‘I didn’t feel safe inside’: navigating public health advice, housing and living with bushfire smoke
Bushfires, and resulting bushfire smoke, were major environmental, social and health crises in Australia in the summer of 2019–20. In Australia’s national capital the smoke pollution index topped global charts, and public health communications were rapidly developed that advised…
