When Amy Lamont speaks at Sydneys climate rally on Wednesday, her bags will already be packed back at her family home in case a bushfire forces her to evacuate.

Lamont lives right by the Garigal National Park in Sydneys north, and was on the verge of fleeing her house last week when savage flames crept up as close as two kilometres from her front door.
