★★How would u comment on 【pollution】 in Sydney? (scale 1 - 5)?

I've been here for 3 days and I would say that the pollution level is between a 1 and 2. When it isn't raining the sky is extremely blue and you can easily get a sunburn if you don't wear your sunscreen. BTW: I am from California where the pollution can get pretty bad, so I am enjoying my time here!

For a more official answer check out the City of Sydney's Air Pollution web site

I'm in agreeance with the other! 1.5! It's pretty good! :)

Tried finding a list of countries for pollution but couldn't. Sorry!

I would say parts of Sydney are 1 and parts are 2. It's generally very good, but if you stand beside a major road all day you may find it a bit polluted. Also sometimes when the weather is very still for several days in summer a mild haze can develop.
