Adjacent to the Opera House, is the Botanic Garden, very interesting. An enormous variety of plants and trees can be seen, the climate allows for almost any species. Tropical species are exhibited in a nice green house. Most plants are good described and much background information is available, so it's a good opportunity to refresh the study biology. We were greeted by two Australian White Ibis Threskiornis molucca. You see them often. It is a large, white wading bird with a naked, black neck and it has a long, downcurved bill.
