Roxy,
of course we would all wear a respirator, but it leaves such terriblle tan-lines.....by the way there are also a few 'airlines' in Australia.
But seriously if you intend to be here, and have children already, or plan to have children. This is a sincere recommendation - do not come. If you plan to come here as a single person and never have children, go for it, it's your life.
Best Regards,
