@kcarruthers It will be bloody scary, there is fire damage as you head through Lady Game Drive ( I have no idea if I have that correct ) where you can see the trees recovering.
@kcarruthers Canberra was on fire in 2003, so we already know the answer.
@kcarruthers that is why they say to leave early. Leaving late is a recipe for disaster.
