I'd agree that new England is the most similar to England 
But in terms of an actual state, it is harder to pinpoint.
BTW, Australia is most like Oregon, I tink.
Australia is closest to California without a doubt.
Sydney= Los Angeles: warmer in climate, in the spotlight, suburbs are infinately more conservative, younger(in style, not actual age), hipper.
Melbourne=San Francisco: Weather isn't that great compared to LA/Sydney, more left wing all around, tram system, more European and "old world" in flavour, more cultured.
Plus the weather in California is similar to that of NSW, VIC, SA, and WA.
Queensland is obviously closest to Florida: The southern coast is basically like the Miami/South Florida area, then you have the rednecks up north 
. Its also more conservative, as is Florida.
I would say that's spot on.
