many koalas have STD. Chlamydia, to be precise.
Enjoy you downunder holiday!
