Interesting. I wonder whether that Greater London aspect is why there is a 5 times the population density that we have (wikipedia tells me that the London Metropolitan Agglomeration has a population density of 1510 people per square kilometre and that Greater Perth has a mere 310).

..and my last assignment is due tomorrow night, so I'm starting to look at trying to do a proper walk. I did a surprise short walk in some of the Kings Park botanic gardens (wikipedia article here, didn't find a good map of it), but didn't think to take photos - may remember to write it up while I still remember where I went!
