We enjoyed much seeing koalas so close, though we had seen even closer in our trip. The good thing is there are many: babies, youngsters, adults and older koalas and staff makes sure they would be close enough to paths by putting fresh eucalypti leaves nearby. Also, they were careful and making sure noone touched the animals, which I appreciate (apparently, people can't help caressing them when they see them so close).
We were also able to see a wallaby in the bigger loop, so I recommend you try that too.
