It snows on a couple of the mountains, mainly Ben Lomond and Cradle Mountain, the rest of the state is just really, really cold during winter
I have never been to QLD but apparently our summers feel a lot hotter. 30c here feels like about 40c in QLD because we are so close to the ozone hole. We have some gorgeous beaches and quite often even on a boiling hot day you will be the only person for miles, love taking the dogs for a romp on the sand.
I don't know about the paper mills, there is a new one starting up in the near future. People protested it so it kept getting pushed back further and further but apparently it's all still going ahead.
