Latimour, I'm starting to wonder if you really ever did live here. Much of what you say is typically inaccurate. If you don't like Australia why don't you just say so instead of giving people on here misleading information. If you lived here 12 years you should know better.
The weather here has been EXACTLY like that all week and much of the last months. Yes I spend most of my working day in the city and around. The sky is clear blue most of the time. If it's grey, they are a what most people know as clouds. Every time i've been to Sydney, Adelaide and Brisbane it's the same. We have water shortages, lack of rain but Melbourne is never sunny. Go figure.
My point is Aus is a relatively very clean place. Not that Melbourne has perfect weather. But as usually you make all efforts to sidetrack the point and slag off Aus in what ever way possible.
Maybe read up on the difference between weather with pollution.
I've spent a lot of time in every capital city of Australia with exception of Perth and the Darwin and not one single city is anything like what is made out here. Not one. I'm sure given what people say, Pert and NT is also very clear of air pollution in comparison to other cities. I suppose the gold coast and surfers paradise are average also.
The only "special photos" I've seen that depict Melbourne with a smog sky is when there are bush fires.
My comments on LA is not a dig at people there. When I first flew into LA it was a big shock to see so much air pollution. It is what it is. I don't dislike LA, just the air. The price of big population.
