Melbourne Zoo has a good environment, with woods and lawns, winding paths and a wide range of animals, but not many of them. By the way, it's expensive. I suggest you bring something to eat. The zoo opens at 9:00, but it doesn't have to go too early. Many animals are late for work. For example, the lion was released at eleven or twelve o'clock to eat rabbits... Nevertheless, the lion is very conscious of his work and takes him to the glass to show tourists the Australian characteristics of eating rabbits (hiahiahia kangaroos), duckbills and so on. Don't miss it!
