I'd move closer to the epicentre. Ain't no way I'm dying from sloughing skin and radiation in a now post-apocalyptic Melbs; let me go out instantly lol
So this sent me to look up what is the instant death radius of a nuclear bomb. It depends on the size of the bomb of course, but within 3km, very likely to be dead, up to 8km, 50% chance of dead. Survival is possible if you are in some kind of bunker or heavily sheltered concrete building. But I don’t know if those numbers include death from chunk of concrete falling on head or just radiation. Beyond 8km will be some death dependant on exposure. So being past the 8kms and in a basic brick veneer house, I would likely die a slow death with my skin peeling off. Would probably eat and drink the nicest things I could find try for the first few days before symptoms set in properly, drive to a lovely location in nature, and then find a way to exit before it became unbearable.
I'm probably far enough away my concerns would be the social breakdown and chaos of the afermath rather than radiation. I guess I'd try to contact my family if communications are still up, then set the pets up with lots of dry food as a precaution and go to work (in emergency services).
Judging by Calhoons response to this question I'm outside any blast radius. Damn, and I was hoping the family would be blissfully vaporised together. Now we'll have to hit the road in a futile attempt to find a way to eke out a living among the fleeing hordes. We'll probably get as far as Crazyburn and then run out of petrol lol.
