Hello, I'm looking to learn about Melbourne, Australia. 
 There are many national parks that have been designated around the urban area of Melbourne, including the Mornington Peninsula National Park, Port Phillip Heads Marine Park in the southeast, Organ Pipes National Park to the north and Dandenong Ranges National Park to the east. 
 I don't have the answer to that but, I can tell you that the Hoddle Grid is a grid of streets that forms the nucleus of Melbourne's central business district. 
 Oh wow! Do they have like an industrial district? 
 So that means more than 2/3 people in the city belong to some religion. Interesting. Next thing, what can you tell me about the urban structure in Melbourne?
